Hammond Reef South

The Hammond Reef South Project is about 3 km south of the Hammond Reef Deposit. The Hammond Reef Deposit is a large, low grade, shear hosted gold deposit which has open pit measured and indicated mineral resources estimated at 208 million tonnes grading 0.67 g/t gold (Agnico website, 2020).

The Hammond Reef South Property is underlain by the Archean Marmion Lake batholith, which is situated in the Wabigoon subprovince of the Superior Province of the Canadian Shield (Rennie, et al., 2009). The Marmion Lake batholith is dominantly felsic intrusive rocks varying from granite to tonalite. North-northeast trending faults splay off the east-west trending Quetico Fault and mark the western boundary of the batholith. Where they crosscut the Marmion Batholith the faults become diffuse and disseminated as braided anastomising zones of alteration with associated vein stockwork systems. This diffuse zone of alteration and mineralization is up to 6 km wide and hosts the Hammond Reef gold deposit. Gold mineralization occurs in quartz veins and stockworks within zones of sericite alteration.

The Hammond Reef south property is immediately adjacent to this zone and may contain extensions of the Hammond Reef zone or parallel structures. Agnico has staked a large area which completely surrounds the property, suggesting they consider the area prospective.

Exploration on the property, carried out from 2009 to 2012, consisted of widely spaced prospecting traverses and limited soil sampling. Significant mineralization was found just north of the property boundary by Osisko. Anomalous samples from this local returned from 0.18 to 4.75 grams per tonne Au. The area of the property immediately to the southwest (ie. along the usual trend of mineralization in the area) has had little exploration. Alteration and minor mineralization were located in other areas of the property as well, but the preliminary nature of the work has left much of the ground incompletely evaluated. 

A program of magnetometer and soil surveys, along with geological mapping and prospecting, is  recommended with the purpose of locating zones of Hammond Reef style mineralization on the Hammond Reef South Property.
