The 330 km2 Goliath Gold Complex demonstrates numerous highly prospective targets that show potential to host gold mineralization including about 65-km prospective strike along trend from the Goliath, Goldlund and Miller deposits. The Goliath Gold Complex is located in the Archean Eagle-Wabigoon-Manitou greenstone belt in the Wabigoon Subprovince of the Superior Province.

Approximately 20 km east of the town of Dryden, the Goliath deposit is hosted within a 100 to 150 m thick unit of intensely deformed and variably altered, fine- to medium-grained, muscovite-sericite schist and biotite-muscovite schist with minor metasedimentary rocks. Native gold and silver are associated with finely disseminated sulphides, coarse-grained pyrite and very narrow light grey translucent “ribbon” quartz veining. The main sulphide phases are pyrite, sphalerite, galena, pyrrhotite, minor chalcopyrite and arsenopyrite and dark grey needles of stibnite. The alteration consists of primarily sericitisation and silicification in association with the gold mineralization.

At Goliath, the gold-bearing zones strike from 090° to 072° with dips that are consistently between 72° and 78° south or southeast. The mineralized zones are tabular composite units defined on the basis of moderate to strongly altered rock units, anomalous to strongly elevated gold concentrations, and increased sulphide content and are concordant to the local stratigraphic units. In the Goliath deposit, higher grade gold mineralization occurs in shoots with relatively short strike-lengths (up to 50 m) that plunge steeply to the west. The main area of gold, silver and sulphide mineralization and alteration occurs up to a maximum drill-tested vertical depth of ~805 m, over a drill-tested strike-length in excess of 2,500 m. The mineralized zones remain open at depth.

The Goldlund Deposit is situated approximately 35 km northeast of the Goliath deposit. Historical gold production from the Goldlund and Windward mines is reported to be 18,000 oz of gold, with mining activities carried out between 1982 and 1985 using both open pit and underground mining methods.

Gold mineralization is hosted by zones of northeast-trending and gently to moderately northwest-dipping quartz stockworks, comprised of numerous quartz veinlets less than 1 to 20 cm thick. The quartz stockwork veins consist of two synchronous sets of veins, referred to as the 20 set and the 70 set (Pettigrew, 2012), and display a remarkable consistency in form across the project.  The stockwork veins are hosted within albite-trondhjemite to diorite (granodiorite) strata-parallel sills, which strike generally northeast (065°) and dip from vertical to -80° southward, ranging in thickness from 14 m to 60 m. The stockwork zones form bands within the granodiorite sills that intrude the east-northeast-trending mafic metavolcanic rocks. The quartz veins and veinlets contain occasional fine-grained to coarse-grained pyrite. The intervening areas between the quartz veinlets exhibit strong to moderate feldspathic alteration associated with common fine- to medium-grained pyrite and magnetite.

The gold mineralization has been interpreted as a series of northeast-trending sub-parallel bodies. Mineralized zones 1, 7, and 5 consist principally of gold mineralization associated with the stockwork veins in the large granodiorite sills, while the other Zones consist of gold mineralization associated with stockwork veins that are hosted in several lithologies including andesite, and felsic to intermediate porphyries, with only a minor contribution from the granodiorite sills.
