Lithology

Lithology Comments

Nov 26, 2019 (Therese Pettigrew) - The Dillman Shear Zone, located within the mixed pillowed to gabbroic textured M3 zone, contains a small bluish grey quartz vein which is heavily mineralized with pyrite, and contains traces of very fine native gold (Assessment report 52F04SW0001).

Mineralization

Mineralization Comments

Nov 26, 2019 (Therese Pettigrew) - At the Dillman Shear Zone, stripping revealed a 5 to 15 cm-wide quartz vein heavily mineralized with pyrite, which was traced for about 40 metres along strike. The vein occurs within a zone of sheared and chloritized gabbro averaging 0.5 metres or less in width, striking 055 degrees and dipping between vertical and 85 degrees to the southeast. Very fine native gold was observed at several places within the quartz-pyrite vein. The shear and vein appear to pinch out at the eastern end of the trench, but to continue beneath overburden at the western end of the trench. Assay results range from below detection to 0.03 oz/ton gold in grab and chip samples of sheared wallrock. Chip samples across the shear and vein assayed from 0.004 to 0.587 oz/ton gold, with most falling between 0.02 and 0.138 oz/ton. Analysis of grab and chip samples consisting entirely of quartz and pyrite returned gold values ranging from 0.006 to 1.578 oz/ton, with most samples assaying about 0.50 oz/ton. One sample from the area (sample 220435) returned a value of 0.081 oz/ton gold from loose dioritic bedrock containing a few percent disseminated pyrite as smears along joint planes. About 300 metres southwest of the Dillman shear zone, sample 218770 assayed 1622 ppb (0.049 oz/ton) gold. The sample was obtained from a small, iron stained, quartz stringer hosted by a sheared quartz-feldspar porphyry dyke. The dyke occurs alongside and parallel to a major lineament extending southwesterly from Beadle Lake. The lineament is coincident with a major swamp to the southwest of sample 218770 (Assessment report 52F04SW0001).
