JORC Resource for Nicanda Hill anticipated by early 2015
Triton Minerals Limited (ASX: TON, “Triton”, “the Company”) is very pleased to confirm that in this early stage of the RC drilling program, Triton has already intersected very substantial graphitic mineralization over a considerable distance on Nicanda Hill prospect in the Balama North Project.
Triton Managing Director Brad Boyle said “The highly anticipated and prospective Nicanda Hill prospect continues to improve on the encouraging results already obtained late in 2013. This is an impressive beginning to the current drilling program, with significant visual identification of graphite mineralisation in all drill holes completed to date.
The intersection of 220 metres of graphite mineralization in a single drill hole with the true extent of the mineralisation yet to be fully tested is a very exciting outcome for the Company.
The potential of the Nicanda Hill prospect continues to rapidly expand with the completion of each drill hole. Triton believes these results are just a precursor to the true untapped potential of this very large world class graphite project and is yet to be fully demonstrated and realised.”

The initial phase of the reverse circulation drilling program is well underway on the Nicanda Hill prospect in License 5966 of the Balama North Project. The program is designed to test the width and potential continuity of the interpreted graphitic zone as defined by geophysics. The Nicanda Hill anomaly is further and better illustrated in Figure 1 below.

The tonnages for the Exploration Targets for the Balama North Project, first announced on 5 February 2014, give a combined Exploration Target of between 730Mt to 1,200Mt at an assumed average graphite carbon grade between 5% and 6% allowing for dilution of low grade or non-graphite bearing material The potential quantity and grade of the Exploration Targets are conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further drilling and sampling will result in the estimation of a Mineral Resource. Datum: WGS84 Zone 37S.
To date Triton has completed six (6) RC drill holes of the current program on the Nicanda Hill prospect (Figure 2). Refer to Tables 1 and 2 below for a summary of the location, orientation details and geology for RC drill holes GBNC001 to GBNC006.
RC drill holes GBNC004 to GBNC006 were drilled to West on the same drill section as the original two (2) diamond holes TMBD0005 and TMBD0006, which were completed by the Company on the prospect in November 2013.

ASX Media/Announcement 19 May 2014
The current drilling program is focused in the area around these two (2) diamond holes at the Nicanda Hill prospect, because, as previously announced by the Company on 10 December 2013, drill hole TMBD0006 intersected multiple zones containing graphite for a cumulative drilled width of 156m and the hole was terminated in graphitebearing rocks due to the deteriorating weather conditions and, as such, the graphite mineralisation remained open at depth.
Observations from the current RC drilling support the original diamond hole results, confirming the presence of the substantial graphitic mineralisation across the a very wide anomalous zone on Nicanda Hill.
Further, this area is a high priority for the Company as announced on 22 January 2014. The diamond drilling results confirmed numerous occurrences of high grade graphitic mineralisation at and just below surface and continuing to depth, with very high grades of up 28.6% graphite carbon intersected only 17m down hole in TMBD0005.
Additionally, the Company is very encouraged by the fact the graphite mineralisation in the RC holes are showing numerous physical similarities to the graphitic material identified in the previous diamond drill holes.
The current drilling program was undertaken to delineate the hanging wall contact of the graphitic schist zone defined by the VTEM data last year and the full width of the zone bearing graphitic mineralisation at the Nicanda Hill prospect is still to be fully defined. Based on current drilling results is the graphite mineralisation zone is approximately 750m wide.
Drill hole GBNC005 has intersected multiple zones containing graphite for a cumulative drilled width of 220m . The entire intersection appears to be graphite bearing material other than several small intervals low or non-graphitic material. These thin intervals appear to be too narrow to pose any difficulties going forward (Figure 3).
The drill hole was terminated in graphite-bearing rocks at a total depth of 220m, as this was maximum depth capability of the RC drill rig.

Datum: WGS84 Zone 37S
Drilling results to date provide a strong correlation with the conductivity anomaly defined by the VTEM survey data. However, the eventual scale of the deposit may exceed the Company’s target expectations. These findings provide Triton with further confidence in the scale and continuity of graphite mineralization along the overall long strike potential of the Nicanda Hill prospect.
Based on the previous surface mapping and drilling the Company is confident that this newly-identified graphitic zone will extend substantially deeper beneath the surface of the Nicanda Hill prospect. Triton will endeavour to demonstrate this in the forthcoming diamond drilling program, which is now underway on the Nicanda Hill prospect.
These initial drilling results have now delineated that the graphite- zone on the Nicanda Hill prospect is at least 750m wide, over 200m deep and appears to have a strike length of over 5kms . These dimensions are consistent with the Company’s original interpretation of the VTEM data.
Drill core samples are currently being complied and finalised and will be transported to the SGS Laboratories in South Africa. Initial laboratory results from these RC drill samples are expected by the end of June 2014.

IMPLICATIONS
These initial drilling results confirm the world class potential of the Balama North project. It is anticipated that this drilling will provide the necessary data to estimate a Mineral Resource for this prospect by early 2015.
Should the drilling program confirm the continuity of the graphite mineralisation throughout the prospect, then Nicanda Hill has the potential to be a number of times larger than the Cobra Plains deposit and potential to become one of largest high grade graphite projects in the world .
The opportunities that such a large deposit of graphite could afford to Triton include the ability to high-grade certain parts within an encompassing body of graphitic mineralization, potentially allowing for very low strip ratios and possibility to customize product.
Triton is extremely optimistic of continued exploration success as the drilling program progresses during 2014 and is looking forward to providing further exploration updates to the market, as the information becomes available.

CLARIFICATION OF EXPLORATION TARGET INFORMATION
Triton provides the following information as clarification to the reporting of the Balama North exploration target disclosed in the Annual Report for the year ended 31 December 2013 and the Quarterly Activities Report for the quarter ended 31 March 2014.
Introduction
Triton estimates a combined exploration target range of approximately 730Mt to 1,200Mt for the three prospect areas, based on the known extents of the graphitic schist and a conservative assumed average grade range of 5% to 6% graphitic carbon (with no lower cut-off grade). On this basis, it is estimated that:
-
The Nicanda Hill prospect could potentially host between 480Mt and 800Mt of graphite carbon mineralisation;
-
The Charmers prospect is estimated to potentially host between 130Mt and 220Mt graphite carbon mineralisation; and
-
The Black Hills prospect is estimated to potentially host between 120Mt and 200Mt of graphite carbon mineralisation.
The potential quantity and grade of the Exploration Targets are conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further drilling and sampling will result in the estimation of a Mineral Resource.
Basis for Exploration Target
The Exploration Targets are based on previous exploration results obtained from the Balama North project.
Exploration Results
To date Triton has completed preliminary surface sampling with two trenches (219 channel samples) and rock chip sampling (7 samples) plus two diamond drill holes at the Nicanda Hill prospect (assay results were announced on 22 January 2014 and 19 February 2014). Exploration completed on the Black Hills and Charmers prospects comprises of mapping and rock chip samples (21 and 31 rock chip samples, respectively) taken on multiple traverses across the prospects and the assay results were announced to the market on 19 February 2014.

Extents of the known graphite schist units at the Cobra Plains, Nicanda Hill, Charmers and Black Hills prospects on the Balama North Project from which the combined Exploration Target of between 730Mt to 1,200Mt at an assumed average graphite carbon grade between 5% and 6% allowing for dilution of low grade or non-graphite bearing material. The potential quantity and grade of the Exploration Targets are conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further drilling and sampling will result in the estimation of a Mineral Resource. In February 2014, the Company announced the maiden Inferred Mineral Resource Estimate comprising 103 Million Tonnes (Mt) at an average grade of 5.52% graphitic carbon, containing 5.7Mt of graphitic carbon, at the Cobra Plain’s deposit at the Balama North project. This resource is classified as Inferred in accordance with the guidelines of The Australasian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code, 2012).Datum: WGS84 Zone 37S.
Basis of Grade and Tonnage Range Determination
The assumed average grade ranges (of 5% to 6% graphitic carbon) of the Exploration Targets attempt to conservatively factor for the level of internal dilution due to gneissic material and lower grade portions of the graphitic schist. Whist, the recently announced initial drilling, trenching and rock chip samples on Nicanda Hill returned graphite carbon grades of up to 28.6% graphitic carbon.
The average graphite carbon grades from these sampling programs are significantly higher than the assumed average grade range used for the exploration target estimation; being Nicanda Hill: 11.0% average unweighted graphite carbon (“AUGC”), Charmers: 9.8% average unweighted graphite carbon and Black Hills: 9.4% average unweighted graphite carbon (Figure 4)

Figure 5. Summary of 2013 exploration results for the Nicanda Hill prospect. The significant weighted average graphite intersections in the diamond drill holes and trenches correspond to the results presented in Table 1 and Table 3 and the rock chip values for the samples shown are listed in Table 2 of ASX release “Balama North Exploration Update” dated 19 February 2014. Datum: WGS84 Zone 37S
The extents of the exploration targets for the Nicanda Hill, Charmers and Black Hills prospects are modelled from field mapping of the graphite schist and Versatile Time domain Electromagnetic (VTEM) survey data recently acquired from previous license holders.
The surface outcrops of the graphitic schist units were projected down 150m to the 350mRL and wireframe models created at the average dip of the stratigraphy. Tonnages for each prospect were calculated by applying the Cobra Plains average density value of 2.7 t/m3.

ASX Media/Announcement 19 May 2014
The assumed proportions of graphitic schist material inside these models were estimated at 30% and 50% to derive the lower and upper conceptual tonnage ranges respectively. The image in Figure 1 shows the location and extents of each of the prospects.
Triton confirms the Exploration Target is based on the limited exploration activities completed to date and not proposed exploration programs. The Exploration Target is based on an assumption of the potential continuity and prospectivity of these exploration targets.
Proposed Exploration Activities Designed To Test Validity of the Exploration Target
Triton has designed a combined Reverse Circulation and Diamond drill program over the Nicanda Hill, Charmers and Black Hills prospects that will be undertaken during 2014, to confirm parts of the estimated Exploration Targets. It is anticipated that this drilling will provide the necessary data to estimate a Mineral Resource for parts of these three prospects before early 2015.

| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques | Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. The Cobra Plains deposit, part of the Balama North Project, was sampled using Reverse Circulation (RC) and diamond drill holes (DD) on a nominal 50 m x 500 m grid spacing. A total of 59 RC and 6 DD holes were drilled for 3,033 m and 1,066.14 m respectively. Holes were drilled -60 degrees towards grid east to optimally intersect the mineralised zones. All RC holes and 4 DD holes were drilled at Cobra Plains and 2 DD holes were drilled at Nicanda Hill (not part of this resource). Rock chip samples presented in Figure 4 were taken as 2.5kg grab samples on wide-spaced traverses over semi-continuous outcrop of graphite schist in the Black Hills and Charmers prospects. Samples included insitu and locally derived transported material. |
|
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used An initial wide spaced RC program on the Cobra Plains prospect was followed up by a second phase of infill RC and diamond drilling. Drillhole locations were picked up by a hand-held GPS (with nominal error of +- 5 metres) and reported using the World Geodetic System (1984 Spheroid and Datum; Zone 37 South). Downhole surveys of DD holes were measured using a Reflex ACTII downhole survey tool. Downhole surveys of RC holes were not taken. RC samples were collected by riffle splitter. Diamond core was used to obtain high quality samples that were logged for lithological, structural, geotechnical, density and other attributes. Rock chips reported were collected from the surface on wide-spaced traverses, but dependent on the presence of suitable sample material. The nature of the sample was determined to be residual or transported for each sample location |

| Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information Diamond core is generally HQ3 size, with PQ from surface to 36m (max), sampled on geological intervals (0.33 m to 2.7 m) and cut into half core to give sample weights under 3 kg. Samples were crushed, dried and composited prior to pulverisation (total prep) to produce a sub sample for analysis of Graphitic Carbon, Total Sulphur, and Total Carbon by Leco Combustion Infrared Detection. Composite samples were made from a 300g split of the coarse crush material of two consecutive samples of half core intervals that do not exceed 1.3m in core length each to yield a maximum of a 2.7m core length sample. Reverse circulation drilling was used to obtain 1m samples collected in a large bag and passed through a 3-tier riffle splitter to generate 1/8thsamples (approximately 3kg) contained in a labelled calico bag and the residual 7/8this retained at the drill site in the large bag. Where wet samples were encountered, the 3kg sample was collected using the tube (spear) sampling technique. The 3kg RC samples were pulverised (total prep) to produce a sub sample for assaying as above. In addition, select (approximately 20%) of RC samples were submitted for multi-element analysis (55 elements) by sodium peroxide fusion with an ICP-AES finish. Rock chip samples reported were prepared pulverized (total prep) to produce a sub sample for assaying as described above. The Company has taken all care to ensure no material containing carbon is incorporated into the samples. All samples are individually labelled and accompanied by sample tickets, and documented in two separate catalogues. |
||
| Drilling techniques | Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). RC drilling accounts for 93% of the current drilling at Cobra Plains using a reverse circulation drill rig, with a 5.5 inch size hammer. Hole depths range from 19 m to 139 m. Diamond drilling accounts for 7% of current drilling at Cobra Plains and comprises PQ to 32m, then HQ2 sized core. Pre-collar depths range from 3 m to 36 m and hole depths range from 145 m to 213 m. The core was orientated using an Ezi Mark II orientation tool with 72% of orientations rated as “good”. |
|
| Drill sample recovery | Method of recording and assessing core and chip sample recoveries and results assessed The condition and a qualitative estimate of RC sample recovery was determined through visual inspection of the 1m sample bags and recorded at the time of sampling. A hard copy and digital copy of the sampling log is maintained for data verification. Seventy-six percent (76%) of RC samples have recovery percentages logged in the database, of which 72% of samples had 100% sample recovery. Diamond core loss was established through standard core length measurements and drill length measurements and recoveries are logged and recorded in the database. Overall recoveries are >98% and there are no core loss issues or significant sample recovery problems. |
|
| Measures taken to maximise sample recovery and ensure representative nature of the samples Diamond core is reconstructed into continuous runs on an angle iron cradle for orientation marking. Depths are checked against the depth given on the core blocks and rod counts are routinely carried out by the drillers. RC samples were visually checked for recovery, moisture and contamination. Water entrainment into the sample is minimized through the use of additional high pressure air supply down hole. Wet samples are recorded as these generally have reduced sample recovery. |
||
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. The bulk of the Cobra Plains resource is defined by RC drilling, which has moderate recoveries. The style of mineralisation and the consistency of the mineralised intervals are considered to preclude any issue of sample bias due to material loss or gain. |
21
| Criteria | JORC Code explanation Commentary |
|---|---|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Geological logging at Cobra Plains was carried out on all diamond and RC holes for the full mineral assemblage that can be identified in hand specimen, in addition to texture, structure and estimates of graphite flake content and size. Geotechnical logging was carried out on all diamond drillholes for recovery, RQD and number of defects (per interval). Information on structure type, dip, dip direction, alpha angle, beta angle, texture, shape, roughness and fill material is stored in the structure table of the database. The mineralogy, textures and structures are recorded by the geologist into a digital data file at the drill site, which are regularly submitted to the Perth office for compilation and validation. |
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. Logging of diamond core and RC samples recorded lithology, mineralogy, mineralisation, structural (DDH only), weathering, colour and other features of the samples. Core was photographed in both dry and wet form. Photographs of rock chip sampling sites were not taken. Geological descriptions of the sample material are semi-quantitative for mineral assemblages and abundances. |
|
| The total length and percentage of the relevant intersections logged All drillholes were logged in full. Basic location, depositional regime and lithology was recorded for the rock chip samples. |
|
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. Diamond core was cut in half (HQ3) onsite using a brick saw. Half core samples generally 1 metre in core length were submitted to the lab. Each approximately 1m sample was crushed and a 300g split was taken. A composite sample representing an approximately 2m core length (length may vary due to geological contacts) was created by combining the crushed sample splits from two consecutive samples and pulverised for analysis. All samples are defined according to geological unit boundaries. |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. RC samples were collected on the rig using a riffle splitter and tube (spear) sampling tool. The majority of samples (¬70%) in mineralised zones were dry. Two metre composite samples were generated for drilled intersections with visible graphite (>0.5% graphite). The composite samples were produced by taking three spear sub samples from each 1 metre sample retained in the large sample bags (6 speared sub samples per 2m composite). The minimum composite sample size was 2.5kg. |
|
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. The sample preparation of diamond core follows industry best practice in sample preparation involving oven drying (105oC), coarse crushing of the core sample down to ~2 mm, split (500g) and pulverizing to a grind size of 85% passing 75 micron. The sample preparation for RC and rock chip samples is identical, without the coarse crush stage. |
|
| Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Field QC procedures involve the use of certified reference material as assay standards, along with blanks, and duplicates. Certified standards were inserted at a rate of 1 in 25 (DD, RC and rock chip samples), duplicates were inserted at a rate of 1 in 10 (DD) 1 in 24 (RC) and 1 in 32 (rock chips), and blanks were inserted at a rate of 1 in 90 (RC), 1 in 80 (DD) and not submitted with the rock chip samples. |
|
| Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. Chip samples are selected to weigh less than 3kg to ensure total preparation at the pulverisation stage. Field duplicates were taken on 2m composites for RC, using a riffle splitter. Rock chip samples were generally 500g in weight and may not be representatitive of the geological units sampled. |

| Whether sample sizes are appropriate to the grain size of the material being sampled. The drill sample sizes are considered to be appropriate to correctly represent mineralisation at Cobra Plains based on: the style of mineralisation, the thickness and consistency of the intersections, the sampling methodology and percent value assay ranges for the primary elements. The rock chip sample size is considered appropriate for the purpose of providing indicative grades. |
||
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. The analytical techniques used to analyse all samples for Graphitic Carbon, Total Sulphur, and Total Carbon was Leco Combustion Infrared Detection. In addition, selected drill samples were analysed for multi-element abundances using a fused disc digested in a four acid digest with ICP/OES or ICP/MS finish The acids used are hydrofluoric, nitric, perchloric and hydrochloric acids, suitable for silica based samples. The method approaches total dissolution of most minerals. |

| The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
||
| For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. No geophysical tools were used to determine any element concentrations used in either resource estimate. |
||
| No geophysical tools were used to determine any element concentrations used in either resource estimate. |
||
| Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. One certified reference material, analysed for Graphitic Carbon, Total Carbon and Total Sulphur, was inserted blindly. Six standards inserted with drill samples were outside three standard deviations for graphitic carbon and one was outside three standard deviations for total Sulphur indicating a problem in the sampling, a swap in the sample ordering at assaying, a problem with the calibration of the analytical machinery or a problem with the standard. Results also highlight a minor low bias during Phase 1 of drilling. All field blank samples returned values below the LOR for Graphitic Carbon, and above the LOR for Total Carbon and Total Sulphur. Both the RC and the diamond field duplicate datasets show strong correlation coefficients (0.92 for the diamond samples and 0.98 for RC samples), indicating good repeatability of grades between paired samples. The limited field duplicate and certified standards submitted with the rock chip samples were within two standard deviations of the expected values. Sample preparation checks for fineness were carried out by the laboratory as part of their internal procedures to ensure the grind size of 85% passing 75 micron was being attained. Laboratory QAQC involves the use of internal lab standards using certified reference material, blanks, and repeats as part of their in house procedures. Repeat analysis for samples reveals that precision of samples is within acceptable limits. A selection of the 1/8th riffle split samples will be submitted for umpire assays to SGS and an independent laboratory as independent checks of the assay results. Umpire laboratory campaigns using other laboratories is yet to be undertaken. |
||
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. Carl Young of Model Earth Geological Global Services, a consultant for Triton, has visually verified significant intersections in diamond core from Balama North. Optiro has not visually verified significant intersections in diamond core as part of the resource estimation process, but has checked core photos against the assay and geology logs for the diamond holes with provided core photos (TMBD0001: 0 m to EOH and TMBD0002: 0 m to 60 m). Core photos were not available for other diamond drillholes. |
|
| The use of twinned holes. Three RC holes were twinned with diamond holes to investigate sample bias related to the RC drill and sampling methods. The mineralisation zones within the holes show a reasonable correlation. Though the grade graphs suggest that the diamond holes are reporting higher graphitic carbon grades than the RC holes. |

| Discuss any adjustment to assay data. No adjustments or calibrations were made to any assay data. A total of 72 drillhole intervals, of a variety of lithologies, from within the mineralisation wireframes have not been sampled. Assay values were assigned by Optiro to the missing drillhole intervals prior to resource estimation by reviewing assay statistics by lithology type. |
||
| Location of data points | Accuracy and quality of surveys used to locate drillholes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Collar locations for all holes and rock chip samples were surveyed by hand-held GPS (nominal error of 5 metres). Drill holes were oriented at the collar using sighting pegs installed with the use of a magnetic compass and GPS. The dip of all RC holes is recorded for the collar only and no downhole surveys were taken. The dip and azimuth of all DD holes is measured by Mitchell Drilling using a Reflex ACTII downhole survey tool. Downhole surveys used single shot readings during drilling at approximately every 25 to 30 m. Stated accuracy is +-10. Nine downhole survey measurements have been coded by Triton as ‘Priority 2’. These have been excluded from the resource estimate. |

||
| Data spacing and distribution | Data spacing for reporting of Exploration Results. The nominal drillhole spacing is 500 m (grid northing) by 50 m (grid easting) in the core of the deposit. Rock chip sample spacing was nominally 10 metres but dependent on availability of outcrop or subcrop. |
|
| Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. The mineralised domains have demonstrated sufficient continuity in geological and grade continuity to support the definition of Inferred Mineral Resources, and the classifications applied under the 2012 JORC Code. |

| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. The deposit is drilled towards the south east (mag) at angles varying from -550and -600to intersect the mineralised zones approximately orthogonal to the interpreted dip and strike of the geological boundaries. There is no known association between graphite abundance or quality and structure at this stage. |
|

Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The Cobra Plains Prospect and the Nicanda Hill Prospect are located wholly within Exploration Licences EL5365 and EL5966 respectively within the Cabo Delgado Province of Mozambique. Both licences are held by Grafex Limitada (Grafex), a Mozambican registered company. Triton Minerals entered into a Joint Venture (JV) agreement in December 2012 with Grafex to earn up to an 80% interest in Grafex’s portfolio of graphite projects. In late 2013 Triton increased their holding in the projects to 60% by taking a direct equity interest in Grafex. EL5365 is valid until 29/10/2017 and EL5966 is valid until 19/06/2018. |

| Exploration done by other parties | Acknowledgment and appraisal of exploration by other parties. No previous systematic exploration has been undertaken at the Cobra Plains or the Nicanda Hill Prospects of the Balama North Project. Recently the Company has been made aware of an airborne electromagnetic survey that covers Licences 5966 and 5365. Efforts are underway to acquire this dataset from the previous licence holders.Small scale exploratory pits dug for ruby exploration were recently identified. |
|
| Geology | Deposit type, geological setting and style of mineralisation. The Cobra Plains graphite deposit is hosted within Neoproterozoic rocks of the Xixano Complex in north-eastern Mozambique. The Xixano complex is composed dominantly of mafic to intermediate orthogneiss with intercalations of paragneiss, meta-arkose, quartzite, tremolite-rich marble and graphitic schist. Graphite mineralisation is hosted within fine grained graphitic schists underlain and overlain by felsic gneiss rock types. Mineralisation occurs as series of multiple stacked tabular northeast-southwest striking lodes moderately dipping to the northwest. Graphite mineralisation outcrops at surfaces and has been intersection at depths of up to 130 m below surface. Graphitic mineralisation is interpreted to be continuous between the Cobra Plains and the Nicanda Hill Prospects of the Balama North Deposit. Occurrences of vanadium mineralisation noted in the samples is thought to be associated with roscoelite schists. |

| Drill hole Information | A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: easting and northing of the drill hole collar elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar dip and azimuth of the hole down hole length and interception depth hole length. Refer toAppendix 3 – Table 1of ASX release dated 19 February 2014. |
|
| Data aggregation methods | In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. No top-cuts have been applied. |
26
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. Significant intercepts reported were calculated as core-length weighted assay intercepts. Narrow intervals within the calculated intercepts for which no sample was taken due to the lack of graphite are assigned a value of 0% graphite carbon during the calculation of the weighted assay intercept values. A cut off value of 2% graphite carbon was applied in calculating the weighted assay intercepts. |
||
| The assumptions used for any reporting of metal equivalent values should be clearly stated. No metal equivalent values are used for reporting exploration results. |
||
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). The Cobra Plains deposit is moderately northwest dipping. Drillholes are inclined between -550and -600to the southeast to intersect the mineralised zones approximately orthogonal to the interpreted dip and strike of the geological boundaries. Additional drillholes are required to establish the graphite grade strike and dip continuity to a higher confidence level at depth. The rock chip data is not appropriate for determining the width of graphite mineralised lodes. |
|
| Diagrams | Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. Refer to Figure 2 in the body of the text. |
|
| Balanced reporting | Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. All drill results for Cobra Plains deposit are reported. No further assays are outstanding. |
|
| Other substantive exploration data | Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. Selected core samples were measured for their bulk density, which in the Cobra Plains deposit ranged from 2.04 g/cm3to 3.42 g/cm3. Multi element assaying was conducted on selected RC chip samples. Geotechnical logging was carried out on all diamond drillholes for recovery, RQD and number of defects (per interval). Information on structure type, dip, dip direction, alpha angle, beta angle, texture, shape, roughness and fill material is stored in the structure table of the database. Surface trenching was conducted at Nicanda Hill and surface rock chip sampling was undertaken at Nicanda Hill and Cobra Plains, which indicates graphite mineralisation extends for more than 8 km along the Nicanda Hill and Cobra Plains Prospects. Rock chip samples submitted for petrographic analysis by SGS showed that 30% of graphite flakes were in the range of 0.5 mm to 1 mm in length. Regional scale mapping has been carried out in the area to identify outcrop of graphitic material. This mapping is ongoing and will be reported with the surface sampling that has recently completed in some areas. |
|
| Further work | The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive Further drill testing using reverse circulation and diamond drilling is planned at Balama North to determine the grade continuity and width of the identified graphitic units. Exploration activities resumed after the end of the wet season in April 2014. |

JORC Table 1 - Section 1 Sampling Techniques and Data
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques | Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. The Nicanda Hill prospect is located on the Balama North Project. The drill results included in this report were obtained using Reverse Circulation (RC) drilling. The nominal hole spacing of the current program is 100m x 400m. Diamond drill holes will be interspersed within the planned drill grid to provide qualitative information on structure and physical properties of the mineralization. Holes were drilled -60 degrees towards UTM south east to optimally intersect the mineralised zones. |
|
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used Drillhole locations were picked up by differential GPS (with nominal error of +- 0.3 metres) and reported using the World Geodetic System (1984 Spheroid and Datum; Zone 37 South). Downhole surveys of the RC holes were measured using a Reflex ACTII downhole survey tool. The collar surveys were validated with the use of a compass and inclinometer. RC samples have been collected using a riffle splitter to obtain a 1/8thsample, which will be split and combined to produce 2m composite samples. Efforts are taken to keep the sample material dry during drilling to avoid any bias. Wet samples are recorded and the results of these are monitored for bias. |
||
| Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information No sample assay results are reported in this announcement. Nonetheless the practices employed for the samples obtained and due for shipment to the lab is described below. Reverse circulation drilling was used to obtain 1m samples collected in a large bag and passed through a 3-tier riffle splitter to generate 1/8thsamples (approximately 3kg) contained in a labelled calico bag and the residual 7/8this retained at the drill site in the large bag. Where wet samples were encountered, the 3kg sample was collected using the tube (spear) sampling technique. The 3kg RC samples will be split using a 50:50 splitter to and one half is to be combined with the half split of the consecutive 1m sample, producing a 2m composite sample. This sample will be pulverised (total prep) by the lab to produce a sub sample for assaying as above. In addition, select RC samples will be submitted for multi-element analysis (55 elements) by sodium peroxide fusion with an ICP-AES finish. |
||
| Drilling techniques | Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc). |
|
| The reverse circulation drill rig uses a 5.5 inch size hammer. Hole depths range up to a maximum depth of 222m (rig capability limit). |
||
| Drill sample recovery | Method of recording and assessing core and chip sample recoveries and results assessed The condition and a qualitative estimate of RC sample recovery was determined through visual inspection of the 1m sample bags and recorded at the time of sampling. A hard copy and digital copy of the sampling log is maintained for data verification. . |
|
| Measures taken to maximise sample recovery and ensure representative nature of the samples Diamond core is reconstructed into continuous runs on an angle iron cradle for orientation marking. Depths are checked against the depth given on the core blocks and rod counts are routinely carried out by the drillers. RC samples were visually checked for recovery, moisture and contamination. Water entrainment into the sample is minimized through the use of additional high pressure air supply down hole. Wet samples are recorded as these generally have reduced sample recovery. |
28
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. Comparisons of RC and Diamond drill sample material on the neighbouring Cobra Plains deposit showed no statistically significant bias associated with the RC drill technique. Extensive diamond drilling will be carried out as part of this program to confirm the QAQC paramters of the sample material. |
||
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Geological logging is carried out on holes for the full mineral assemblage that can be identified in hand specimen, in addition to texture, structure and estimates of graphite flake content and size. Geotechnical logging will be carried out on all diamond drillholes for recovery, RQD and number of defects (per interval). Information on structure type, dip, dip direction, alpha angle, beta angle, texture, shape, roughness and fill material is stored in the structure table of the database. The mineralogy, textures and structures are recorded by the geologist into a digital data file at the drill site, which are regularly submitted to the Perth office for compilation and validation. |
|
| Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. Logging of RC samples and diamond core records lithology, mineralogy, mineralisation, weathering, colour and other features of the samples. Chip trays and diamond core are photographed. Geological descriptions of the sample material are semi-quantitative for mineral assemblages and abundances. |
||
| The total length and percentage of the relevant intersections logged | All drillholes are logged in full. | |
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. Diamond core is be cut in half (HQ3) onsite using a brick saw. Half core samples generally 1 metre in core length will be submitted to the lab. Each approximately 1m sample will be crushed and a 300g split taken. A composite sample representing an approximately 2m core length (length may vary due to geological contacts) will be created by combining the crushed sample splits from two consecutive samples and pulverised for analysis. All samples are defined according to geological unit boundaries. |
|
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. RC samples are collected on the rig using two riffle splitters. The majority of samples are dry. Two metre composite samples are generated by taking the 1m samples from the drill cyclone into a large bag and passing this material through a 3-tier riffle splitter to generate 1/8thsamples (approximately 3kg) contained in a labelled calico bag and the residual 7/8this retained at the drill site in the large bag. Where wet samples are encountered, the 3kg sample is collected using the tube (spear) sampling technique once the sample has partially dried. The 3kg RC samples will be split using a 50:50 splitter to and one half is to be combined with the half split of the consecutive 1m sample, producing a 2m composite sample. were generated for drilled intersections with visible graphite (>0.5% graphite). The composite samples will be generated were produced by taking three spear sub samples from each 1 metre sample retained in the large sample bags (6 speared sub samples per 2m composite). The minimum composite sample size was 2.5kg. |
||
| For all sample types, the nature, quality and appropriateness of the sample preparation technique. The sample preparation of the diamond core samples follows industry best practice in sample preparation involving oven drying (105oC), coarse crushing of the diamond core sample down to ~2 mm, split (500g) and pulverizing to a grind size of 85% passing 75 micron. The sample preparation for RC samples is identical, without the coarse crush stage. |
||
| Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. Field QC procedures involve the use of two certified reference material assay standards, along with certified zblanks, and insertion of field duplicates. Certified standards are inserted at a rate of 1 in 25 (DD, RC and rock chip samples), duplicates are inserted at a rate of 1 in 20 and blanks are inserted at a rate of 1 in 50. |
||
| Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. Field duplicates are taken on 2m composites for RC, using a riffle splitter. Field duplicates are taken on quarter diamond core |

| Whether sample sizes are appropriate to the grain size of the material being sampled. The drill sample sizes are considered to be appropriate to correctly represent mineralisation at the Balama North project based on the style of mineralisation, the thickness and consistency of the intersections, the sampling methodology and percent value assay ranges for the primary elements. |
||
| Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. The analytical techniques used to analyse all samples for Graphitic Carbon, Total Sulphur, and Total Carbon on a Leco Combustion Infrared Detection instrument. In addition, selected drill samples are analysed for multi-element abundances using a fused disc digested in a four acid digest with ICP/OES or ICP/MS finish The acids used are hydrofluoric, nitric, perchloric and hydrochloric acids, suitable for silica based samples. The method approaches total dissolution of most minerals. |

||
| No geophysical tools were used to determine any element concentrations. | ||
| Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. The field duplicate datasets for all of the diamond and RC holes drilled in 2013 showed strong correlation coefficients (0.92 for the diamond samples and 0.98 for RC samples), indicating good repeatability of grades between paired samples. Sample preparation checks for fineness will be carried out by the laboratory as part of their internal procedures to ensure the grind size of 85% passing 75 micron was being attained. Laboratory QAQC involves the use of internal lab standards using certified reference material, blanks, and repeats as part of their in house procedures. Repeat analysis for samples reveals that precision of samples is within acceptable limits. A selection of the 1/8th riffle split samples will be submitted for umpire assays to SGS and an independent laboratory as independent checks of the assay results. Umpire laboratory campaigns using other laboratories is yet to be undertaken. |
||
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. Carl Young of Model Earth Geological Global Services, a consultant for Triton, has visually verified the geological observations of the six RC drill holes drilled at the Nicanda Hill prospect presented in this announcement |
|
| The use of twinned holes. Three RC holes were twinned with diamond holes at the neighbouring Cobra Plains deposit in 2013 to investigate sample bias related to the RC drill and sampling methods. The mineralisation zones within the holes show a reasonable correlation. Though the grade graphs suggest that the diamond holes are reporting higher graphitic carbon grades than the RC holes. |

| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Sample information is recorded at the time of sampling in electronic and hard copy form. Assay data is received from SGS in electronic form and compiled into the Company’s digital database. Secured electronic print files have been provided to the Company for verification purposes. |

Regional scale mapping has been carried out in the area to identify outcrop of graphitic material. This mapping is ongoing. |

| Further work | The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive Further drill testing using reverse circulation and diamond drilling is planned on the Nicanda Hill prospect, on the Balama North project to determine the grade continuity and width of the identified graphitic units. Exploration activities resumed in April 2014. |
