CopperCorp Resources (TSXV:CPER) has announced new assay results from the Alpine prospect, a part of the AMC Copper Project location in Tasmania, Australia. The results are free seven diamond drill holes at the prospect, with the 1,066km2 AMC project. The first round of drilling at the Alpine Stellar zone is complete, and the company has drilled 16 diamond holes with a total of 5,490m. The drill program included infill and step-out holes to test the extent and continuity of the mineralizing system at the project. It also aimed to find new vectors to be able to target high-grade portions of the system.

The company has now moved the drill rig 500m to the Alpine West zone and has already begun drilling at hole AP037 to target a combined magnetic-gravity anomaly and coincident copper in soils anomalous zone. The company has interpreted this to be a possible strike extension to the Alpine Stellar zone mineralizations. 

Assay results for drill holes AP028, AP029, AP030, AP031B, AP032, AP033 and AP034 have also been received, with most of the seven holes successful in intersecting zones of significant copper mineralization.

Highlights from the results are as follows:

  • Significant mineralized intercepts from the recently received drill core assays include:
Hole ID Interval (m)1 From (m) Cu (%) Co (ppm)
AP030 26.2 85.8 0.53 191
And 37.0 181 0.57 271
including 10.0 185 1.20 488
And 18.0 307 0.70 238
Including 4.9 312.1 1.50 329
AP033 32.5 270.5 0.59 268
And 82.2 347.3 0.33 102
including 10.5 419 0.75 43
AP034 31.6 177.7 0.64 200
including 5.0 187 2.06 308

1Note that true widths are uncertain. Initial interpretation by the Company is that the copper mineralization is hosted in steeply dipping zones of mineralization implying true widths in the range of 70% to 95% of reported intervals. See full intercepts in Table 2.

  • High-grade intercepts, including 10.0m @ 1.2% Cu and 4.9m of 1.5% Cu in AP030, and 5.0m of 2.06% Cu in AP034, indicate the potential for accumulations of higher-grade copper within the larger Alpine Stellar target area, including to depth.
  • These results continue to define multiple broad, sub-parallel dipping zones of mineralization at the Alpine Stellar zone with average copper grades in the 0.3% to 0.7% range.
  • Recently completed deep drill holes AP035 and AP036 (assays pending) both successfully intersected intervals of significant visual copper sulphide1 mineralization up to 200m below previous drill holes.
  • Copper mineralization at the Alpine Stellar zone has now been defined over a strike length of 600m and to a depth of 400m from surface. The mineralization remains open at depth and along strike.
  • A geological review of the Alpine Stellar zone has commenced ahead of finalizing 3D models that will be used to plan future extension drilling at the Stellar zone.
  • The drill rig has been relocated to the Alpine West target, located approximately 500m along strike to the west from the Alpine Stellar zone. Drilling of AP037 has commenced on this previously untested target as the first hole of an initial scout drilling program comprising 4 diamond holes at Alpine West.

Sean Westbrook, CopperCorp’s Vice President of Exploration, commented in a press release:

“The recent drill results from Alpine Stellar zone have delivered strong copper intercepts over significant widths, and importantly, we are starting to see more high-grade intervals from drilling as our knowledge base develops and we vector towards the stronger parts of the Stellar system.

Encouragingly, recent drill holes AP035 and AP036, targeting depth extensions beneath previously drilled mineralization, have both intersected significant intervals of what we think is visible copper sulphide mineralization. The team eagerly awaits the assay results from these holes, which will be reported once received and reviewed.

The Company is pleased to have commenced drilling at the Alpine West prospect which will represent the first ever drilling at this location, which is approximately 500m west along strike from the Stellar zone. Alpine West is an exciting target with the potential to significantly expand the mineralization footprint at Alpine.

In conjunction with the Alpine West drilling, the exploration team has commenced a geological review of the Stellar zone ahead of finalizing 3D geological models that will form the basis for the next round of drill planning at Stellar. As demonstrated by the recent drill results, the Stellar zone holds excellent exploration upside potential and future work programs will be designed to vigorously pursue this growth upside. In terms of a growth story, it is still early days for Alpine and as can be seen in the drill section figures, increased drill hole density has a marked positive impact on defining higher-grade mineralization zones at Stellar.

On a district scale, it is pertinent to note that the currently drilled Alpine prospect area covers less than 1% of the IOCG prospective Arthur Metamorphic Complex (AMC), which has a strike length of 100km and over which CopperCorp holds a dominant tenement position with 1066km2 in granted tenements (see Figure 15). The Company has identified a pipeline of multiple regional copper and gold exploration target zones along and adjacent to the AMC trend and we look forward to reporting on these in the coming months. Field reconnaissance sampling was recently commenced over high priority regional targets with first assay results expected within 4 to 6 weeks.”
