Plato Gold Announces Results of 2-Hole Drill Program on the Marriott Gold Property, Matheson, Ontario - Seite 2

The presence of typical characteristics of gold deposits such as anomalous sulphide and base metal content, breccia, faults, quartz veins and secondary minerals indicates that the property has the potential to host gold mineralization. Next steps for Plato Gold are to follow up the 2023 drill program with another drill program with deeper holes along the same geophysics’ anomalies and geology units.

The presence of breccias in rocks are fluid pathways for hydrothermal fluids enriched in gold and base metals. Drill hole PG-23-1 is characterized by the presence of blue breccia from 181.62 to 196.85 m, 15.23 m interval with black clasts up to 10 cm in diameter rimmed and veined by an unknown secondary silicified blue mineral (Figure 1 and Figure 2). The blue mineral is possibly blue quartz, as it is hard and does not react to hydrochloric acid. The brown fine-grained matrix contains up to 35% sulphides and has pervasive chloritization.

Faults are also fluid pathways for gold and base metals. Drill hole PG-23-2 is characterized by the intersection of 5 fault zones: three fault zones are obvious in gabbro and massive basalt (13.9-15 m, 78-79 m and 166.6-168.4 m) and two faults are possible in massive basalt (139-140 m and 140.8-141.1 m).

Late-stage hydrothermal quartz veins and secondary minerals are typically present in Abitibi gold deposits. Quartz veining with carbonate-epidote-sericite-chlorite ±hematite occurs in both drill holes at Marriott. Quartz veins are typically up to 1 cm wide. The longest quartz vein intersection in drill hole PG-23-1 is 118.9-119.3 m, 0.40 m interval (Figure 3). The longest quartz vein intersection in drill hole PG-23-2 is 30.32-30.6 m, 0.30 m interval (Figure 4). Drill hole PG-23-2 has secondary purple fluorite with epidote and sulphides in brecciated basalt from 134.2-135.36 m, 1.2 m interval (Figure 5).
