The Sylvan occurrence is located on the western slopes of Birkenhead Peak, approximately 3 kilometres south of Birkenhead Lake.

The property is underlain by a large northwest trending roof pendant of Upper Triassic Cadwallader Group rocks. These rocks have been intruded by at least three phases of the Jurassic to Tertiary Coast Plutonic Complex, consisting here of diorite and granite.

On the Sylvan claim, massive pyrrhotite and pyrite occur adjacent to limestone and the margin of intrusive rocks. Two mineralized zones are exposed over a 21.5-metre wide face of an opencut. A grab sample from one of these zones assayed 46.6 grams per tonne (Assessment Report 15409).

In 1994, the area was explored as part of the Bank claims of Donegal Developments. Exploration work included prospecting, geological mapping, geochemical and geophysical surveys. The area was explored as the Tex property in 2002 with 243 metres of diamond drilling in four holes on the nearby Texas occurrence (MINFILE 092JSE002). In 2007 through 2011, Homegold Resources completed various programs of geological mapping, geochemical sampling and prospecting.
