KEY POINTS:
-
A R everse Ci r culation ( R C) drill ri g has now complete d the exp a nded 47-hole drillin g pr o gram (9,6 4 2 metres) at the Bibra Gold Deposit;
-
As s ay results returned t o date for t he comple t ed holes are detailed in Tables 2 and 3.
-
This drilling has been focused on the “Main Lode” in th e northern area of th e optimise d op e n pit (Figure 2). T h ese initial results i n dicate th a t there is strong c o ntinuity o f mi n eralisatio n outside of the c u rrently reported In f erred Re s ource an d that th e mi n eralised s h ear zone r emains consistent at depth (Fi g ures 3a-b). The drilli n g remain s wi d e spaced o n a 50 metre by 50 m etre grid;
-
Th e Main Lo d e is made up of a broad zone of mineralisation (u p to 50 m e tres thick ) with two disti n ct internal intervals o f minerali s ation;
-
A s eries of n arrower, but poten t ially signi f icant, mi n eralised l o des have also bee n int e rsected in shallower, hanging w all positio n s;
-
Go l d mineralisation is typically hosted by a sh e ared, py r itic meta - sandston e int e rbedded w ith minor a mphibolit e that is re a dily identifiable in the RC chips; and

NEXT STEPS
With the R C drilling program n ow compl e te and assays recei v ed for 14 of the 47 holes, th e next step is to await the retu r n of all a n alytical d a ta from t h e laboratory. These results ar e scheduled to be rep o rted in batches over the next t hree wee k s. Results will be an n ounced a s they beco m e available.
This drilli n g information will t h en be us e d as the basis for a n update d resource estimatio n during Ju n e 2016
MANAGEMENT COMMENT
Capricorn’s Managin g Director, Mr Peter T hompson , said the l atest batc h of assay data fro m the recen t ly completed maide n drilling p rogram i n cluded so m e significant thick g old zone s down-dip o f the exis t ing Bibra r esource.

“We are very pleased both with the rapid completion of this phase of drilling ahead of schedule and on budget and with the excellent results received to date,” he said. “Ranger Drilling and our geological team are to be congratulated on completing this programme ahead of schedule and to a very high quality.
“Results received from the first 14 holes have confirmed the continuity of the mineralisation both in terms of thickness and grade in this area down-dip of the existing Bibra resource. Planning is well advanced for a Bibra resource update in June, following receipt of all assay results, and for other Scoping Study activities.
“At the same time, some important advances in our geological understanding of the controls on gold mineralisation at Karlawinda have been made, and we are developing some exciting new exploration targets outside of Bibra.”

|---|---|---|---|
| Classification | Tonnes (Mt) | Au g/t | Contained Au (Oz) |
| Measured | -- | -- | -- |

| Inferred | 18 | 1.1 | 650,800 |
| 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 cutoff 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, whether core is oriented and if so, by what method, etc.). |
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 using a 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 |
• Method of recording and assessing core and chip sample recoveries and results assessed. |

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 thepresence ofgarnets in |

| 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. |

Section 2 Reporting of Exploration Results
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Mineral tenement and land tenure status |
• 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 security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
•The Bibra deposit is located in EPM52/1711 held by INDEPENDENCE KARLAWINDA PTY LTD. Capricorn Metals is currently in a purchase agreement with Independence Group Ltd, where acquisition will be finalised in 2016. Please see Capricorn Metals ASX at http://capmetals.com.au/ for further details •The Bibra mineralisation is within the granted E52/1711 exploration tenement in the Pilbara region of Western Australia. E52/1711 was acquired from BHPB in 2008. BHPB retain a 2% NSR and a claw-back provision whereby BHPB can elect to acquire a 70% equity in the project only if JORC compliant reported resources of 5,000,000 ounces of gold and/or 120,000 tonnes of contained nickel have been delineated. The Nyiyaparli group are Native Title claimants covering an area including E52/1711. There is no known heritage or environmental impediments over the lease. A mining lease sufficient in size to cover the Bibra resource area and potential associated infrastructure for a future mining operation has been applied for, and IGO is currently in negotiation with the Nyiyaparli group over this application. •No other known impediments exist to |

| operate in the area. | ||
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
•Prior to Capricorn Metals, the tenement was held by the Independence group who undertook exploration between 2008 & 2014. Prior to Independence group, WMC explored the area from 2004 to 2008 |
| Geology | • Deposit type, geological setting and style of mineralisation. |
•Bibra is part of a large-scale Archaean aged gold mineralized system. The resource is hosted within a package of deformed meta-sediments which has developed on at least two parallel, shallow dipping structures; supergene oxide mineralization has developed over the structures close to surface. The primary mineralization is strata-bound with lineations identified as controlling higher-grade shoots. The deposit is oxidized sSto average depths of 50-70m. |
| 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: o easting and northing of the drill holecollar o elevation or RL (Reduced Level –elevation above sea level in metres) of the drill hole collar o dip and azimuth of the holeo down hole length and interceptiondepth 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. |
•Refer to Tables 1 & 2 in Appendix 1 and the text for drill hole information. |
| 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. • 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. |
•In the ore zone four separate fire assays were completed for each 1m sample to reduce the nugget effect. The four assays were then averaged to calculate the final assay grade. |
| 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 |
•At Bibra, the geometry of the mineralisation has already been defined from previous drilling programs. The intersection angle between drill angle and the perpendicular angle to the ore zone is less than 10 degrees. |

| lengths are reported, there should be a clear statement to this effect (e.g. ‘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. |
•The diagrams in the report provide sufficient information to understand the context of the drilling results. |
| 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. |
•The accompanying document is considered to be a balanced report with a suitable cautionary note. |
| 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. |
• Systematic metallurgical testwork programs over 2012/13 on master and variability composites from diamond core identifies mineralisation as free milling and amenable to cyanidation |
| 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. |
•The drillhole reported are part of a larger drill program at Bibra. To date 11 holes have been completed out of 40 holes planned. •Further work will involve drilling (RC and Diamond) to upgrade and expand the Bibra resource. In addition work will involve large scale (regional) step-out drilling for determination of additional mineralisation. |
