Cosmo’s latest sampling with cracking new tech has picked out two strong, off-hole and shallow conductors just ahead of maiden drilling of the Minjina Prospect at its Yamarna Copper-Nickel-Cobalt project.
Recent geophysical data is suggestive of a juicy, widespread copper anomalism at the project in Western Australia’s Eastern Goldfields.
Cosmo Metals (ASX:CMO) says the recently completed analysis on an August MLEM survey at the belt’s Minjina Prospect was designed to follow up a downhole EM (DHEM) anomaly associated with historical drillhole 17MVRC004 which intersected this beauty:
- 12m at 0.8% zinc, 3.3g/t silver & 0.16% lead from 48m including 2m at 2.13% zinc, 3.56g/t silver & 0.39% lead from 58m.
The underexplored Yamarna Belt, is considered highly prospective for copper-nickel-cobalt (as well as platinum group elements) and the company remains focused on the advancement of its flagship Mt Venn, Winchester and Eastern Mafic projects.
Cosmo’s August DHEM survey at 17MVRC004 and hole 17MVRC0019 (~400m to the east) identified a strong off-hole conductor untested by drilling.
The company says this conductor is associated with widespread copper anomalism identified in surface sampling, and to constrain the modelling and reveal the strike extent of the DHEM anomaly a MLEM survey was collected over Minjina with four lines collected using an ARMIT sensor.
The ARMIT sensor is designed to operate with lower noise levels than other EM technologies and is considered better able to penetrate conductive cover and potentially to deeper levels below the surface.
A delighted Cosmo Managing Director, James Merrillees says this is the first time that an ARMIT sensor has been used at Yamarna and modelling and interpretation of the MLEM survey was completed in collaboration with geophysical consultants Newexco Exploration.
Two, 300m deep angled drillholes have been planned to test these targets and an additional five holes have been sited to test for less conductive (but potentially mineralised) positions up-dip of and along strike from the two modelled conductors.
Review of the anomalies revealed that the northern anomaly (modelled plate 9300_1 lt) is also associated with a discrete magnetic high which is interpreted to represent a more pyrrhotite-rich part of the Minjina target.
The southern anomaly (8900_1 lt) is interpreted to be a continuation of the Mt Venn orebody, ~300m north of the nearest drilling at Mt Venn.
Coming drilling
Cosmo’s boss says the RC drilling program will kick off next week at Minjina and potentially other high-priority targets from ongoing interpretation of the CMO October MLEM program.
“The Cosmo team is excited to be out drilling again testing high priority targets at the Minjina prospect, less than 1km to the north of Mt Venn,” Mr Merrillees says.
“The strong, late-time conductors associated with surface and drilling geochemistry, on the doorstep of Mt Venn has thrown up a compelling new target for Cosmo, and underlines the rationale for the January IPO, with a well-funded, technically driven team focussed on uncovering further base metals discoveries in the highly prospective Yamarna region.”
