Avira Resources reported new assay results from recent drilling its Puolalaki project. Results for two more holes testing the newly discovered, near-surface massive sulfide mineralization returned 17.05m @ 0.70% Ni, 0.70% Cu and 1049ppm Co in drill hole PUO23007 and 19.4m @ 0.35% Ni, 0.39% Cu and 558ppm Co, including 4.43m @ 0.73% Ni, 0.71% Cu, 1063ppm Co in drill hole PUO23008.
DHEM surveying was further successful in identifying a 50,000Si off-hole conductor in drill hole PUO23010. The conductor appears to be coincident with a narrow zone of semi-massive sulfide mineralization within a broader mineralized interval.
In addition, the company conducted petrographic studies and mineral mapping via Scanning Electron Microscope-Energy Dispersive Spectroscopy on seven polished thin sections from the Puolalaki Ni-Cu-Co mineralization. The results showed that pentlandite and pyrrhotite are the main nickel and cobalt-bearing minerals and that pentlandite occurs as inclusions and voids/crack filling within the pyrrhotite.
