Potential for Sediment-Hosted Copper Identified in Drilling at Whisky Creek Project
Vancouver, October 10, 2023 - CopperCorp Resources Inc. (TSXV: CPER) (OTCQB: CPCPF) ("CopperCorp" or the "Company") is pleased to announce an exploration update on its recently granted and 100%-owned exploration licence EL15/2022 (Whisky Creek) located in northern Tasmania, Australia.
Highlights
- Review of historical exploration data and drill core from the recently granted1 243km2 EL15/2022 (Whisky Creek) has confirmed excellent potential for sediment-hosted copper style mineralization at the project.
- Host rock sequences and mineralization styles indicate strong similarities to sediment-hosted copper deposits of the Central African Copperbelt.
- Limited diamond drilling in the early 1980's by Geopeko Ltd included best results of:
- 10m @ 1.0% Cu from 123m, including 1m @ 3.4% Cu from 123m; and 1m @ 4.1% Cu from 132m (DH10)1
- No significant exploration work at the project over the past 40 years.
- Planning and permitting for historical drill core re-sampling and field exploration programs underway.
EL15/2022 (Whisky Creek)
The Whisky Creek property, covering 243km2 of ground in northern Tasmania, was formally granted on 26th June 2023 for a period of 5 years (renewable). The property was originally identified and applied for by the Company during April 2022 following a review of potential open-ground copper-gold exploration opportunities in Tasmania. The Company recognized that the property holds potential for sediment-hosted copper and volcanic hosted sulphide styles of mineralization and opted to apply for the exploration license in order to review and further assess the property's exploration potential.
The volcano-sedimentary host sequences in the Whisky Creek project area are considered as correlates to the Cambrian aged Mt Read Volcanics belt of western Tasmania which is host to multiple word class copper-gold and polymetallic base metal deposits, including the Tier 1 Mt Lyell Copper deposits (3Mt contained copper). With practically no significant exploration effort at Whisky Creek over the last 40 years, the area has remained overlooked for its potential to host significant copper and/or base metal deposits.
Historically, the project area was prospected from the late 1800's to early 1900's with numerous prospecting and small scale mine workings located throughout the area. In modern times, the most comprehensive exploration effort was carried out by the Pennzoil-Geopeko JV during the period 1973 to 1982. Most of this exploration was focused on the Titania prospect area (historically known as the Dial mine grid), where ten wide spaced drill holes, totaling 1,506m, were drilled over a 1.5 x 1km area. The final drill hole of the program, DH10, intersected significant copper mineralization in favorable host stratigraphy (see below). No follow-up exploration or drilling was conducted on the project following the discovery.
Geology and Mineralization
The Whisky Creek project area covers a Cambrian rift basin (the Dial Range Trough) that was progressively filled by a complex succession of basal conglomerates and clastic sandstones, mudstones, carbonaceous to pyritic shales and siltstones, diamictites, basaltic volcanics, carbonates, and volcaniclastic sediments, which are considered highly prospective for a variety of sediment-hosted copper deposits. The depositional environment is considered of similar style to the copper deposits of the Central African Copperbelt.
A recent review of open file historical exploration data and drill core by the Company has shown that wide-spaced drilling carried out during the early 1980's intercepted anomalous copper mineralization in the Titania copper prospect area (Figure 1), with best results including 10m @ 1.0% Cu from 123m (within a wider zone of 20m @ 0.7% Cu from 117m), and including high-grade intervals of 1m @ 3.4% Cu from 123m, and 1m @ 4.1% Cu from 132m, including 0.5m @ 7.3% Cu from 132.5m, from drill hole DH102.
The mineralization in DH10 shows features strongly characteristic of sediment-hosted copper styles of mineralization, including stratiform disseminated and vein type chalcocite with lesser digenite, cuprite, covellite and pyrite hosted in a unit of interbedded laminated siltstone-shale and fine-grained sandstone (Figures 2, 4 and 5), and probably of early to late diagenetic timing. The mineralized siltstone-sandstone unit in DH10 immediately underlies a thick sequence of oxidized, strongly gossanous diamictite breccia (Figure 3) that exhibits textures evident of relict sulphide mineralization. The original sulphide content of the diamictite is estimated at 2-10%2 but is now completely leached or replaced by iron oxide minerals. Despite the extensive leaching and oxidation, the diamictite remains elevated in copper, averaging 630ppm Cu over its basal 60m in drill hole DH10, with intervals up to 0.13% Cu.
The sedimentological feature of interbedded sandstone-siltstone and diamictite sequences is characteristic of mineralized host sequences of the rift basin related sediment-hosted copper deposits in the Central African Copperbelt, including at the giant Kamao-Kakula deposit where mineralization is concentrated at the basal contact of the Grand Conglomerate diamictite and underlying siltstone-sandstone units. Interestingly, the discovery hole at Kamao (DKMC-RC159) assayed just 1.32% Cu over 12metres3.
The broader prospective volcanic-sedimentary rift basin stratigraphic package occurs over a combined strike length of 30km within the Whisky Creek project area and remains largely under-explored.
Next Steps
CopperCorp has commenced compilation and review of historical exploration data and has inspected available historical drill core as part of a review of the exploration potential of the Whisky Creek property. Planning and permitting for field exploration programs and re-sampling of historical drill core for full multi-element assaying is underway.
