Rathbun Inventus is currently conducting a prospecting and mapping program at the high-grade Ni-Cu-PGE Rathbun sulfide occurrence. The sulfide occurrence was mined in the 1890s where a historic shaft is present. Past sampling by Inventus of the shaft area returned assays ranging from 6.3 to 74.4 g/t palladium, 1.0 to 18.4 g/t platinum, 0.8 to 22.8% copper, 0.1 to 0.5% nickel, 0.5 to 13.3 g/t gold, and 1.0 to 13.0 g/t silver.
The recent prospecting work has led to the discovery of a Sudbury-type breccia structure that hosts the sulfide occurrence and extends for at least 700 metres (Figure 2). Historic exploration efforts at Rathbun did not establish that the high-grade sulfide occurrence was a Sudbury-type mineral system. This breakthrough by Inventus has led to the successful identification of this complex geological system and its continuity along strike. Prospecting of the Sudbury-type breccia structure is currently ongoing, and the first assay results are expected in August.
