Limestone/Marble Significance
The primary lithology that hosts gold mineralization at Fondaway Canyon is a thick sequence of bedded siltstone, shale, and mudstone.
At surface, northwest of the Colorado Pit is a block of limestone/marble, host to the historic Upper Quick-Tung tungsten mine (Figure 2). This limestone/marble block is one of a series of structurally bound limestone/marble units situated between two parallel NE-SW faults spanning the distance from the Colorado Pit to the Pack Rat gold zone.
Previous drilling has solely occurred to the southeast of this NE-SW corridor of limestone/marble blocks except for drilling within the area north of the Colorado Pit, that identified at surface high grade gold mineralization (refer to Company news release dated Sept. 23, 2025). Hole FCG25-36 is the first hole to extend the drilling to the northwest and target this untested region (Figure 2).
The results from hole FCG25-36 demonstrate that:
1.) High-grade gold mineralization has been discovered and occurs in contact with and to the northwest of (i.e. on the other side of) a limestone/marble unit;
2.) The limestone/marble units and structural setting may be a gold enrichment control feature; and
3.) The limestone/marble unit is itself mineralized with gold reporting an intercept grading 0.4 g/t Au over 14.8 m.
The key takeaway here is that the limestone/marble blocks and the NE-SW structural corridor that host them are not a limiting factor for gold mineralization, may well form part of a control feature for gold emplacement, and expansion of the mineral resource and open pit can be extended further northwest than currently modelled. This discovery provides additional encouragement and impetus for follow-up drilling in this region.
