Trek Metals Limited (ASX: TKM) has confirmed potential for a ‘significant’ VMS system from maiden drilling at the Valley of the Gossans prospect, within its 100%-owned Pincunah Project in the Pilbara.
The company reports that the nature, grade, and depth of the copper and zinc mineralisation have strong geological similarities to DEVELOP Global’s Sulphur Springs Copper-Zinc Project located 25km to the east.
“we now have enough evidence to be very confident that the Valley of the Gossans Project is likely to be large-scale VMS copper-zinc base metal system”
The VMS-style mineralisation was confirmed in bedrock below the 2km long soil anomaly recently defined by Trek, where 13 holes for 2,662m of RC drilling were completed.
Key drill results include:
- Hole VRC001: 88m @ 17.0g/t Ag from 0m Inc. 4m @ 223g/t Ag from 20m
- Hole VRC006: 25m @ 6.70g/t Ag from 112m Inc. 3m @ 0.75% Cu from 121m; and 20m @ 4.17g/t Ag & 1.48% Zn from 171m Inc. 1m @ 5.99% Zn from 171m & 6m @ 3.76% Zn from 184m
- Hole VRC008: 7m @ 0.99% Zn from 149m
- Hole VRC009: 70m @ 7.39g/t Ag from 0m Inc. 2m @ 0.40% Cu & 0.2g/t Au from 46m
Commenting on the results Trek Metals CEO Derek Marshall said: “The laboratory results have confirmed the positive indications from our maiden drill program at Pincunah that we announced in late July. The key takeaway for investors is that we now have enough evidence to be very confident that the Valley of the Gossans Project is likely to be large-scale VMS copper-zinc base metal system with an extensive footprint that extends over 2km.
The assays show that we intersected multiple horizons of classic VMS-style mineralisation and alteration, with highly anomalous zinc, copper and silver, plus multiple pathfinder elements that suggest we are right in the middle of a very fertile volcanic environment.
The geological similarities to the Sulphur Springs Project, located 25km to the east, which is currently being developed by DEVELOP Global, are striking and show that we are in the right sort of environment to make a significant VMS-style base metal discovery. The typical ‘clustering effect’ which is commonly associated with VMS fields further supports this potential.”
Trek says that it is now actively exploring, with soil sampling in progress to define the extents of the system. A helicopter EM survey has been scheduled for late October to define ‘significant’ conductive bodies related to massive sulphide mineralisation as immediate drill targets. The company is also planning to commence follow-up drilling ‘as soon as possible’.
