CopperCorp Commences Maiden Drill Program at Dora Prospect targeting outcropping mineralization zones with up to 6.3% Cu, 47.7 g/t Au, 250g/t Ag, 2.25% Co, 5.5% Zn, 2.3% Pb in western Tasmania
VANCOUVER, BC February 21, 2023 – CopperCorp Resources Inc. (TSXV: CPER) (OTCQB: CPCPF) (“CopperCorp” or the “Company”) is pleased to report that it has commenced a 3-hole scout diamond drilling program at the Skyline Project, located 15km northeast of Queenstown in western Tasmania, Australia.
- A 3-hole, 750m scout diamond drilling program has commenced at the previously undrilled Dora prospect – a 5km long zone of outcropping IOCG style mineralization within the Skyline Project in western Tasmania
- Drilling will test under outcropping mineralization along the Dora trend where previous rock sampling1 has returned anomalous assays including up to 6.3% Cu, 47.7g/t Au,250g/t Ag, 2.25% Co, 5.5% Zn, 2.3% Pb, and 839ppm TREO from individual samples
- Dora Prospect is located near two large-scale mines that are within 5 km of the Skyline project boundary – the Mt Lyell Cu-Au deposit (3 Mt Cu and 3 Moz Au @ 1.0% Cu and 0.3g/t Au)2, and the Henty Au deposit (1.64 Moz Au @ 12.5 g/t Au)2
- The drill program is partially co-funded by the Tasmanian government
Stephen Swatton, President and CEO of CopperCorp commented:
“The commencement of a drill program at a highly mineralized zone close to, and potentially on strike from, a 3Mt/3Moz copper-gold deposit (Mt Lyell, New Century Resources) that has never been drilled before is significant and exciting. Our sampling of historical trenches returned spectacular results which replicated previously recognized copper-gold base metal zones coincident within a 5km series of highly magnetic north-northwest trending structures. We are also to report that the government of Tasmania has awarded the Company a grant to offset drilling and helicopter costs, a strong endorsement of the Company and the government’s recognition of the value of mineral exploration to the state’s economy. We will eagerly await assay results from the drilling which we expect in Q2 2023. The location of the project is in western Tasmania, a recognized multicommodity mining district, that benefits from cheap 100% renewable power, a skilled labour force and a technical service industry that supports the 6 nearby operating mines and numerous quarry operations.”
Planned Drill Program
The planned drilling program comprises 3 scout diamond drill holes totaling 750m, to be drilled from 2 pad locations approximately 1km apart that will test 2 priority targets (Dora 2 and 3) for IOCG style mineralization. The first drill hole will test the Dora 3 target area, while 2 holes will be drilled from the second pad to test the Dora 2 target area. The program may be extended depending on results of the initially planned holes. The drilling is helicopter-assisted (mobilization, supply, demobilization).
The first two drill holes of the planned program were successfully awarded co-funding under the Tasmanian government’s exploration drilling grant initiative (EDGI) scheme. The government contribution to each drill hole is up to $50,000 for direct drilling costs, plus an additional $20,000 for helicopter support.
About the Dora Prospect
The Dora prospect is defined by a northwest trending 5 km long zone of highly prospective outcropping polymetallic Cu-Au-(Ag-Zn-Pb-Co-REE) mineralization. The area saw a period of small-scale mining and prospecting between the years 1890 and 1920 but was then left unexplored until more modern times. Geological mapping and sampling of outcropping mineralization and historical small scale mine workings by previous explorers since the 1960’s and, more recently, by CopperCorp has led to 4 high-priority target areas being identified at Dora (see below). Despite evidence for a potentially significant Cu-Au system at Dora, the area has so far remained untested by drilling.
Dora 1 Target Area:
At Dora 1, anomalous assays from outcrop and historical workings occur over a +300m long, approximately 50m wide vein and breccia-matrix mineralized zone adjacent to a mapped quartz-feldspar porphyry intrusive. The mineralization is coincident with a magnetic high feature that extends over 1 km of strike length. Historical and recent anomalous rock sample assays from the Dora 1 area include:
- 3.2% Cu with 1.44 g/t Au, 42 g/t Ag, 1.7% Zn and 0.85% Pb.
- 0.2% Cu with 1.9 g/t Au, 16 g/t Ag and 885ppm Co.
- Numerous samples ranging 0.25-0.54% Cu, 0.12-0.47 g/t Au, 54-88 g/t Ag, 146-320ppm Co, 0.2-9.6% Zn, 0.4-2.1% Pb.
Dora 2 Target Area:
Dora 2, which lies adjacent to the southwest of Dora 1, comprises a +200 m strike zone of historical small-scale mine workings on mineralization hosted in an intrusive quartz-feldspar porphyry and adjacent altered volcaniclastic rocks. Historical and recent anomalous rock sample assay results from the Dora 2 area include:
- 47.7 g/t Au with 3.85% Cu, 2.25% Co, 250 g/t Ag and 0.46% Pb with visible erythrite (a cobalt arsenate mineral).
- 6.3% Cu with 2 g/t Au, 152 g/t Ag, 0.5% Pb and 0.4% Zn.
- 0.5% Cu, with 0.8 g/t Au, 115 g/t Ag, 5.5% Zn, and 2.3% Pb.
- Multiple samples ranging 0.1-0.4% Cu, 0.1-1.2g/t Au, and 3.0-132g/t Ag, with up to 138ppm Mo, 135ppm U and 836ppm TREO.
Dora 3 Target Area:
The Dora 3 target area comprises an elongate zone, some +500m in strike length (open), of outcropping mineralization in an altered volcaniclastic host rock sequence. Anomalous assays from historical and recent rock sampling in the Dora 3 area include:
- 1.03% Cu with 0.4g/t Au, 21g/t Ag and 0.13% Zn.
- 1.29% Cu with 8.0g/t Ag.
- 0.91% Cu with 0.3g/t Au and 11g/t Ag.
- 0.59% Cu with 0.19g/t Au and 14g/t Ag.
Dora 4 Target Area:
Dora 4 comprises a +800 m long northwest-trending line of outcropping mineralization and historical mine workings. Historical and recent anomalous rock sample assay results from the Dora 4 area include:
- 1.38% Cu with 9.3 g/t Ag.
- 0.78% Cu with 7.0 g/t Ag and 0.23% Pb.
- 0.68% Cu with 3.4g/t Ag and 0.14% Pb.
- 0.21% Cu with 0.1g/t Au and 15g/t Ag.
- Individual samples with up to 53g/t Ag, 2.4% Zn, 2.6%Pb, 473ppm Co and 608ppm TREO.
IOCG Prospectivity at Skyline
Cu-Au mineralization at the Dora prospect and wider Skyline project typically comprises vein and disseminated magnetite/hematite-pyrite-chalcopyrite in altered volcaniclastic and quartz-feldspar porphyry host rocks. Lesser minerals include bornite, covellite, chalcocite, native copper, native silver, galena, sphalerite, erythrite, cobaltite, and hematite. Malachite and/or azurite occur locally as oxidation products of chalcopyrite. Elevated concentrations of cobalt and rare earth elements are associated with the mineralization assemblage.
The hydrothermal mineralization system at the Skyline project is interpreted to be of magmatic-hydrothermal IOCG type in style1, associated with Cambrian aged magnetite-series, K-Ba-REE rich, alkaline granitoid-porphyry intrusives, and shows similarities to magmatic-hydrothermal IOCG systems of the Andean coastal cordillera (e.g. Candelaria deposit: 470Mt @0.95% Cu and 0.22g/t Au)1.
Alpine West Drilling Update
The maiden drilling program at the Alpine West prospect, 500m west of the Alpine Stellar zone, is currently ongoing and expected to be completed before the end of February. The drilling comprises 3 diamond core holes totalling approximately 1,550m. Samples from the first 2 holes are at the laboratory. Results will be reported following receipt of assays, review and interpretation.
AMC Regional Exploration
Recent data compilation and review work undertaken for CopperCorp’s AMC Project has identified 23 priority Cu-Au exploration target areas. The primary exploration target is for iron-oxide-copper-gold (IOCG) style mineralization, however, potential for other mineralization styles was also recognized during the review, including volcanogenic Cu-Au and intrusion-related Cu-Au and Ag-Pb. The Company’s exploration team has commenced ground activities (geological mapping and sampling) aimed to further assess and refine the exploration targets. Initial work has focussed at the Jasper Hills Cu-Au prospect (Figure 1) where initial reconnaissance has identified multiple historical mine workings and outcropping mineralization. This has led to a more detailed geological and sampling program at Jasper Hills which is currently ongoing. Results from the regional exploration programs will be release following receipt, review and interpretation of sample assay results.
New Tenement Application
A review of potential copper-gold opportunities in Tasmania identified open ground in the central north of the state with potential prospectivity for sediment-hosted stratiform copper mineralization. In order to facilitate a more in-depth review and assessment, the Company has secured the area, called the Whiskey Creek Project, under a tenement application (EL15/2022) submitted covering a 243 km2 area (see Figure 1). Notwithstanding any stakeholder objections to the application, it is anticipated that the tenement will be granted in the coming months.
