The Max (Bor) occurrence is located on the north west side of Corbold (Canyon) Creek, at an approximate elevation of 760 metres and approximately 15 kilometres north of the head of Pitt Lake.

The area is underlain by a roof pendant of pyritized, epidote and chlorite- altered feldspar-quartz porphyritic meta-andesite of the Middle Jurassic Harrison Lake Formation. The pendant is enclosed by Late Jurassic quartz diorite of the Tertiary to Jurassic Coast Plutonic Complex. These units are occasionally cut by steeply dipping porphyritic dykes striking north to northwest.

Locally, sulphide mineralization is developed in the north end of the roof pendant and in the enclosing quartz diorite to the west over a distance of more than 120 metres. Mineralization consists of pyrite, bornite, molybdenite and chalcopyrite as massive veinlets and as disseminations in a stock work of quartz veinlets. Pyrite, chalcopyrite and bornite are, also, locally concentrated along shear zones exhibiting sericite-kaolinite alteration and silicification.

In 1928, a chip sample of pyritic quartz veinlets is reported to have assayed 6.63 grams per tonne gold, 13.7 grams per tonne silver and 0.16 per cent molybdenum (Minister of Mines Annual Report 1928, p. 390).

In 1972, selected rock chip samples from a trench assayed 0.54 per cent copper and 17.8 grams per tonne silver, while a select sample of material from a stockpile assayed 10.9 per cent copper and 214.1 grams per tonne silver (Assessment Report 3906). The following year, a chip sample, across a 0.3- metre wide shear, contained 0.69 gram per tonne gold, 50.7 grams per tonne silver and 1.95 per cent copper (Assessment Report 4513, p. 7).

In 2012, samples are reported to have assayed up to 1.05 per cent copper and 7.5 grams per tonne silver (Assessment Report 33563).

The occurrence has been explored periodically since its discovery in 1928. During 1965 through 1967, programs of prospecting, silt and soil sampling, geological mapping and an airborne magnetic survey were completed on the area as the Max claims. In 1972 and 1973, Dunbar Resources completed programs of silt and rock sampling and geological mapping on the area as the Bor claims. In 1979, the property was submitted to Kerr Addison Mines Ltd. by Mr. Mel De Quadros, who owned the property. In 1984, Indian Gold Resources prospected and soil sampled the area as the Ultimate claims. In 2012 and 2015, Ivor Ventures completed programs of soil sampling and prospecting on the area.
