CARLOW CASTLE GOLD-COPPER-COBALT RESOURCE GROWS BY 71% TO 7.7Mt 1
Inferred resource of 7.7Mt @ 1.06 g/t Au, 0.51% Cu and 0.08% Co for 260k Oz Au, 38kt Cu and 5,900t of Co
Artemis Resources Limited (“Artemis” or “the Company”) (ASX:ARV, Frankfurt: ATY, US OTCQB :ARTTF) is pleased to announce a significant increase in the Mineral Resources reported in accordance with the JORC Code (2012) at its 100% owned Carlow Castle Project (EL 47/1797) in the West Pilbara region of Western Australia.
Since the previous resource announcement for Carlow Castle (19 January 2018), Artemis have completed additional drilling that added to the resources, mainly in previously undrilled sections along strike and near the central area of the Carlow Castle line. In total 12 diamond drill holes for 1,504.6 m and 108 Reverse Circulation (RC) drill holes for 15,882 m were drilled since the previous announcement.
A summary of the Carlow resource estimate is tabulated below ( Table 1 ). The entire resource is classified as Inferred Mineral Resources totalling 7.7M tonnes at 1.06 g/t Au, 0.51% Cu and 0.08% Co. The resource is reported for material using a lower cut off grade of 0.3g/t Au. High grades have been capped (top cut) for gold, copper and cobalt. The top cut varies dependent on the grade domain, these values are tabulated in Table 4 .

Artemis Chief Executive Officer Wayne Bramwell commented;
“The 2018 Carlow Castle Au-Cu-Co drilling programme has significantly increased the inferred resource to 7.7Mt. The growth in tonnage, in conjunction with our preliminary metallurgical programme confirming Carlow Castle’s amenability to low cost processing technology now builds a platform to advance Carlow Castle in a systematic manner.
The next round of diamond drilling will focus on improving the structural understanding of the resource and better inform proposed extensional drilling.”
1 The Company notes that it has materially updated its Mineral Resource since the last estimate provided to the market on 31 January 2018. The upgrade its based on newly acquired information set out in this announcement.

CARLOW CASTLE Au-Cu-Co PROJECT RESOURCE SUMMARY
The Carlow Castle Au-Cu-Co Project is in the West Pilbara region of Western Australia, ≈45 km by road east of the city of Karratha (Figure 1). Access is via the Northwest Coastal Highway and then by the unsealed Cheratta road which passes through the Project area. Carlow Castle is on the granted exploration license E47/1797 held by KML No 2 Pty Ltd, a 100% owned subsidiary of Artemis Resources and is ≈35 km from Artemis’ 100% owned Radio Hill Processing Plant.

Figure 1: Carlow Castle Project Location Map.
Artemis recently completed reverse circulation drill (RC) aimed at expanding the known resource along strike, infilling the drill pattern to 40 m by 20 m and testing depth extent of the ore zones. A total of 189 RC drill holes and 12 diamond drill holes for 24,754.6 m has been completed by Artemis since March 2017. Additional historical drilling (mainly RC) was completed by others and as this is not to JORC 2012 standard, has not been included in the current estimate.
GEOLOGY AND GEOLOGICAL INTERPRETATION
The Carlow Castle deposit occurs in 2 zones being Carlow Castle and Quod Est with these structurally controlled mineralised zones occurring almost at right angles to each other.
▪ Carlow Castle Zone
The Carlow Castle portion strikes east-west, being fault terminated at each end.

Drill definition has been completed over the 1000 m strike length which has a flattened sinusoidal form. At the western end mineralisation dips steeply north, at the eastern end the mineralisation dips steeply south.
Mineralisation in Carlow Castle has been shown to extend to at least 250 m below surface.
- Quod Est Zone
The Quod Est portion strikes approximately north-south dipping steeply east with a strike length of about 200 m and is fault terminated to the north and potentially at depth. The RC drilling has identified additional mineralised zones to the east of Quod Est; at this stage these are of very limited extent but given the prevalence of historic workings in the area, potential exists to expand these lodes.
The structurally controlled ore zones at Carlow consist of chalcopyrite, chalcocite, cobaltite, pyrite and gold in constantly variable amounts within shears and brecciated zones in chloritized basalt. Minor tellurobismuthite, hessite and uraninite also occur.

SAMPLING AND ASSAY
There are no references available that describe the sampling methods used by previous operators at Carlow Castle prior to Artemis drilling in 2017, as such all historical data has been discarded.
▪ Artemis Drilling, Sampling and Assay
The RC drilling was completed on a nominal 20 m x 40 m grid spacing using a truck-mounted Schramm 685 RC drilling rig with a 5¼ inch (13 cm) diameter face sampling hammer. The drill chips were split using a rig mounted cyclone and static cone splitter over one metre intervals to obtain 2 to 4 kilogram sub-samples to be dispatched to the laboratory for multi-element analysis including Au, Cu, Co, As, Ag, and S.
A field geologist supervised all the drilling and logged the drill samples for lithologies, weathering, alteration and mineralisation. Reference samples were collected for each metre and stored in chip trays for future reference.
Sample recoveries were recorded by the geologist in the field during logging and sampling. If poor sample recoveries were encountered during drilling, the supervising geologist and driller endeavoured to rectify the problem to ensure maximum sample recovery.
The majority of samples were dry. Where wet sample was encountered, the cleanliness of the cyclone and splitter were closely monitored by the supervising geologist and maintained to a satisfactory level to avoid contamination and ensure representative samples were being collected.
The down-hole intervals logged by the geologist as being mineralised or showing significant alteration were sampled and assayed at 1 m intervals. In only the second phase of drilling were samples composited, holes ARC036 to ARC081. All unmineralized intervals (based on the field portable XRF readings for Cu, Co and As) were composited and assayed over 3 m intervals. Mineralized intervals based on the field XRF readings were assayed in 1 m intervals.

MEDIA AND PRESS RELEASE ASX: ARV | OTCQB: ARTFF | Frankfurt: ATY
==> picture [43 x 39] intentionally omitted <==
If a 3 m composite returned assays above normal background levels these intervals were re-sampled and assayed over 1 m intervals.
Field duplicates in the form of a second split from the static cone splitter were taken every 20[th] sample with standard reference samples and blanks inserted on a rotational basis every 20[th] sample to monitor the quality control of the sampling and chemical analyses.
The HQ3 diamond drilling was completed using a truck mounted Evolution FH3000 Diamond Drill. The core was logged by the site geologist with core recoveries, lithologies, alteration type and intensity, mineralogy’s and fractures/structures recorded. All the diamond core was cut by trained technicians along the long-axis using a diamond saw between intervals marked up by the geologist. The sampling intervals were nominally 1.0 m adjusted to match lithological/mineralisation boundaries.
Topography and Surveying
A topographic DTM was prepared using photogrammetry (0.035 m resolution) in January 2018.
A hand-held GPS was used to position the drill hole collars prior to drilling. The collars of all the completed holes were subsequently picked up with DGPS with an accuracy of within 1 cm. The grid system used for all Artemis drilling is GDA94 (MGA 94 Zone 50).
SAMPLE SECURITY, PREPARATION, AND ANALYSIS
In the first two RC drilling phases five samples were bagged into poly-weave sacks, labelled, then loaded on a vehicle and taken to the transport depot where they were shrink wrapped to pallets and delivered directly to the laboratory.
In the second two RC drilling phases five samples were bagged into poly-weave sacks and then loaded directly into a bulk bag, each hole was placed in a separate bag, at the end of each day a Hiab equipped truck would collect the labelled bulk bags and deliver direct to the transport depot. These were loaded directly onto the truck and delivered direct to the laboratory. Each bulk bag or hole had a separate sample dispatch and became a separate analytical batch in the laboratory.
The Artemis drill samples were submitted to the laboratory for multi-element analysis including: Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, La, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Sr, Th, Ti, Tl, U, V, W, Zn. All the analyses were carried out by an independent laboratory, ALS Global (Perth) - 26 Rigali Way, Wangara Western Australia 6065.
After the samples were dried, samples received at the lab weighing more than 3 kg were riffle split. The samples were then pulverised to 95% passing 75 microns.
-
The gold was analysed with the 50 gram Fire Assay (Au-AA26) with ICP finish technique;
-
Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, K, La, Mg, Mn, Mo, Na, Ni, P, Pb, S, Sb, Sc, Sr, Th, Ti, Tl, U, V, W, Zn were routinely analysed using Acid Digest ICP-AES Finish (ME-ICP61);
-
Higher ore grade samples were analysed with 4 Acid Digest ICP-AES Finish (MEOG62);
All core samples were processed through the same regime with standard reference samples inserted every 20[th] sample, field duplicates were not included.

CRITERIA USED FOR CLASSIFICATION
Artemis has classified the Mineral Resource as an inferred resource on the following basis:
-
the resource is drilled on a relatively close spaced pattern, nominally 40m line spacing and a nominal 25m down dip spacing.
-
the majority of the drilling is RC drilling.
-
the mineralisation is interpreted as being predominantly structurally controlled and occurs as veins, stockworks and breccias.
-
The limited amount of diamond drilling has meant the structural interpretation relies heavily on RC drilling supported by limited mapping and interpretation of geophysical data. This means that interpreted structures are not tightly constrained and the style of mineralisation e.g. veins etc is not clearly defined by RC drilling. RC drilling cannot provide structural orientation data and by its nature destroys the rock mass making textural and structural relationships difficult if not impossible to determine visually.
-
These limitations of RC drilling and the strong structural control have resulted in the resource being conservatively classified as an Inferred Resource.
Further information on the criteria used for classification is set out on page 12 of this announcement.
Artemis Drilling
Standards, duplicates and blanks were used for QA/QC checks by Artemis. Standards and blanks were inserted into the sample stream as every 20[th] sample and riffle split duplicate samples were collected at every 20[th] sample.
A total of 1,169 samples were duplicated in the field and 1,270 blanks and standard reference samples were inserted by Artemis into the drill sample batches.
Gold assays show a broader scatter within the duplicate samples than the Copper and Cobalt whose majority of samples fall within a +/-10% range, a summary of the duplicate results is shown in Table 3 . The Bias ratio = duplicate/original assay.
Table 3: Statistics for Artemis Drilling Duplicate pairs.
| Original | Original | Original | Duplicate | Duplicate | Duplicate | |
|---|---|---|---|---|---|---|
| **Au ppm ** | **Co ppm ** | **Cu ppm ** | **Au ppm ** | **Co ppm ** | Cu ppm | |
| Average | 0.35 | 258 | 1,797 | 0.31 | 252 | 1,805 |
| Correlation | 0.945 | 0.957 | 0.941 | |||
| Bias Ratio | 0.88 | 0.98 | 1.00 |
Of the standard reference samples only the first 18 (1.4%) showed results consistently below the preferred value, overall the assays of the standard reference materials fall within the normal range of variations for the elements at the grades tested.
Bulk Density
A total of 118,402 density measurements were collected from the Artemis drill holes using a downhole gamma/calliper/density/resistivity logger by Downhole Services Group. Of these measurements 26,237 were within the resource wireframes. The average density of the weathered mineralised measurements was 2.5 while the fresh mineralised samples averaged 2.9. To model the densities the down-hole densities were treated as assays and interpolated into the model using the same search parameters as the assays.

Downhole surveys
The first phase drill holes (ARV001 to ARC034) were surveyed using a north seeking magnetic camera, subsequently all holes were surveyed at 30m intervals using gyroscopic equipment to overcome the effects of any magnetic minerals that are probable in the mafic/ultramafic country rocks.
All accessible holes of the first phase of drilling were also re-surveyed using the gyroscopic equipment. When holes seemed to show excessive deviation from the gyroscopic survey, they were re-surveyed by a third party in association with the downhole density logging. All suspect deviations were confirmed to be valid.
ESTIMATION METHODOLOGY
The drilling database received by AM&A for this resource estimate was supplied by the Company as Excel spread sheets including each of drill hole collar coordinates, down-hole surveys, down hole lithology logs, sample recovery data and assays.
The data as received was entered into MineMap© software and checks were made to ensure that the hole IDs were correct and sample intervals did not overlap or were negative. No errors were found in the data.
The Carlow Castle project area was divided into four domains as shown in Figure 3:
-
North - essentially the Quod Est zone and other minor mineralization the east;
-
West - the Carlow South zone against the western terminating structure;
-
Central - the Carlow South zone where it strikes south of east and dips to the north; and
-
East - the Carlow South zone where it strikes east-west and dips to the south.

Figure 3: Carlow Castle Model Domains.
The resource model wireframes were developed on the basis of the gold, copper and cobalt contents being used to define the mineralised zones. The mineralisation was digitised using MineMap© software on cross sections, snapping to the drill intercepts using a generic metal factor algorithm calculated using London Metal Exchange (“LME”) prices at 31 December 2018 by (Au ppm * $36.97 ($USD1282.10/oz) * 90% metallurgical recovery + Cu% * $44.73 * 75% metallurgical recovery+ Co% * $408.75 ($54500/tonne) * 75% metallurgical recovery) >30.

MINERALISED ENVELOPE BOUNDARY DEFINITION
The metal unit threshold value of >30 was chosen solely to define the mineralised envelope boundary because the copper, cobalt and gold are strongly associated with each other in the lodes and are all potentially metallurgically recoverable. Sample intervals within the interpreted lode below the designated 30 metal units’ content were included within the lode wireframe where this internal dilution did not drop the total intersection below 30 and where it provided improved continuity with other adjacent drill intersections of the lode, Figure 4 .

Figure 4: Cross section at 507,520 mE +/- 5m looking west showing digitised mineralised zones with holes colour coded by Metal Factor.
The mineralised zones on each cross-section were then linked by wireframes to produce “solids”. The base of oxidation was triangulated from the drill hole geology logs. These wireframes were extended along strike beyond the last mineralised drill intercept by a maximum of 10 m, quarter of the nominal drill line spacing, and down-dip by half way to a limiting drill hole or by a maximum of 40 m.

Au, Co and Cu were separately estimated using both uncut and cut (top cut) grades. Separate top cuts were calculated for each domain at the Mean+2 Standard Deviations, Table 4.
Since the drill samples were assayed at a combination of 1 m samples and for some of the diamond drilling at shorter intervals, the drill assays were composited to standard 1m intervals to avoid volume variance effects.

RESOURCE ESTIMATE
Considering the spacing of the drill intersections, quality of the drilling and sampling and the degree of understanding of the geological controls on the mineralisation, AM&A have classified the reported resources at Carlow Castle as Inferred according to the JORC Code (2012).
Newly obtained data informing this resource estimate includes 12 diamond drillholes, (1504.6m) and 108 reverse circulation drillholes (15,882m). This drilling occurred both within the existing resource and mainly outside the existing resource in previously undrilled areas along strike. The resource has been totally remodelled reflecting the impact of this new data.
In addition, there has been an increase in the amount of metallurgical data available since the previous resource estimate, regarding recoveries and potential products (refer to ASX announcement 11 February 2019, Carlow Castle Au-Cu-Co metallurgical update (“Metallurgical Update”)).[2]
With regards to the 2019 resource estimate:
-
the resource is drilled on a relatively close spaced pattern, nominally 40m line spacing and 20m collar spacing yielding a nominal 25m down dip spacing.
-
Interpretations for wireframing were extended; along strike from the last mineralised intercept by a maximum of 10m, one quarter of the nominal drill section spacing, and down dip from the last mineralised intercept by a maximum of 40m averaging 27m
-
the majority of the drilling is RC drilling.
-
the mineralisation is interpreted as being predominantly structurally controlled and occurs as veins, stockworks and breccias.
-
The limited amount of diamond drilling has meant the structural interpretation relies heavily on RC drilling supported by limited mapping and interpretation of geophysical data. This means that interpreted structures are not tightly constrained and the style of mineralisation e.g. veins etc is not clearly defined by RC drilling. RC drilling cannot provide structural orientation data and by its nature destroys the rock mass making textural and structural relationships difficult if not impossible to determine visually.
-
These limitations of RC drilling and the strong structural control have resulted in the resource being conservatively classified as an Inferred Resource.
AM&A estimated the total Inferred resource at Carlow Castle South and Quod Est to be approximately 7.7 million tonnes at 1.06 g/t Au, 0.08% Co, 0.51% Cu based on the lode wireframes (at a 0.3 g/t Au lower grade cut-off) but using the upper cut grades, Table .
The 0.3 g/t Au cut-off grade, at a current gold price of $A59.10/gram has a value of $A17.73, without considering the additional copper and cobalt value. At this early stage of project evaluation, various processing options are being investigated and considered. The cut-off grade selected is a marginal cut-off which approximates anticipated processing costs and takes into consideration the newly obtained metallurgical data published in the Metallurgical Update.

The cut-off threshold permits inclusion of mineralisation which may satisfy a marginal cut-off in an open pit mining scenario.

METALLURGICAL TESTWORK
As set out in the Metallurgical Update, Artemis has completed preliminary metallurgical testwork on the Carlow Castle Au-Cu-Co Project at ALS Metallurgy in Western Australia. The programme focussed on metallurgical amenability on selected samples from the Carlow Castle deposit employing conventional gravity gold, cyanide leach and flotation processes. Outcomes specific to the metallurgical response and recovery for three target commodities (gold, copper and cobalt) are proposed to be used for further project development evaluations.
The results to date confirm amenability for gold, copper and cobalt processing with excellent recoveries. Analysis of the metallurgical results indicate:
Gold
-
Significant gravity recoverable gold component - ranging up to 48% and suitable for on-site processing into gold doré;
-
The balance of the non-gravity gold is expected to be recovered into flotation concentrates - as a byproduct credit or recovered by a cyanide leach process;
-
Cyanide leach testwork confirms amenability to conventional low-cost gold recovery processes - with exceptional final tailings grades 0.03 to 0.10 g/t.
Copper
- Fast floating copper minerals produce high-grade, premium copper concentrate – of approximately 30% Cu;

-
Key deleterious elements including arsenic are easily managed with a light polishing regrind or blend control - COM-01 is considered a high-grade sample and therefore comes with elevated arsenic linked to the cobalt mineral; arsenic levels are expected to return in line with COM-02 (0.3% As) and as such be well below smelter limits circa 0.5% As;
-
Recoveries in line with mineralogy realising 77–85% copper recovery - unrecovered copper minerals are predominantly represented by non-floating silicates or secondary copper minerals.
Cobalt
-
Cobalt recoveries ranging 73-79% - are considered exceptional for the preliminary nature of the current metallurgical testwork programme;
-
Cobalt concentrate grades ranging 2.3–5.3% Co are saleable – with circa 3% Co concentrates being typical smelter feed and >5% Co being considered high grade – it should be noted that concentrate grades as high as 19% Co were achieved in several tests conducted. Mineralogy conducted on cobalt concentrates from COM-01 and COM-02 indicate well liberated minerals (cobaltite and gangue) and are amenable to significant further upgrade. Testwork continues to improve cobalt concentrate grades and ultimately aims to maintain optimal recovery and reduce shipping / smelter treatment charges;
-
Cobaltite (CoAsS) is the dominant cobalt bearing mineral - and is therefore intrinsically linked to arsenic. Targeting lower specification Co concentrates will minimise processing capital and if high specification Co concentrates are targeted a higher capital, hydrometallurgical flowsheet will be required. As such and with a view to optimising returns, a trade-off study of capital and operating expense versus revenue from differing grade product streams will be evaluated prior to final flowsheet selection.
Other Modifying Factors
Aside from as set out above, the Company has not yet considered other material modifying factors. It has been assumed that the mineral resources at Carlow Castle and Quod Est will be mined using open cut mining methods as the bulk of the resource is above 150m in vertical depth below natural surface and more suited to this type of extraction.
Material changes since last estimate
The Company notes that it has materially updated its Mineral Resource since the last estimate provided to the market on 31 January 2018. The upgrade is based on the information and assumptions set out in this announcement and the results are summarised in Table 1 of this announcement and supersedes the resource estimate made on 31 January 2018.

| 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. • 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. • All intervals reported are length weighted. • No upper or lower cut off grades have been used for reporting Exploration Results in this report. • No metal equivalent calculations are used for reporting Exploration Results in this report. |
||
| 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 (eg ‘down hole length, true width not known’). • True widths of mineralisation have not been calculated for this report, and as such all intersections reported are down-hole thicknesses. • Due to the moderately to steeply dipping nature of the mineralised zones, it is expected that true thicknesses will be less than the reported down-hole thicknesses. • The resource modelling was carried out in 3D and all apparent widths accounted for in the estimation method. |
||
| 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. • Appropriate maps and sections are available in the body of this announcement. |

Section 3 Estimation and Reporting of Mineral Resources
(Criteria listed in section 1, and where relevant in section 2, also apply to this section.)
| Criteria JORC Code explanation Commentary |
||
|---|---|---|
| Database integrity • Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. • Data validation procedures used. • Data used as received was checked for Hole ID and sample interval errors by MineMap © software. Some RC sample assays in database were checked against laboratory spread sheets and no errors were found. |
||
| Site visits • Comment on any site visits undertaken by the Competent Person and the outcome of those visits. • If no site visits have been undertaken indicate why this is the case. • A site visit including discussions with company personnel was conducted by Al Maynard of AM&A on 9th January 2018 and Phil Jones visited the project on Friday, 20 July 2018 confirming the drill hole locations, discussed the regional and local geology and drilling and sampling procedures used by Artemis with Allan Younger. Phil Jones also visited the nearby Radio Hill processing plant where any ore mined at Carlow Castle may be processed. |
||
| Geological interpretation • Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral deposit. • Nature of the data used and of any assumptions made. • The effect, if any, of alternative interpretations on Mineral Resource estimation. • The use of geology in guiding and controlling Mineral Resource estimation. • The factors affecting continuity both of grade and geology. • The mineralisation is controlled by shears dipping steeply to the north. The mineralisation cannot be mapped at the surface due to soil cover however can be confidently interpreted from drilling data. Some supergene effects may have remobilised and possibly enriched some of the mineralisation in the upper oxidised zone. |
||
| Dimensions • The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource. • The modelled mineralisation at Quod Est strikes approximately 270 m north-south. The mineralisation is not properly closed off along strike or down dip. • The modelled mineralisation at Carlow Caste South strikes approximately 1,200 m east-west and with multiple lodes spanning a zone up to 35 m north-south. The mineralisation is not properly closed off down dip. |
||
| Estimation and modelling techniques • The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by- products. • Estimation of deleterious elements or other non- grade variables of economic significance(eg sulphur • The mineralisation was digitised using MineMap© software on cross sections, snapping to the drill intercepts using a generic metal factor calculated using London Metal Exchange (“LME”) prices at 31 December 2018 by (Au ppm * $36.97 ($USD1282.10/oz) * 90% metallurgical recovery + Co% * $408.75 ($54500/tonne) * 75% metallurgical recovery + Cu% * $44.73 * 75% metallurgical recovery) >30. This metal unit threshold value was chosen to define the mineralised envelope because the copper, cobalt and gold are intimately associated with each other in the veins and are all potentially metallurgically recoverable. Sample intervals within the interpreted lode below the designated 30 metal units’ content |

| Environmental factors or assumptions • Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation. While at this stage the determination of potential environmental impacts, particularly for a greenfields project, may not always be well advanced, the status of early consideration of these potential environmental impacts should be reported. Where these aspects have not been considered this should be reported with an explanation of the environmental assumptions made. • No environmental factors were considered however the tenement has sufficient suitable area to accommodate a modest mining and processing operation including provision for waste disposal. • Recent studies have not identified areas which are especially environmentally sensitive in the vicinity of the deposit. Future studies may be required by various authorities to remain in compliance with government regulation as the project progresses. |
||
| Bulk density • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluationprocess of the different materials. • A total of 118,402 density measurements were collected from the Artemis drill holes using a downhole gamma/calliper/density/resistivity logger by Wireline Services Group. Of these measurements 26,237 were within the resource wireframes. The down-hole densities were modelled using the same parameters used to estimate the grades. |
||
| Classification • The basis for the classification of the Mineral Resources into varying confidence categories. • Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result appropriately reflects the Competent Person’s view of the deposit. • Considering the spacing of the drill intersections, quality of the drilling and sampling and the degree of understanding of the geological controls on the mineralisation, AM&A have classified the reported resources at Carlow Castle as Inferred according to the JORC Code (2012). • AM&A believes that this classification to be appropriate. |
||
| Audits or reviews • The results of any audits or reviews of Mineral Resource estimates. • No audits or reviews of the Mineral Resource Estimates have been made. |
||
| Discussion of relative accuracy/ confidence • Where appropriate a statement of the relative accuracy and confidence level in the Mineral Resource estimate using an approach or procedure deemed appropriate by the Competent Person. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could affect the relative accuracy and confidence of the estimate. • The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to • AM&A have classified the reported resources at Carlow Castle as Inferred according to the JORC Code (2012). • This resource classification appropriately considers the relative accuracy of the estimates. The Inferred resource estimate relies on drill hole sampling and other geological data of sufficient quality, amount and its distribution to imply but not verify an interpretation of the geological framework and continuity of mineralisation. • The quality of the data is considered to be reasonable for a resource estimate with adequate reportingof theQA/QC. |
