Nic Capps P.Geo – Exploration Geologist, Marathon Gold

Nic is an experienced exploration geologist who has worked in the gold industry in Newfoundland for over 10 years. After graduating with Honours from Memorial University, he began working with Marathon Gold, where he has helped develop what is soon to be the largest gold mine in Atlantic Canada. Working through progressively more senior roles, Nic has been an integral part of bringing the company’s flagship Valentine Gold Project from a grassroots exploration project to the multi deposit, construction-ready project it is today.

Talk Abstract:

The Valentine Gold Project, located in central Newfoundland, is a structurally-controlled orogenic gold deposit consisting of qtz trml-py-Au (QTP-Au) veining hosted in the Valentine Lake Intrusive Suite (VLIS; 565-575 Ma). The VLIS lies in unconformable contact with the Silurian-aged Rogerson Lake Conglomerate (RLC) along the NE-SW trending Valentine Lake Shear Zone (VLSZ). Five phases of Acadian-aged deformation have been identified on the property, with gold mineralization associated with up to four orientations of QTP-Au veining, the dominant set being SW dipping and infilling extensional brittle fractures. Individual extensional fractures, as exposed at surface, can have a lateral extent of up to 50m.

The Project currently hosts five deposits with mineral resource estimates, including the Leprechaun, Marathon, Berry, Victory and Sprite deposits, as well as numerous other showings along the 20 km of currently explored strike of the VLSZ. Current exploration is focused on the newly discovered Berry Deposit. At Berry, as well as at Leprechaun, gold mineralization within the QTP veins appears controlled by large-scale (>20m) mafic dykes which run sub-parallel to the VLSZ, causing the mineralization to accrete in a concentrated band between these dykes and the Rogerson Lake Conglomerate to the SE. The Marathon deposit, which is the largest deposit currently on the property, hosts much more irregular, discontinuous mafic dykes. This appears to dictate a broader distribution of brittle deformation and QTP-Au veining, at a modestly lower average grade.
