Buxton Resources Limited (ASX: BUX) is pleased to report that all assays for the 2017 drill program at Double Magic have been received. Several intersections have returned grades above 1% Ni. Of the 26 holes drilled, 25 intersected magmatic Ni-Cu sulphides confirming a much-increased extent of Ni-Cu sulphide mineralisation at Merlin. A very large, complex mineralised magmatic system, still open in all directions, continues to be discovered within the Ruins Dolerite.

Fieldwork during 2017 has substantially expanded the known extent of continuous sulphide mineralisation along strike (~1,500m) and down-dip (>600m). A second possible conduit or feeder, with brecciated massive sulphide (DMDD0014) indicating high-energy emplacement, has now been located 450 metres south-east of the 2015 discovery at Conductor D.
A possible high-grade trend has been identified within the broader magmatic Ni-Cu sulphide system (Figures 1-4), providing one obvious target for future drilling. Higher-grade mineralisation along this trend includes stringer or net-textured sulphides, massive sulphides, and/or brecciated massive sulphide. This trend appears open to the south and south-west as indicated by recent down-hole transient electromagnetic (DHTEM) results, which are supported by geological observations in up-dip holes.

The presence of brecciated massive sulphides is particularly encouraging, indicating forceful injection or re-working of massive sulphides in a high-energy magmatic environment, something usually considered an essential part of the processes involved in forming large, high-grade magmatic sulphide deposits. This discovery of brecciated sulphides at Merlin is therefore a very strong confirmation of the genetic model, and consequent prospectivity, of the Merlin mineralised system as it demonstrates the system had the capability to segregate and deposit high-grade massive sulphides.

A plan of drill hole locations is included as Figure 2 and drill hole details listed in Table 2. A cross-section through the east of the Merlin Prospect shows the location of brecciated massive sulphides (Figure 4). Table 1 lists all 2017 intersections above 0.25% Ni, greater than 2m in length (with up to 2m of subgrade).

Geophysics
DHTEM surveying of the last hole of the 2017 program, DMDD0014, indicated the hole successfully intercepted the modelled conductor, which was then refined as being approximately 150mx50m in size and probably extending to the south or south-west.
The very high in-hole response amplitude in DMDD0014 has masked any more distant responses, including from any other electrically disconnected conductors within the same broad geological horizon. This means that additional conductors in the area may not have been detected by any EM completed to date. Step-out holes drilled specifically to provide platforms for DHTEM, as well as more traditional holes testing geological targets, may be required to effectively explore this trend.

Figure 5 – Cross-section close-up of DMDD0014 and DMDD0012 showing modelled high conductance DHTEM plate. Conductor is open to the south and southwest. Note primary net-textured Ni-Cu mineralisation in DMDD0014 above the DHTEM plate.
Geophysical assessment and reporting is still underway. Apart from routine gyro surveying, holes were down-hole logged for TEM, conductivity, magnetic susceptibility, and natural gamma. Six selected holes were also logged for gamma-gamma (density), and down-hole Induced Polarisation (DHIP). Benchtop petrophysical testwork on core from DMDD0005 will be completed in coming weeks to assist interpretation of DHIP logging results, pursuant to better understanding the nature of the large IP anomaly identified in 2016.
As the excellent intercepts from DMDD0014, DMDD0012 and DMRC0038 came towards the end of the funded 2017 work program, Buxton elected to suspend drilling until all data has been received and thoroughly assessed. With large fires in the area and the next wet season now imminent, further drilling this calendar year is not feasible.
Buxton Resources acknowledges the support of the Western Australian Department of Mines and Petroleum for their contribution via the WA Exploration Incentive Scheme and has applied for further assistance for the 2018 drill programme.
Buxton looks forward to updating investors as work progresses on this challenging but exciting project.

JORC Table: Section 1 – Sampling Techniques and Data
==> picture [228 x 71] intentionally omitted <==
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques | Nature and quality of sampling (eg 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. |
Early stage exploration drilling at the Double Magic project has been undertaken utilizing a Reverse Circulation Percussion (RC) rig, and an HQ diamond core wireline rig equipped with core orientation equipment. The drill-hole locations are picked up by handheld GPS. Previous drill programs holes have been surveyed by licensed surveyors with DGPS. Sampling was carried out under Buxton protocols and QAQC procedures are per industry best practice. RC drilling was sampled on 1m intervals. A rig mounted cyclone and cone splitter was used to provide a bulk sample and a representative split sample for assay. Core sample lengths vary up to 1.67 metres, quarter HQ core submitted for analysis. Samples have been submitted to Intertek Genalysis in Perth for analysis. A standard dry, crush and pulverize was followed by a four-acid digestion finished with ICP- MS for a suite of 48 elements. |
| Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. |
||
| 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 (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information. |
||
| Drilling techniques | Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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 2017 drilling drill programs are being drilled By Core Drilling. Reverse Circulation drilling is using a Schramm T685 drilling rig with Auxiliary and Booster using a 150mm face hammer. Diamond drilling is using an EDM 2000 truck mounted rig, drilling HQ core from surface. RC hole DMRC0035 was extended with NQ core. All core orientated using a TruCore orientation device on each drill run. All drill holes have been by downhole gyro to determine accurate hole trajectories. |
| Drill sample recovery | Method of recording and assessing core and chip sample recoveries and results assessed. |
The RC ‘s sample recovery and moisture are routinely recorded. All samples show good recovery and are dry. It is not believed that any bias has occurred due to loss or gain of sample. All core was measured on-site, recoveries calculated and reconciled with driller’s plods. |
| Measures taken to maximise sample recovery and ensure representative nature of the samples. |
||
| 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. |
||
| 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. |
All drill holes are geologically logged in real time by qualified and experienced geologists, recording relevant data to a set template. All logging included lithological features, mineral assemblages and estimated mineralisation percentages. All data was codified to a set of company code systems. All core is orientated, RQD logged, all structural data measured and recorded. All chips and core are photographed. |
| Whether logging is qualitative or quantitative in nature. _Core(or costean, channel, etc) photography. _ |
||
| The total length and percentage of the relevant intersections logged. |
||
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. |
All RC 1m intervals were split with a rig mounted cone splitter. All HQ core was sawn at a constant angle to orientation markings, sampled to geological boundaries, up to a maximum of 1.67 metres in length. Quarter core submitted for assay. Sample preparation is consistent with industry best practice. Field QC procedures involved the use of certified reference material assay standards, blanks and duplicates for company QC measures, and laboratory standards, replicate assaying and barren washes for laboratory QC measures. The insertion rate of each of these QAQC measures averaged 1:20. The sample size is deemed appropriate for the material and analysis method. |
| If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. |
||
| For all sample types, the nature, quality and appropriateness of the samplepreparation technique. |
||
| Quality control procedures adopted for all sub-sampling stages to maximise representivity of 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. |
||
| Whether sample sizes are appropriate to the grain size of the material being sampled. |
| 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 exploration samples will be analysed at Intertek Genalysis in Perth, Australia. Sample preparation included drying, crushing, splitting and pulverizing. A four acid digest followed by a 48 element MS. Previous drill used a 4 acid digest with an OE finish and a 25 g fire assay for Pt and Pd. Metallurgical flotation testing was carried out by ALS on three 12 kg samples on ¼ and or ½ core from the 2015 drilling. Core was crushed and ground to 106um with natural pH with excess collector Sodium Ethyl Xanthate (SEX) and A3477 with MIBC (frother) added as froth stability required. The laboratories procedures are considered to be appropriate for reporting according to industry best practice. |
| 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. |
Not applicable. | |
| Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
Not applicable. | |
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. |
Significant mineralisation has been verified by consultants and alternative company personnel. |
| The use of twinned holes. | Two RC holes for the 2015 drill program (DMRC0003 and 17) have been twinned by HQ diamond core holes DMDD0001 and 2 respectively, confirming mineralisation in both cases. Core has been logged but not sawn for samplingasgeological work is ongoing. |
|
| Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. |
All data is collected initially on paper and handheld GPS. This data is hand entered to spread sheets and validated by Company geologists. This data is then imported into the company database and extra validation is carried out. Physical data sheets are stored at the company office. Digital data is securelyarchived on and off-site. |
|
| Discuss any adjustment to assay data. | No adjustments to assay data have been made. | |
| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. |
Handheld GPS (+/-5m) as well as reference to topographical and remote sensing data. Drillhole collars from the 2015 drill program were pickup by licensed surveyor. |
| Specification of thegrid system used. | MGA51(GDA94). | |
| Quality and adequacy of topographic control. | A DEM (digital terrain model) was created from the altimeter data from the aerial magnetic survey and is deemed sufficient for this stage of exploration. |
|
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. | The current drill program is reconnaissance and step out from the 2015 drilling program, spacing is deemed appropriate for this stage of exploration. Not applicable – No Mineral Resource or Ore Reserve calculations have been performed. The 2015 drilling had some RC composite samples taken in non mineralised material into 2 or 4 metre composites from one metre bags using a spear. No sample compositing has taken place in the 2017 drilling to date. Metallurgical samples were composite samples from drill core. |
| 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 estimationprocedure(s) and classifications applied. |
||
| Whether sample compositing has been applied. | ||
| 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. |
Information from orientated core indicates that drillhole orientation is appropriate for disseminated and massive matrix mineralisation. All mineralised intervals are down hole intervals, not true width. |
| If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
||
| Sample security | The measures taken to ensure sample security. | Samples were packaged and stored in secure storage from the time of gathering through to submission. Laboratorybestpractice methods were employed bythe |
| laboratory upon receipt. Returned pulps will be stored at a secure company warehouse. No audits of the sampling techniques or data were carried out due to the early stage of exploration. It is considered by the Company that industry best practice methods have been employed at all stages of the exploration. |

Data used during the appraisal of the Double Magic Project (previously known as the Alexander Creek Project, Clara Hills, Jack’s Hill, Limestone Springs & Maura’s Reward) has been collected by numerous exploration parties, including Alexander Creek Pty Ltd, Victory Mines Limited (ASX:VIC), Proto Resources and Investments Limited (ASX:PRW), and Ram Resources Limited (ASX:RMR). All geophysical data has been independently reviewed by Southern Geoscience Consultants. Any historical data presented has been previously reported under JORC 2004 and there has been no material change. |
| Geology | Deposit type, geological setting and style of mineralisation. |
The Project area lies within the Palaeoproterozoic Hooper Province of the King Leopold Orogen in the Kimberley region of Western Australia. The geology of the Project is characterized by mica schists of the Marboo Formation which are intruded by thick sills of the Ruins Dolerite. The Ruins Dolerite is a medium- to fine-grained mafic-ultramafic intrusive that is host to the known nickel-copper sulphide mineralisation. This mineralisation is interpreted to represent primary orthomagmatic sulphide mineralisation, however there appears to be significant re-working and alteration of the mineralisation in places (in particular at the Jack’s Hill Gossan where the mineralisation is dominated by copper carbonates and contains limited nickel). Importantly the gossan at Jack’s Hill does not have an electromagnetic (EM) signature, whereas the EM targets tested to date all appear to be due to nickel and copper enriched sulphide mineralisation. |
| 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: |
See Tables in body of release. |
| o_easting and northing of the drill hole collar_ | ||
| o_elevation or RL (Reduced Level – elevation above sea_ level in metres) of the drill hole collar |
||
| o_dip and azimuth of the hole_ | ||
| o_down hole length and interception depth_ | ||
| o_hole length_ | ||
| If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
| Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. |
No weighting, truncations, aggregates or metal equivalents were used. |
| 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. |
||
| The assumptions used for any reporting of metal equivalent values should be clearly stated. |
||
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. |
The relationship between the true mineralisation width and intercept length is not known at this early stage of drilling, however true width of the intercepts in most holes is interpreted to be less than intercept length. |
| 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 (eg ‘down hole length, true width not known’). |
||
| 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 figures/tables in body of release. |
| 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 currently available exploration results have been reported. |
| 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. |

| Further work | The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step- out drilling). |
See text in body of release. |
| Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
See modelled conductors in Figures within the text of this report. Additional zones of interest may be established based on geological information (such as drilling or downhole data). Regionally, the extensive land package containing significant exposure of the nickeliferous host lithology the Ruin’s Dolerite are of exploration interest. |
