Geology within the Longrose project comprises metasedimentary bedrock (greenschist facies) primarily meta-sandstone or meta-siltstone, (greywacke) which is weakly to moderately foliated. Other units include: meta-conglomerate (Figure 2) which is strongly foliated, polymictic, with boudin-like quartz relics, which are most likely the granite clasts from the conglomerate or possibly earlier stage quartz veins which were elongated. Conglomerates are typically a good host rock for Archean gold deposits.

The project area is mapped as having been subjected to at least two phases of folding which now lie recumbent (on its side) as is evident in the BIF unit exposed on the access road (Highway 580), beside the historic Leitch Gold Mine, see Figure 4. The metasedimentary package within the project also includes a banded iron formation known as the Southern Iron Formation.

Mineralization at the Longrose gold project is associated primarily with shear zones that are often silicified and strongly foliated. Sulphides include pyrite and pyrrhotite and occasional arsenopyrite, chalcopyrite is rare. The Leitch Mine to the immediate northeast produced 850k ounces gold up until the 1960s.  Five other deposits/showings are located along the Southern IF to the east, toward Geraldton Ontario.

The Longrose project is located within the broader productive and highly mineralized BGGB where several high-grade mines with average grades well above 15 g/t gold are noted (4.1M ounces of past production). The current targets at Longrose has this type of tenor and upside along strike for both banded iron formations and pyrrhotite rich shear zones (magnetic high features and shear zones with sericite and magnetite destruction show clearly as breaks in the broader magnetic fabric).
