- Update on Exploration Program at the Perrinvale high grade VHMS Project
Cobre Limited (ASX: CBE , Cobre or Company ) is pleased to provide an update on its latest drilling program at the Perrinvale Volcanic-Hosted Massive Sulphide ( VHMS ) Project located in Western Australia ( refer Figure 4 ).
As announced to ASX on 10 June 2020, the Company was undertaking its third Diamond Core ( DC ) and Reverse Circulation ( RC ) drilling program at the Perrinvale Project with the twin aims of extending current VHMS mineralisation and drill testing new VHMS targets.
Both the RC and DD programs were recently completed, with RC drilling of 2,883m (including 120m of pre-collars for core holes) and the DC drilling of 2,086 metres ( refer Figure ).
==> picture [451 x 91] intentionally omitted <==
Assays from this third drill program have been received for all but the last three DC holes while the results received to date are encouraging. The latest drill results have:
-
1) confirmed the high VHMS grades at the Schwabe Prospect;
-
2) identified further mineralisation along the Zinco Lago - Lago Rame gossan trend; and
-
3) delivered positive results at the Costa del Islas, Piega del West and Ponchiera Copper prospects.
Drilling at the Schwabe Prospect
Three objectives were achieved following the most recent drilling at Schwabe including the:
-
1) generation of mineralised core samples for sighter metallurgical testing;
-
2) expanding upon previously drilled massive sulphide mineralisation; and
-
3) step out drilling to test for mineralisation at depth and along strike.
The drill hole location details and mineralised intercepts for all holes are included in Tables 1 and 2 of this announcement, with relative collar positions shown in Figures 2, 5 and 6 .
The first DC drill hole at Schwabe as part of this campaign, 20PVDD007, intersected 7m of sulphide mineralisation as two sulphide zones separated by 3 metres of internal basalt, and generated the following assay intervals: (as previously reported to ASX on 20 July 2020).
Sulphide zone: 3.5m@ 3.4% Cu, 0.8% Zn, 0.10% Co, 368 ppm Pb, 1.1 g/t Au, 16.5 g/t Ag from 48m Internal Basalt: 3.0m@ 0.03% Cu, 0.02% Zn, 0.00% Co, 7 ppm Pb, 0.01 g/t Au, 0.1 g/t Ag from 51m
Sulphide zone: 3.5m@ 2.0% Cu, 1.4% Zn, 0.07% Co, 344 ppm Pb, 0.3 g/t Au, 7.4 g/t Ag from 54m
Nearby DC drill hole 20PVDD014 encountered a semi massive to massive mineralised horizon, as can be seen in Figure 1 below, generating the following assay interval:
Sulphide zone: 5.4m@ 2.8% Cu, 1.3% Zn, 0.05% Co, 131 ppm Pb, 1.1 g/t Au, 12.1 g/t Ag from 67m
-
(including: 1.7m@ 6.2% Cu, 3.6% Zn, 0.10% Co, 304 ppm Pb, 2.5 g/t Au, 27.6 g/t Ag from 70m )
-
Three RC holes at Schwabe also returned shallow high grade VHMS assays as follows:
- 20PVRC021:
-
Sulphide zone: 10m@ 0.9% Cu, 0.4 % Zn, 0.02% Co, 205 ppm Pb, 0.2g/t Au, 2.3 g/t Ag from 23m (including: 4m@ 2.1% Cu, 0.6% Zn, 0.04% Co, 297 ppm Pb, 0.4 g/t Au, 5.2 g/t Ag from 23m )
- 20PVRC022:
Sulphide zone: 7m@ 2.0% Cu, 0.8% Zn, 0.04% Co, 80 ppm Pb, 0.4 g/t Au, 4.9 g/t Ag from 27m (including: 1m@ 7.8% Cu, 4.2% Zn, 0.04% Co, 433 ppm Pb, 1.5 g/t Au, 23.1 g/t Ag from 28m ) 20PVRC023:
- Sulphide zone: 12m@ 2.9% Cu, 1.0% Zn, 0.05% Co, 192 ppm Pb, 0.7 g/t Au, 10.2 g/t Ag from 45m (including: 4m@ 8.3% Cu, 2.9% Zn, 0.12% Co, 555 ppm Pb, 2.0 g/t Au, 29.8 g/t Ag from 45m )

Step out drilling at Schwabe has demonstrated that VHMS mineralisation extends along strike for 500m, which includes the previous drill area. The variable copper and zinc mineralisation is associated with narrow interflow sediments between the mafic pile. Figure 2 shows the holes and significant intercepts to date.
A single deep DC hole (20PVDD015) intersected some vein halo and disseminated mineralisation 200 metres down dip from the high grade massive sulphides drilled near surface, as shown on Figure 3 . Assays are yet to be received for this deep hole.

Drilling at Zinco Lago, Zinco Rame and Lago Rame Prospects
Geologically, the Zinco Lago, Zinco Rame and Lago Rame prospects are located along the same stratigraphic horizon on the western side of a broad syncline. The Schwabe prospect is located ~2km away on the eastern side of this syncline in the same stratigraphic position.
In total, 6 DC holes and 2 RC holes were drilled at Zinco Lago, Zinco Rame and Lago Rame as part of this drill campaign ( refer Figure 5 ). Assays have been received for 4 of the DC holes and the 2 RC holes to date as reported herein.
Visual observations from drill core and RC chips confirms the continuity of the mineralised horizon along trend at all three prospects. The deeper holes drilled to the east at Zinco Rame and Lago Rame have intersected a potential sub-parallel zone of mineralised sediments. The combination of exploration drilling, surface mapping and modelled conductors suggests an increase from ~2.5km to ~3.8km of the prospective stratigraphy in this location. Assays continue to show broad lower grade mineralisation associated with the interflow sediments in the areas drilled, with hole details and significant intercepts included in Tables 1 and 2 below.
The focus is now to identifying positions along the mineralised sediment horizons where higher concentrations of base metal sulphides might be expected. To this end, a gravity survey has been completed across the Zinco Lago, Zinco Rame and Lago Rame prospects, along with detailed field mapping. The final holes drilled at Zinco Lago (awaiting assays) were guided by early gravity survey results. All new data will be compiled along with results of the current Downhole Electromagnetic ( DHEM ) Surveys to plan further drilling at these prospects.
Mineralisation Intersected at other Drill Targets within the Perrinvale Project
Assays have confirmed intersection of mineralisation with the maiden drill programme at three of the four new prospects. The Company has completed RC drilling of the fold nose at Ponchiera Copper, Ponchiera North, Costa del Islas, and Piega del West prospects within the Perrinvale Project ( refer Figure 4 and 6 ). Only Ponchiera North failed to deliver some level of mineralisation in the RC assays.
The single hole at Costa del Islas, 20PVRC007, has confirmed geology similar to that intersected in the Zinco Lago, Zinco Rame and Lago Rame prospect areas, with three sulphide intersections down hole returning elevated base metals associated with a package of basalts, mudstones and carbonaceous shales (18-20m, 91-94m and 126-130m). The best intercept was:
Sulphide zone: 3m@ 0.04% Cu, 0.08% Zn, 86 ppm Co, 32 ppm Pb, 0.01 g/t Au, 0.7 g/t Ag from 91m
(including: 1m@ 0.06% Cu, 0.14% Zn, 117 ppm Co, 40 ppm Pb, 0.003 g/t Au, 0.8 g/t Ag from 92m )
The area was first identified after the Company completed an Airborne Electromagnetic ( AEM ) survey prior to listing on the ASX. With no previous drilling in this area and three EM conductors modelled from ground EM, this is viewed as a very positive result and the Company keenly awaits results of the DHEM survey prior to follow up drilling.
At Piega del West, 6 RC holes were drilled targeting ground EM conductors, as shown on Figure 6 . Rocks intersected in drilling where mainly basaltic, along with hornfels, sediments and granites in some holes.
Hole 20PVRC008 intersected elevated gold and silver (4m @ 0.34 g/t Au & 0.16 g/t Ag) associated with quartz veining in basalt, as well as 23m of elevated silver and manganese. Similar mineralisation was also intersected in 20PVRC009, and 20PVRC011 intersected 35m of elevated silver and manganese.
==> picture [451 x 91] intentionally omitted <==
Hole 20PVRC010 intersected a sulphide rich zone from 23 to 31m with elevated silver and locally anomalous base metals, which included:
4m@ 370ppm Cu, 35ppm Zn, 98ppm Co, 0.02 g/t Au, 2.04 g/t Ag, 0.28% Mn
Hole 20PVRC012 also indicated base metal potential with a sulphide rich zone from 110 to 115m returning:
5m@ 0.06% Cu, 90ppm Zn, 26ppm Co, 0.01 g/t Au, 2.25 g/t Ag, 0.74% Mn
Hole 20PVRC013 intersected low level sulphides from 116 to 118m:
2m@ 140ppm Cu, 0.05% Zn, 38ppm Co, 0.21 g/t Ag,0.3% Mn
While there were some areas of elevated sulphides, the Company does not believe these drilling intercepts adequately explain the conductors evident in the Moving Loop Electromagnetic ( MLEM ) survey at Piega del West. With signs of gold and base metals in the drilling, the Company will await the DHEM surveys to determine if strong conductors are present adjacent to or below the recent drill holes.
The hole drilled in the fold nose at Ponchiera Copper (20PVRC014) also returned quite strong first up results associated with basalts:
13m@ 0.16% Cu, 0.04% Zn, 85 ppm Co, 4 ppm Pb, 0.08 g/t Au, 0.25 g/t Ag from 109m
(including: 1m@ 0.68% Cu, 0.10% Zn, 145 ppm Co, 6 ppm Pb, 0.28 g/t Au, 0.85 g/t Ag from 115m )
Next Steps in the Exploration Program
Final assays from the recent drill program are expected in the next two weeks. The positive results from the new Perrinvale prospects supports a continuation of mapping and surface sampling with the aim of defining further drill targets.
The DHEM survey is expected to be completed within the next week, and these results will be integrated into existing datasets in order to assess further drill targets.
The Company’s DC drilling contractor, Westralian Diamond Drillers, are scheduled to return to site in the coming week, with a second deep hole at Schwabe initially planned. In addition, this will enable the Company to immediately move to testing any priority targets which are identified from the ongoing DHEM work.
Cobre’s Executive Chairman and Managing Director, Martin Holland, said in relation to the results from the third drilling program at the Perrinvale Project:
“The continued high-grade VHMS results at Schwabe are encouraging to see. In addition, we are pleased to have identified other VHMS potential in the area, which validates our strategy to unlock the full potential of the 381km[2] Perrinvale Project.
We expect to report additional assays shortly, with DHEM surveys also underway. Drilling will recommence with a second deep hole at Schwabe to further test the down dip potential. I look forward to providing further updates from the Perrinvale Project as they become available.”

Background on the Perrinvale Project
As a private company in June 2019, Cobre undertook an initial reverse circulation drilling program within the Perrinvale tenements to investigate targets identified by earlier exploration. At that time, the drilling program intersected very high-grade VHMS base metal & gold mineralisation at shallow depth. The best assayed intercept was at the Schwabe Prospect to date: 5m at 9.75% copper, 3.2g/t gold, 34g/t silver and 3.1% zinc from 50m depth[1] . Subsequently in August 2019, Cobre completed an airborne electromagnetic survey within the Perrinvale project area and identified a total of 10 potential VHMS prospects. Cobre was listed on ASX in January 2020. Since that time, Cobre has embarked on a systematic exploration program of RC and diamond drilling plus electromagnetic surveys in order to further investigate the VHMS potential of the Perrinvale area.

Section 1 Sampling Techniques and Data – Diamond Core & Reverse Circulation Drilling
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques | Nature and quality of sampling(e.g. cut channels, random chips, or specificspecialised industrystandard measurement tools appropriate tothe minerals under investigation, suchas down hole gamma sondes, or handheldXRF instruments, etc). Theseexamplesshould not be taken as limiting thebroadmeaning of sampling. |
Diamond drill core sampling was completed after core logging with the geologist defining sample boundaries based on lithology and observed mineralisation. Aimed at preventing mixing of lithologies, this approach does result in variable sample lengths at times. Where no signs of mineralisation were observed in hanging wall and footwall these sections of core were not comprehensively sampled. Core was cut perpendicular at the sample interval boundary and then cut in half longitudinally with one half put back in the core tray and the other in the pre-numbered sample bag. Reverse Circulation (RC) drill chips were collected directly from a cone splitter on the drilling rig and automatically fed into pre-numbered calico bags. All sample intervals are 1m, and the sample weight averages 3kg. The splitter and cyclone is cleaned and levelled at the beginning of every hole and cleaned at regular intervals during drilling. Observations of sample size and quality are made whilst logging. |
| Include reference to measurestaken to ensure sample representativity and theappropriate calibration ofany measurement tools or systemsused. |
The core to be assayed was taken from the same side looking down hole. Blank sample and bags for duplicates were inserted into the sample sequence. To increase representivity of duplicate samples, where a duplicate was inserted an empty pre-numbered sample bag was tied to the sample which was to be duplicated. At the laboratory,after the |

| half core was crushed the sample was split 50:50 with half retained as the original and the other half processed as the duplicate. Every sample is collected in duplicate direct from the splitter as drilling progresses, allowing for mineralised samples to be selected for duplicate assay. A series of coarse blanks is inserted at regular intervals. |
||
| 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. |
For core: Industry standard preparation, including crushing and full sample pulverising prior to subsampling for assay, was undertaken for samples up to 3.0kg. For samples over 3.0kg the sample was dried and crushed to -2mm then split in the laboratory to generate a <3kg subsample prior to pulverising to p85 75µm. The cut core samples were of varying weight with ~80% of samples greater than 3kg requiring splitting. 50 g of pulverized sample was utilised for gold determination via Fire assay with a AAS Finish, and a smaller subsample utilised for multi-element assay via Four Acid Digestion with ICP-MS Finish. For RC: Sample prep involved weigh, dry and pulverise to p85 75µm. Multi- element assay was by Four Acid Digestion and ICPOES. Gold was assayed by 50g Pb collection fire assay and AAS finish. For RC chip:full sample pulverising prior to subsampling for assay, was undertaken for samples up to 3.0kg. For samples over 3.0kg the sample was dried and split to generate a sub-3kg sample for pulverising to p85 75µm. 50 g of pulverized sample was utilised for gold determination via Fire assay with a AAS Finish, and a smaller subsample utilised for multi-element assayvia Four |

HQ2 & NQ2 core drilling was completed by contractor Westralian Diamond Drillers using a McCulloch drill rig. Where ground conditions allowed core was orientated using a Reflex ACT Orientation tool. RC drilling was completed by contractor Challenge Drilling using KWL 350 drill rig with face-sampling hammer, onboard 1100cfm /350psi compressor, and a 1000/850 booster compressor on separate truck. |
| Drill sample recovery | Method of recording andassessing core and chip sample recoveriesand resultsassessed. |
Soon after drilling core was laid out in individual core runs and Rock Quality Designation (RQD) measured and any core loss recorded on core blocks by the driller checked. No core loss in areas of sampling was recorded for the hole related to reported assays (20PVDD007). For RC drilling high air capacity ensured total and dry recovery. All bulk sample bags were visually assessed for volume consistency. |
