The primary focus of the program was four holes (23MJ010-23MJ013) drilled to test for extensions to depth of the near-surface high-grade gold zone at the East Target.
Results confirm that gold mineralization extends deeper to the south, where the system plunges to the southwest and is very likely down dropped by faults south of the surface expression. These holes are the deepest expression of the East Target yet, with strong gold intercepts occurring at more than 250 metres below surface. Even though these holes were significant step outs to the south and southwest, the results demonstrate opportunity for expansion to depth and to the southwest.
Selected Highlights from the latest drilling at the East Target
Drill hole 23MJ013 intercepted: o 13.5m averaging 3.16 g/t Au, from 230.6m depth, including 1.0m at 18.42 g/t Au and o 1.0m at 5.31 g/t Au, from 271m depth and o 6.5m at 1.01 g/t Au, from 281.5m depth.
Drill hole 23MJ011 intercepted: o 3.6m averaging 5.96 g/t Au, from 236.3m depth, including 0.7m at 21.77 g/t Au and o 0.8m at 5.93 g/t Au, from 122.85m depth.
Five of the six drill holes encountered significant gold mineralization, as defined by intercepts above 0.5 g/t Au. The final two holes of the program (23MJ014 and 23MJ015) were collared in, or near, the
To date, most of the mineralization identified at Mustajarvi is hosted in metasedimentary rocks that have been intensely altered with albite, sericite, local silicification, sulfidation, iron carbonates, and/or cut by quartz-carbonate veining. High grades of gold are associated with quartz-carbonate-tourmaline-pyrite (QCTP) veins, hydrothermal breccias, or semi-massive to massive pyrite controlled by foliations. Gold is often enriched at or near the contact with mafic or ultramafic rocks. Until now, mafic rocks, either representing intrusive dikes and sills or thin layers within the Savukoski volcanics, have not typically been recognized as hosting significant gold grades. These new holes have encountered significant mineralization in numerous places within the mafic rocks, albeit so far at relatively low grades, such as 6.5m at 1.01 g/t Au in drill hole 23MJ013. The mineralized mafic rocks are usually intensely albitized with disseminated pyrite and cut by quartz-carbonate or QCTP veins.
Methodology & Quality Assurance
The core was transported from the rig to the Company's core storage facility in Sodankyla, where FireFox's exploration team conducted the geological and geotechnical logging and selected the assay intervals. Assay intervals were generally 1 metre but in some circumstances were modified according to lithological boundaries and other factors. FireFox geologists maintained chain of custody and sampling procedures according to best industry practice and with due attention to quality assurance and quality control, including sampling field duplicates and insertion of certified standard and blank samples.
FireFox team members transported the samples to an ALS sample prep lab in Sodankyla. The samples were sawed then crushed to -2 mm, split and pulverized into 1kg pulps, before being shipped to the ALS facility in
