FireFox Gold Tests New Drill Orientation and Hits More High-Grade, including 13.09 g/t gold over 15.5m, at Mustajärvi Project, Finland
FireFox Gold Corp. (TSXV:FFOX)(OTCQB:FFOXF) announced promising results from its recent drilling at the Mustajärvi Gold Project in Finland. The first three drill holes from the fall 2022 campaign tested a new near-surface high-grade gold zone at the East Target, uncovering significant intercepts, including 15.5m at 13.09 g/t gold. All three holes confirmed the mineralization's expansion, showing improved grade and thickness compared to earlier drilling. The company anticipates results from two additional drill holes shortly. These developments are crucial for assessing the project's potential and enhancing shareholder value in the growing gold market.
- Drill hole 22MJ021 returned 15.5m at 13.09 g/t gold, indicating high-grade mineralization.
- All three drill holes revealed significant gold intercepts, confirming the presence of mineralization.
- The drilling program successfully extended the high-grade gold system at the East Target, improving depth and width.
- None.
SODANKYLÄ, FINLAND / ACCESSWIRE / January 18, 2023 / FireFox Gold Corp. (TSXV:FFOX)(OTCQB:FFOXF)("FireFox" or the "Company") is pleased to report results from the first three drill holes of the fall 2022 core drilling campaign at the Company's
Drillholes 22MJ021 and 22MJ022 both encountered significant high-grade gold at depths of less than 20 metres below surface. The best intercept in this round of results was 15.5m of 13.09 g/t gold in 22MJ021, which began just below the covering glacial sediments at 11m downhole depth. Importantly, these holes were drilled perpendicular to the drilling orientation favoured in the previous campaigns and appear to have successfully confirmed that the observed cross-structures host significant mineralization.
FireFox's CEO, Carl Löfberg, commented, "Our drilling at Mustajärvi East is yielding consistent improvement in grade and thickness of the gold mineralization. In addition to the continued presence of narrow bonanza veins, our most recent drillholes have encountered replacement style mineralization over greater widths than previously seen on the project. It also happens that these new robust intercepts lie at very shallow depths in the East Target. By drilling these new holes towards the northeast, we have expanded the footprint of the high-grade system to the west, to the north, and to depth. We anticipate results from two more holes in the East Target in a few weeks."
Highlights of selected intervals are shown below, while Table 1 includes all significant intercepts:
- 22MJ021: 15.5m at 13.09 g/t Au from 11.0m depth*, including
- 3.6m at 16.45 g/t Au from 14.4 metres depth, and
- 6.5m at 19.18 g/t Au from 20.0 metres depth, including
- 3.5m at 24.35 g/t Au from 23.0 metres depth
- 22MJ022: 7.2m at 16.43 g/t Au from 22.8 metres depth, including
- 3.0m at 37.9 g/t Au from 26.2 metres depth; and
- 1.7m at 31.6 g/t Au from 86.0 metres depth
- 22MJ023: 1.0m at 26.4 g/t Au from 53.0 metres depth
- 4.0 metres at 4.22 g/t Au from 89.0 metres depth, including
- 2.0 metres at 6.36 g/t Au
- 4.0 metres at 4.22 g/t Au from 89.0 metres depth, including
This drilling was prompted by the extraordinary results from drill hole 22MJ006, which returned 13.85m averaging 28.74 g/t gold from only 24 metres downhole (see Company news release dated September 6, 2022). Drill holes 22MJ021 and 22MJ022 were drilled perpendicular to 22MJ006 to test for lateral and downdip extension of the 22MJ006 mineralization. The third drill hole in this phase of work, 22MJ023, tested the expansion of the mineralized trend farther to the north. All three drill holes returned multiple significant intercepts including high-grade gold mineralization that are expected to expand the East Target laterally and at depth.

Mustajärvi Project and Drill Program Details
The Mustajärvi Project lies along the highway between the cities of Kittilä and Sodankylä, approximately 17 kilometres east of Kittilä. The property straddles the Mustajärvi Shear Zone (MSZ), a major right-lateral shear zone that has associated second and third-order structures which further dissect the project into separate structural zones. The Sodankylä Group rocks, which are primarily to the north of the shear zone in the footwall, include metamorphosed sedimentary and volcaniclastic rocks. Geophysics and drilling have identified an extensive corridor of albite - sericite alteration in the footwall along more than two kilometres of the structure. The project remains at an early stage as FireFox and predecessor companies have drilled approximately 12,594 metres to date.
FireFox's structural model identified repetitive dilatant zones along the MSZ where vein swarms and higher-grade gold are concentrated. Three main areas of gold mineralization have been identified along a 2.1-kilometre segment of the MSZ, namely the Central Zone, the Northeast Target, and the East Target.
During the year 2022, FireFox completed a total of 25 diamond drill holes for 3,904 metres at Mustajärvi, testing the Northeast Target, the East Target, the Gabbro Target and the Central Zone. The final program of the year included six holes totalling 977 metres, three of those holes are reported herein.
The East Target mineralization exhibits extensive albite - sericite alteration, as is typical along the MSZ, but iron oxide and iron carbonate veining are more common in this eastern part of Mustajärvi. The drill logs from the recent drilling also include increased reports of mafic volcanics interbedded with the metasediments and tuffaceous rocks that host most of the Mustajärvi mineralization. Gold continues to be closely correlated with the occurrence of pyrite. Similar to previously reported holes from the East Target, the near-surface gold mineralization from the most recent holes is associated with fractures and impregnation of (partially oxidized) pyrite along fractures, forming blebs, nests, disseminated, semi-massive and massive pyrite mineralization within the host rock. The thicker intervals reported in 22MJ021 and 22MJ022 present strong evidence of hydrothermal replacement of the host rock with quartz-sericite-pyrite + iron oxide. Pyrite can be seen to be replacing laminations and other sedimentary textures (See Figures 2 and 3).
Figures 2 and 3 - Albite-quartz (+ tourmaline) alteration with pyrite replacement at East Target (Click here to enlarge)
The deeper mineralized intervals include the more typical quartz-carbonate-tourmaline-pyrite (QCTP) veins that are commonly seen at Mustajärvi. The vein and replacement types of mineralization may be separate events, but the geochemistry is very similar - dominated by an association with bismuth, tellurium, molybdenum, cobalt, and nickel and low in arsenic and copper. There are at least two major directions of controlling structure on the Mustajärvi mineralization, east-northeast striking (parallel to the MSZ) and north-northwest striking (perpendicular to the MSZ). There are still results pending for two holes drilled along the northwest-southeast profile at the East Target, and FireFox geologists continue to study the relationship between the narrow high-grade veins and thicker replacement style of mineralization.
Hole 22MJ021 was designed to test the east-west extent of the near-surface, high grade gold mineralization identified in drill hole 22MJ006. The hole was collared approximately 28 metres west of 22MJ006 in thin glacial sediments overlying intensely altered intermediate tuffites, interbedded with mafic volcanic rocks.
The 28 mineralized intervals (>1 g/t gold) confirmed by the assays included both vein and replacement styles of mineralization, starting immediately below glacial till overburden at a depth of 11.0m and continuing to a depth of 94.65m (Table 1). The best interval reported above (15.5m averaging 13.09 g/t Au*) appears to be contiguous with the high-grade gold reported previously in 22MJ006 and extends that mineralization approximately 15m to the west-southwest. The results from the upper portion of this drillhole (11.0 to 27.5m) have been reported from a 1,000-gram screen fire assay protocol.
Hole 22MJ022 was drilled on the same profile as hole 22MJ021, approximately 40 metres to the southwest, and nearly 65 metres west of 22MJ006. Its east-plunging configuration was designed to undercut the shallow high-grade zone. It was collared in thin glacial sediments overlying intensely altered intermediate tuffites and lesser mafic sequences, and it intersected eleven intervals containing >1.0 g/t Au, starting at 20.1m downhole. The best interval started at 24.6m depth and returned 5.4m averaging 21.66 g/t Au, including 3.0 m at 37.39 g/t Au.
More importantly, hole 22MJ022 also intersected deeper high-grade gold mineralization at 86m, such deeper veins have not been commonly encountered to date at the East Target. This interval returned 1.7m averaging 31.6 g/t Au, including 0.7m at 55.06 g/t Au. The deepest interval from this hole was at a depth of 90.7m and included 2.0m averaging 6.13 g/t Au.
Hole 22MJ023 was drilled approximately 35 metres northwest of hole 22MJ022. The hole was collared in thin glacial sediments overlying intensely altered tuffites and metasediments. The hole intersected 8 narrow intervals that assayed above 1 g/t Au, including a deeper interval of 4.0m averaging 4.22 g/t Au starting at 89m. The highest-grade interval started at 53m and returned 1m at 26.4 g/t Au.

Notes: Drilling is believed to be perpendicular to the dip of the mineralization, however interval true widths are not yet known and will be confirmed with additional drilling and geologic modelling. In this table, the aggregate grade-thickness of the entire drill hole is provided. For each interval exceeding the 0.5 g/t Au cut-off, the interval thickness is multiplied by its gold grade, and the sum of all those intervals is reported as total Grade - Thickness in "gram - metres" of gold. * Intercept includes a total of 1.7m of core loss - one interval of 0.9 and another of 0.8m. Both intervals were near the top of the hole (above 14.4 metres downhole). These lost intervals were assigned a grade of 0.0 g/t Au for all calculations. | |||||

Methodology & Quality Assurance
The core was transported from the rig to the Company´s core storage facility in Sodankylä, 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 Sodankylä. The samples were sawed then crushed to -2 mm, split and pulverized into 1kg pulps, before being shipped to the ALS facility in Rosia Montana, Romania for gold by fire assay of 50 gm aliquots with AAS finish (method Au-AA24). Selected samples were assayed with a 1,000-gram Au-SCR24 method (screen fire assays). Other elements, altogether 48, were measured after four-acid digestion by ICP-AES and ICP-MS (method ME-MS61) at the ALS facility located in Loughrea, Ireland.
ALS Laboratories is a leading international provider of assay and analytical data to the mining industry. All ALS geochemical hub laboratories, including the Irish facility, are accredited to ISO/IEC 17025:2017 for specific analytical procedures. The Firefox QA/QC program consists of insertion of certificated standard material and blanks inserted by Firefox into the analytical batches did not show deviations from recommended values.
