Chase Mining Corporation Ltd (ASX:CML) has had VTEM plate models for priority sites within the Lorraine project in Canada confirmed by an independent peer review carried out ahead of the first drilling program.
The review by Perth-based Southern Geoscience Consultants (SGC) examined five priority-1 VTEM anomaly sites within the project area.
These five plate models comprising priority drill targets 1 to 5 were generated by Core Geophysics.
As first time ‘greenfield explorers’ in the Quebec Archaean terrane, the company deemed it prudent to commission SGC to undertake a peer review.
This showed that there is little difference in the plate locations between the Core and SGC models for targets 1, 2 and 4.
There are minor differences in dip and strike of the plates which may result in slight drill collar moves dependent on topography or changes in dip and azimuth of the holes.
The apparent size difference in the plates is due to the conductance levels applied to the plate.
Modelling of target 3 by SGC resulted in delineation of two smaller conductive plates versus a more continuous but lower conductance plate by Core.
The company has decided to test the western of the two SGC plates, which will also include the western end of the Core model, with a drill site to be positioned to test the eastern plate if needed.
Plate model for Targets 1 to 3.
At Target 5, the Lorraine Mine site, the company had instructed Core to target both the VTEM anomaly and an historical DHEM anomaly and SGC was also directed to provide drill collars to test both targets.
Pending access in relation to topography, the SGC drill collars will be used.
Orix Geoscience has completed digitising of the Lorraine Mine underground development – the deposit was mined through to surface and is now represented by the water filled pit in the image below.
The VTEM plate is located east of the shaft and may represent an unmined upper zone to mineralisation that was tested at depth by underground drilling from the ‘eastern drifts.
Finalising drill sites
Data entry for the Lorraine Mine ‘geology and mineralisation’ is in progress and an Orix crew will be onsite from today to finalise drill sites and access.
They will meet The Anishinabeg of Kakinwawigak (The Long Point First Nation) to finalise a permit for access to the exploration areas under their Indigenous Title and Rights.
Pending any unforeseen delays, drilling is still scheduled to begin in early August.
A peer review of the Alotta priority 1 VTEM anomaly is also underway with a view to selecting a historical hole for electromagnetic surveying (DHEM) later in the year or drilling a new hole to test the anomaly if prior DHEM is not possible.
