The Moosehorn Zone occurrence is located on Moosehorn Creek, approximately 1.5 kilometres north of its confluence with the Toodoggone River, approximately 288 kilometres north of Smithers.

The area is situated within a Mesozoic volcanic arc assemblage that lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Tertiary sediments, volcanics, and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins. Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. These Takla rocks have been intruded by plutons and other bodies of the mainly granodiorite to quartz monzonite Early Jurassic Black Lake Suite and are in turn unconformably overlain by, or faulted against, Lower Jurassic calcalkaline volcanics of the Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults, which define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high-angle northeast striking faults (approximately 060 degrees) appear to truncate and displace northwest striking faults. Collectively, these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

Locally, a 450-metre-wide zone of strong silica and potassium feldspar alteration reportedly contains pervasive quartz stockwork, quartz breccias, banded quartz veins, and chalcedonic quartz veins within Jurassic porphyritic intermediate volcanic flows (Metsantan Member, Toodoggone Formation) that are locally hydrothermally altered and mineralized (pyrite).

Historic work on the Moosehorn claims consists of limited shallow diamond drilling, silt, soil, and rock geochemistry and ground induced polarization geophysics performed mostly by Cyprus Metals in the mid-1980s. A historic one metre chip sample from this zone returned a grade of up to 3.2 grams per tonne gold and 125 grams per tonne silver (http://www.towerresourcesltd.com).

In 2011, Tower Resources acquired the property and completed a program of geochemical sampling, geological mapping and six diamond-drill holes, of an 18 hole drill program, totalling approximately 3000 metres.
