The first hole CM-19-06 at Lorraine was completed at 135 metres and was designed to intersect the modelled priority-one versatile time domain electromagnetic (VTEM) plate at a depth of 90 metres.
The hole ended in a 40-plus-metre gabbro body with minor sulphides but did not intersect a massive sulphide source that would explain the strong VTEM conductor.
Pending the outcome of hole CM-19-07 which is being drilled to a depth 350 metres, CM-19-06 will be deepened to test the footwall contact zone of the gabbro to host nickel-copper mineralisation as well as gold mineralisation.
Four holes to be drilled
This first hole was the lowest ranked target of the five priority-one targets.
While not locating the source of the strong VTEM conductor, encouraging lithologies that host nickel sulphide mineralisation mainly comprising of gabbro with altered variations plus mafic volcanics were intersected.
With correct nickel lithologies present the hole has been cased for possible follow-up downhole EM.
A downhole electromagnetic (DHEM) survey operating at a lower frequency is expected to provide better resolution of the high conductance priority-one VTEM.
Testing deeer gold potential
The second hole at Lorraine is currently at 111 metres depth with a target DHEM plate at 270 metres downhole.
Final depth will be 350 metres and the hole will also test the deeper gold potential of the target.
The drilling contractor has provided crew and equipment to establish an access trail to the first and second priority-one VTEM targets and are currently cutting a connecting trail to target three.
Consultants Orix Geoscience have positioned a portable core shack for logging and core-cutting facility at the base camp.
