Newrange Gold Corp. (TSXV: NRG) has released an update on its exploration projects in the Red Lake District of Ontario and the Walker Lane Trend of Nevada.
North Birch Project
At the North Birch Project, 110 kilometres northeast of Red Lake, two diamond drill holes were completed for a total of 723 metres. Although the winter drill programme was expected to include additional holes, highly variable weather forced a late start and early conclusion.
The holes were drilled to test a folded sequence of Iron Formation (IF) and volcanic rocks in a structural setting similar to the Musselwhite Mine, 190 kilometres to the northeast.
Newrange previously reported in March 2022 that hole NB22001 intersected a deformation zone more than 100 metres wide that had been interpreted from geophysics and LiDAR surveys. The hole collared in massive to pillowed Fe-tholeiitic basalt and shearing started approximately 200 metres downhole, becoming more intense with depth.
The basalt becomes increasingly magnetic downhole and laminated IF first appears at 421 metres. Folding is apparent in the IF and both basalt and IF display moderate to intense carbonate alteration and local quartz veining. Pyrite and pyrrhotite mineralization occur as disseminations, stringers and, locally, as ‘clots’ within quartz veins and veinlets.
Gold and copper assays increased downhole as shearing intensified. Values were geochemically anomalous, with high values of 0.25 g/t Au and 363 ppm Cu, and the relationship of gold and copper to shearing, quartz-carbonate alteration and pyrite-pyrrhotite mineralization are all encouraging signs considering that this horizon has never been drilled before.
Not only does Newrange control about eight kilometres of this horizon but this first hole stopped in highly sheared IF at 460 metres (vertical depth of approximately 320 metres) as the drill had reached its depth limitation. Follow up holes will be drilled in the opposite direction due to the local topography and the sub-vertical dip of the zone.
Hole NB22002 was drilled 800 metres along stratigraphic strike to the northwest to test coincident magnetic and Induced Polarisation anomalies. The hole was drilled to 263 metres at -50°, in massive to pillowed basalt and mafic tuff.
While the anomalies were explained by the presence of chalcopyrite-pyrrhotite stringers, which returned no significant gold assays, a zone of strong biotite alteration with highly anomalous trace element geochemistry was intersected just below this zone, indicating strong hydrothermal activity.
The deformation zone and IF intersected in the first hole were not seen in the second hole indicating that this structure does not appear to follow exactly along the main limb of the fold but likely trends closer to the central axis.
“We are very encouraged by the presence of strong deformation, alteration, and anomalous geochemistry in the initial holes at North Birch,” President and CEO, Robert Archer, said.
“Considering that this horizon is not exposed at surface and has never been drill-tested before, these are all positive indicators that are common to gold systems elsewhere in the Uchi Sub-province. We look forward to follow-up drilling to better understand the overall setting.”
Argosy Gold Mine Project
Due to weather challenges and resulting shortened drilling season, no holes were drilled on the adjacent Argosy Gold Mine Project this past winter. However, the first drill sites have been prepared and the initial holes will test both the down-dip extension of gold mineralisation below the historic mine workings and in parallel, un-mined veins closer to surface.
Management has conducted an in-depth analysis of results to date on the Pamlico Property in Nevada, including an in-house (not NI43-101 compliant) assessment of the Merritt Decline Area and other exploration targets on the property. Following a comprehensive strategic review, which appropriately considered current market conditions and high holding costs, the Board of Directors has concluded that the continuation of the project is no longer in the best interest of shareholders and has terminated the option agreement.
As part of the afore-mentioned strategic review, Newrange is actively reviewing several potential acquisition targets in order to maximise shareholder value.
The Board is committed to finding a new flagship project that will have the potential to provide significant upside. Discussions are ongoing in this regard and the company will inform shareholders of any progress in a timely manner.
