The Thesis II occurrence is located about 400 metres southeast of the AL (Thesis II/III) past producer (094E 091) approximately 295 kilometres north of Smithers.

The Adoogacho and Metsantan members of the Lower Jurassic Toodoggone Formation (Hazelton Group) underlie the property. The Adoogacho Member consists of trachydacite ash-flow tuff with lenses of lapilli tuff, rare marlstone, and conglomerate near the base. The Metsantan Member is composed mainly of trachyandesite (latite) flows with lenses of lapilli tuff, and lahar; minor volcanic sandstone and conglomerate (Bulletin 86). The Metsantan Member, in part, directly overlies the basal Adoogacho Member and is also in fault contact with it. For a more detailed account of the local geology and alteration refer to the Bonanza occurrence (094E 079).

The Thesis II occurrence lies about 400 metres to the southeast of the Thesis III and is considered to be controlled by the same structure. See the Thesis III occurrence (094E 091) for more details. The Thesis II occurrence is underlain by andesitic volcanic rock of the Toodoggone Formation.

On surface, the Thesis II showing consists of a central core of quartz-limonite-hematite breccia which splays to the northwest. The silicified core is flanked by intensely argillic altered porphyritic andesite. The exposed zone is 150 metres long and has a maximum width of 50 metres. Barite is present but not abundant at surface and in drill core. Higher gold values are associated with hematite and limonite fracture fillings and breccia matrix. The silicified, brecciated core of the occurrence has a vertical to steep southwest dip with a southeast trend. Trace chalcopyrite and galena have been observed. Gold grades and mineralized widths in drillholes steadily increase to the southeast; the southeasternmost drillhole intersected 10.1 metres (true width) grading 4.38 grams per tonne gold (Assessment Report 15735).

Micromine Consulting's 2007 resource estimate for the Thesis II zone, using "uncut" gold assays and a cut-off grade of 3.5 grams per tonne gold is 18,340 tonnes grading 5.01 grams per tonne gold (Bowen, 2012).

See Bonanza (094E 079) for further geological and work history details of the Thesis II prospect. This prospect is presently (2014) contained within the Ranch (Al) property, along with a number of other prospects. See also the Nearby Thesis III occurrence (094E 091).
