KARLAWINDA SET FOR RESOURCE UPGRADE FOLLOWING MORE STRONG GOLD RESULTS
Updated resource for Bibra deposit due by the end of June as final assays confirm significant extensions
ASX ANNOUNCMENT 10 June 2016
Australian Securities Exchange Code: CMM
HIGHLIGHTS
-
Final results (5 holes) from the 47-hole resource expansion drilling program at Bibra have now been returned.
-
The results continue to confirm significant extensions of quality gold mineralisation well outside the current Inferred Resource boundary (18Mt at 1.1g/t for 650,800oz – Table 1).
-
Significant results from the final batch of assays include (see Tables 2 and 3):
ABN: 84 121 700 105
-
KBRC 328: 13 metres @ 1.63g/t Au from 171m
-
KBRC 326: 22 metres @ 1.10g/t Au from 236m

Mr Peter Thompson Managing Director
Mr Peter Langworthy Technical Director
Mr Heath Hellewell Non-Executive Director
Issued Capital:
Shares 487M Options 18.7M Share Price A$0.15 Market Cap. A$73M
-
KBRC 330: 22 metres @ 1.36g/t Au from 178m
-
Results from the last five holes confirm that strong gold mineralisation extends for at least 200m down-plunge beyond the limits of previous drilling.
-
Mineralisation has been intersected in all 47 holes drilled by Capricorn as part of this maiden drill program, laying the foundations for a significant expansion of the Bibra resource.
-
Based on these new results and those previously announced, it is expected that the resource will extend well beyond the current optimised open pit boundary, resulting in a significant upgrade to the resource.
-
Resource modelling activities are well advanced with results expected to be available for reporting by June 30.
-
With strong upcoming news-flow from Karlawinda including the imminent resource upgrade, Scoping Study activities and ongoing exploration and development studies, Capricorn is well placed to take advantage of the strong market environment for Australian gold projects.

10th June 2016 : Capricorn Metals Ltd (ASX: CMM) is pleased to advise that final results have now been returned from the recently completed 47-hole resource expansion drilling program at the Bibra Gold Deposit, part of its 100%-owned Karlawinda Gold Project in WA’s Pilbara (Figure 1).
The last five drill holes of the program all intersected significant mineralisation, confirming that the mineralisation extends for at least 200m beyond the limits of previous drilling. These latest assays, combined with the previously announced results, confirm significant extensions to the Bibra deposit, putting Capricorn firmly on track to deliver a significant upgrade to the JORC resource estimate for the Bibra deposit in June .
The Karlawinda Gold Project is located in the Pilbara region, 65km south-east of Newman in WA, within the Archaean aged Sylvania Dome Inlier (Figure 1). Karlawinda is an advanced gold project which includes the Bibra deposit and numerous outstanding exploration targets including the Francopan prospect.

KEY POINTS:
-
A series of drill-holes (KBRC 324 to 330) were drilled to test for significant extensions of the mineralisation outside of the current resource in the down-dip position. The results demonstrate that strong gold mineralisation extends for at least a further 200m down-dip and has the potential to expand the resource well beyond the current resource boundary (Figure 2). The results from this drilling include:
-
KBRC 326: 22 metres @ 1.10g/t Au
-
KBRC 328: 13 metres @ 1.63g/t Au
-
KBRC 330: 22 metres @ 1.36g/t Au
-
KBRC 324:* 26 metres @ 1.48g/t Au and 6 metres @ 2.49g/t Au
-
KBRC 325:* 25 metres @ 1.05g/t Au and 14 metres @ 1.12g/t Au
-
-
(* Previously announced results – see Tables 2 and 3 for details)

-
As with the previously reported results, the new results continue to match or exceed the anticipated widths and grades predicted by previously completed wide-spaced drilling. The new results are expected to add significantly to the existing Inferred Resource (Tables 2 and 3); and
-
Deeper mineralisation increasingly extends beyond the current base of the 2012 optimised pit shell and is now expected to extend the resource into these areas (Figure 4).

MANAGEMENT COMMENT
Capricorn’s Managing Director, Mr Peter Thompson, said the receipt of the final assay results from the recent 47-hole drill program at Karlawinda marked another significant step forward for the project.
“ It is a reflection of the quality and scale of the Bibra deposit that we have been able to report significant mineralisation in every single hole drilled as part of this maiden drill program,” he said.

“ The assay results reported today include some important intersections down-dip of the previously identified mineralisation which are expected to impact on the imminent Resource Upgrade and Scoping Study.
“We are very pleased with the progress we have achieved at Karlawinda in a relatively short space of time, and we are looking forward to what will be a very busy second half of the year as we advance this high-quality mid-tier gold asset towards potential development.”

| GRAND TOTAL | 18 | 1.1 | 650,800 |
Notes:
-
The Mineral Resource estimate was estimated within a conceptual A$1,600/oz Au pit shell completed in 2012 and for the area of drill coverage at 100m x 50m spacing or less. Contained gold (oz) figures have been rounded to the nearest one hundred ounces.
-
The Mineral Resource has been unchanged since 2013.
-
Mostly RC drilling with 1m cone split samples analysed by 50g fire assay.
-
Mineralisation was wireframed at a cut-off grade of 0.3g/t Au and Mineral Resources were reported above a cut-off grade of 0.5g/t Au.
-
Block modeling used ordinary kriging grade interpolation methods for composites that were top-cut to 10g/t Au in the supergene zone and 16g/t Au for the remaining mineralization. Top cuts are not severe, trimming no greater than 0.5% of the samples.
-
There are no Ore Reserves for Karlawinda.

Section 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections.)
| 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. 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 (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. |
2kg - 3kg samples were split from dry 1m bulk samples. The sample was initially collected from the cyclone in an inline collection box with independent upper and lower shutters. Once the metre was completed, the drill bit was lifted off the bottom of the hole, to create a gap between sample, when the gap of air came into the collection box the top shutter was closed off. Once the top shutter was closed, the bottom shutter was opened and the sample was dropped under gravity thorough a Metzke cone splitter. Once drilling reached fresh rock a fine spray of water was used to suppress dust and limit the loss of fines thorough the cyclone chimney. A second 2kg-3kg sample was collected at the same time the original sample. This sample has been stored on site. These duplicate samples have been retained for follow up analysis and testwork. The bulk sample of the main ore zone was discharged from the cyclone directly into green bags. The bulk sample from the waste and hanging wall zones was collected in wheelbarrows and dumped into neat piles on the ground. During the sample collection process, the cone split, original and duplicate calico samples and the reject green bag samples were weighed to test for bias’s and sample recoveries. The majority of the check work was undertaken through the main ore zones, however approximately 10% of the holes drilled had the whole hole weighed. Field duplicates were collected at a ratio of 1:20 through the mineralised zones and collected at the same time as the original sample through the B chute of the cone splitter. OREAS certified reference material (CRM) was inserted at a ratio of 1:20 through the mineralised zone. The grade ranges of the CRM’s were selected based on grade populations and economic grade ranges. |
| 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, |
All Drilling has been completed by reverse circulation using a DRA600 RC rig with 1350cfm@500psi compressor with a 1800cfm x 800psi booster and 900cfm, 350psi auxiliary. The hole was drilled usinga nominal 135mm diameter face |

sampling bit, and to limit the hole deviation 4metre thick wall rod and top and bottom stabilisers were used. |
|
| Drill sample recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. 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. |
During the sample collection process, the cone split, original and duplicate calico samples and the reject green bag samples were weighed to test for bias’s and sample recoveries. The majority of the check work was undertaken through the main ore zones, however approximately 10% of the holes drilled had the whole hole weighed. Once drilling reached fresh rock a fine spray of water was used to suppress dust and limit the loss of fines thorough the cyclone chimney. At the end of each metre the bit was lifted off the bottom to separate each metre drilled. The majority of samples were of good quality with ground water having minimal effect on sample quality or recovery. From the collection of recovery data, no identifiable bias exists. |
| 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. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. The total length and percentage of the relevant intersections logged. |
Reverse circulation chips were washed and stored in chip trays in 1m intervals for the entire length of each hole. Chips were visually inspected and logged to record lithology, weathering, alteration, mineralisation, veining and structure. |
| Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core taken. 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 sample preparation 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. |
Samples were split from dry, 1m bulk sample via a cone splitter directly from the cyclone. The quality control procedure adopted through the process includes: Weighing of both Calico samples and reject sample to determine sample recovery compared to theoretical sample recovery and to check sample bias through the splitter. Field duplicates were collected at a ratio of 1:20 through the mineralised zones and collected at the same time as the original sample through the B chute of the cone splitter. OREAS certified reference material (CRM) was inserted at a ratio of 1:20 through the mineralised zone. The grade ranges of the CRM’s was selected based on grade populations and economic grade ranges The duplicate and CRM’s were submitted |

| to the lab using unique sample ID’s. A 2kg – 3kg sample were submitted to Intertek laboratory in Maddington in WA. Samples were oven dried at 105°C then jaw crushed to -10mm followed by a Boyd crush to a nominal -2mm. Samples were rotary split to 2.5kg. Samples were then pulverised in LM5 mills to 85% passing 75μm under sample preparation code EX03_05 which consists of a 5 minute extended preparation for RC/Soil/RAB. The extended time for the pulverisation is to improve the pulverisation of samples due to the presence of garnets in the samples All the samples were analysed for Au using the FA50/AAS technique which is a 50g lead collection fire assay |

| 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. 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. 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. |
Samples were submitted to the Intertek laboratory in Perth. In the waste zones, analysis has been completed by a single fire assay. In the main mineralised zone four fire assays from the sample pulp were completed and then averaged to determine, the assay grade of the sample to reduce the impact of the nugget effect in each ore zone sample The samples were determined for gold, pt, pd and additional elements/base metals, using ICP optical emission spectrometry and ICP mass spectrometry. Field duplicates were collected at a ratio of 1:20 through the mineralised zones and collected at the same time as the original sample through the B chute of the cone splitter. OREAS certified reference material (CRM) was inserted at a ratio of 1:20 through the mineralised zone. The grade ranges of the CRM’s were selected based on grade populations and economic grade ranges. |
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. |
Logging and sampling were recorded directly into a Micromine field marshal template, which utilises lookup tables and in file validation on a Toughbook by the geologist on the rig. Assay results when received were plotted on section and were verified against neighbouring holes. In the current program no twin holes have been completed. |

a Garmin hand held GPS. The coordinates were plotted and marked in GDA94 / MGA zone 51. Downhole surveys were collected by driller operated in-rod gyro at the end of each hole. Measurements were taken every 10 metres |
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. 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. Whether sample compositing has been _applied. _ |
Drilling is being completed on a 50x50m grid. Drill spacing is sufficient for current resource classification Samples collected and analysed for each metre down the hole. Whole hole is analysed. |
| 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. 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. |
Drill lines are oriented across strike on a local grid. Bibra orebody dips at 30 degrees to the North West. Hole in the current programs are being drilled at inclination of 90 degrees and intersect the ore body at an angle less than 10 degrees from perpendicular. |
