VANCOUVER, BRITISH COLUMBIA–(Marketwired – Aug. 27, 2015) –
- 10.6m interval of copper-rich massive sulphides intersected in CD15-14 – the first hole drilled to test the 175m-long Lense 7/8 IP Target
- This intersection again provides further confirmation that high-grade mineralisation coincides with strong IP anomalies at the Caribou Dome Project
- 4 other very similar untested IP anomalies will be drill tested for the first time during the current 4,000m exploration diamond drilling program
- The 5 priority targets being drill tested during the current program have a combined strike extent of >1,200m
- This demonstrates the considerable potential to discover additional high-grade mineralisation during the current drilling program
2. INITIAL DRILLING AT THE LENSE 7/8 TARGET
Coventry Resources Inc. (ASX:CYY); (“Coventry” or “the Company”) is pleased to announce that multiple intervals and significant thicknesses of massive sulphides have been intersected in the first hole it has drilled to commence evaluation of the Lense 7/8 Target at the highly prospective high-grade Caribou Dome Copper Project in Alaska, USA (the “Caribou Dome Project” or “the Project”).
The Lense 7/8 Target comprises a strong, 175m-long Induced Polarisation (“IP”) anomaly located between outcropping mineralisation at Lenses 7 and 8 (see Figures 1 and 2).
Only one shallow hole (DH36) had previously been drilled in the immediate vicinity of the Lense 7/8 Target. DH36 intersected 0.6m at 10.1% copper from 32.9m down-hole (approximately 20m below the surface).
2.1 Drill Hole CD15-14
Data from the Company’s recently completed IP survey delineated a strong, broad IP anomaly immediately below the mineralisation intercepted in DH36. To commence evaluation of this high-priority target, CD15-14 was drilled to test the IP anomaly approximately 70 metres beneath the surface (see Figure 1).
Initial visual inspection of diamond drill core from CD15-14 indicates six intervals of well-mineralised semi-massive to massive sulphides have been intersected. One of these intervals comprises 10.6 metres of copper(chalcopyrite)-rich massive sulphides (from 137.5m down-hole; see photos below and Figure 1). The thickness of the other observed intervals ranges from 0.3 to 2.1 metres.

Diamond core is currently being processed in advance of submitting samples for laboratory analysis. Assay results are expected to be available in 2-3 weeks’ time.
2.2 Follow-up Drilling – CD15-15
A second hole, CD15-15 is currently being drilled at the Lense 7/8 Target from the same drill pad used to drill CD15-14, with the drill rig inclined at 57° (as opposed to 45° for CD15-14). CD15-15 will test the area approximately 50 metres down-dip of the mineralisation intersected in CD15-14 i.e. approximately 120 metres below surface (see Figure 1).
3. ONGOING 4,000 METRE DIAMOND DRILLING PROGRAM
On 20 August 2015 Coventry announced it had commenced a 4,000 metre drilling program focused on first-pass exploration of five very-high-priority IP anomalies – the Lense 2, Lense 6 East, Lense 4 West, Caribou South and Lense 7/8 Targets (see Figure 2).
Where there is known high-grade copper mineralisation across the project, there are coincident strong IP anomalies. Accordingly, the five untested strong IP anomalies being targeted during the current drilling program, which are all located in prospective geological settings, are considered likely to be associated with thick and/or high-grade mineralisation.
Importantly, most of the mineralisation drilled previously in any detail extends over only approximately 250 metres of strike (~150 metres of strike at Lenses 5 and 6, and ~100 metres of strike at Lense 4). The combined strike extent of the five targets being tested in the current drilling program is greater than 1,200 metres; hence these targets provide considerable opportunity to significantly add to the Project’s resource base.
One diamond core rig continues to drill at the Project. A second drilling rig is currently in transit on its way to the Project to accelerate the 4,000m drilling program, and is expected to be operational late this week.
Assay results are pending for four other holes (CD15-10 to CD15-13). These are expected within the next week.

Note: Within the reported mineralized intervals in CD15-03 and CD15-04, in both holes, there were two separate intervals of 0% core recovery that totaled 1.2 metres per hole. Within the first reported mineralized interval in CD15-06, there was a 1.2m interval of 0% core recovery and in the second reported mineralized interval there was a 0.7m interval of 0% core recovery. These intervals have been assumed to be mineralized at the average grade of the overall mineralized interval.
CARIBOU DOME COPPER PROJECT – BACKGROUND
Mineralisation was first discovered at the Caribou Dome Copper Project in 1963. Between 1964 and 1970 nine lenses of sediment-hosted copper mineralisation were delineated over approximately 750 metres of strike. Some 95 diamond core holes were drilled during this period from surface and underground, primarily concentrated on just 250 metres of strike. Exceptional results were returned, including:
- 18.1m at 9.34% copper
- 18.4m at 6.25% copper
- 15.4m at 7.01% copper
- 13.1m at 7.20% copper
- 11.0m at 8.20% copper
- 10.4m at 7.94% copper
- 12.8m at 5.78% copper
Very limited exploration had been undertaken since 1970, until Coventry secured the rights to explore the Project in February 2015. Since then Coventry has compiled all historic technical information, prioritised targets arising, undertaken a ground geophysics (induced polarisation) survey, and commenced a diamond core drilling program. Coventry’s confirmatory drilling to date accords with previous work and its initial exploration results to further expand the Project have been very promising.

JORC CODE 2012 EDITION, TABLE 1 REPORT
JORC Code, 2012 Edition – Table 1
Section 1: Sampling Techniques and Data
(Criteria in this section applies 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 downhole 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
|– Core was sawn in half to provide a geologically representative sample for analysis by a professional laboratory
– Sample intervals were selected by a qualified geologist upon visual inspection of the core.
– Samples were submitted to ALS Laboratories in Fairbanks, Alaska.
– Sample were analysed using an aqua regia digestion and ICP-MS multi-element analysis.
– Samples containing +1% Cu were automatically re-analysed with an aqua regia digestion and an ore grade analysis using an ICP-AES finish to more accurately determine the high grade Cu assays.
|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.).||– A wireline core drilling rig was used to drill HQ core with a diameter of 63.5mm using a standard tube.
– Downhole surveys were completed using a Ranger Discoverer survey tool.
– Core is oriented by the drillers at the rig each run using the Fordia, Corient tool.
|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
|– Drillers record the drilled length and recovered length of core for each run on their run sheets. Geologists also measure and calculate recovery as a percentage drilled.
– HQ core was drilled to maximize recovery.
– Competent, experienced drillers were engaged.
|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
|– Core is geologically and geotechnically logged by qualified geologists. Where possible structural angles are measured for later interpretation.
– Core is qualitatively logged and all trays are photographed.
|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.
|– Core is cut in half, with half retained in the core box and the other half submitted for analysis. When duplicates are required this was noted on the sample dispatch. The half core sent for assay was split at the crushing stage by the laboratory and run as two separate samples. The geologists had, at the time of sample submission, assigned a sample number and provided a labelled sample bag for the duplicate split.
– The sample preparation technique is industry standard. HQ core is used and therefore provides a larger sample than more commonly used smaller diameter core.
– Duplicates, blanks and Certified Reference Materials (or standards) have been inserted approximately every 30 samples as an external quality control on the laboratory.
– Half HQ core is an appropriate sampling methodology for the mineralised material.
|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 have been submitted to ALS Laboratories in Fairbanks, Alaska, a globally recognized analytical laboratory.
– Duplicates, blanks and Certified Reference materials were inserted approximately every 30 samples as an external quality control on the laboratory.

|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
|– When undertaking due diligence on the Project during 2014, an Alaskan law firm confirmed that the Alaskan State Mining Claims (tenements) are in good standing.
– During October 2014 the annual renewal fees for all of the Claims were paid, well in advance of the 1 December 2014 renewal deadline. This ensures they are all in good standing until 1 September 2015.

– The operations are permitted by Alaska Department of Natural Resources.
|Exploration done by other parties||– Acknowledgment and appraisal of exploration by other parties.||– The site has been explored intermittently since discovery in 1963. There are 112 historic drill holes on the project, 2 exploration adits and numerous geophysical and geochemical surveys.|
|Geology||– Deposit type, geological setting and style of mineralisation||– The deposit is a sedimentary hosted copper deposit, where sulphides are interpreted to have precipitated in a basinal environment, and to have been and to have been deposited contemporaneously with the sediments.|
|Drillhole Information||– A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drillholes:
-easting and northing of the drillhole collar
– elevation or RL (Reduced Level elevation above sea level in metres) of the drillhole collar
– dip and azimuth of the hole
– downhole length and interception depth
– 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
|– A table of the holes completed is included in the body of the announcement.|
|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
|– Exploration results have been reported on a weighted average basis.
– No top cut has been applied and is not deemed necessary due to consistent high grades.
– The amount of internal subgrade included in significant intercepts was kept to a minimum and alternative significant intercepts were provided.
|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 drillhole angle is known, its nature should be reported.
– If it is not known and only the downhole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’).
|– Where possible drilling was conducted perpendicular to the interpreted dip and strike of the deposit. This was not always possible, due to (i) the deposit’s dip and strike being unknown and/or (ii) topographic constraints.
– This is addressed in the body of the announcement.
|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 drillhole collar locations and appropriate sectional views||– Diagrams, sections and tables showing the location of intercepts are included in the body of the announcement.
– The significant intercepts for all assay data received are included in the body of the announcement.
|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 significant results are 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.||– This announcement is reporting on both the assay results received to date and some geological and visual representations of the core for which assays are yet to be received.|

– 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 drill program is continuing and other assay results are still pending.
– Initially, future drilling will be focused on the lateral and depth extensions of the known and mapped mineralized lenses.
– A recent 3DIP survey has generated multiple new targets that have previously been outlined in plan and section. These will be systematically followed up in conjunction with drilling and further exploration.
