The Maybee A occurrence is located on steep south facing slopes north of the South Kal-Anch River, at an elevation of approximately 880 metres, 27 kilometres northwest of the town of Gold River.
The area is underlain by Upper Triassic Karmutsen Formation (Vancouver Group) pillow lavas with minor interbedded limestone, which have been intruded by granodiorite of the Jurassic Island Plutonic Suite.
Locally, a zone of sulphide-bearing cherty mudstone occurs near a strong north-south fault. Mineralization consists of lenses of brecciated sulphides consisting of galena, pyrite, magnetite and sphalerite.
In 1990, sampling yielded up to 2.255 per cent lead, 6.6 per cent zinc, 70.9 grams per tonne silver and 0.3 gram per tonne gold; while a 1.4 metre chip sample (8908270) assayed 1.794 per cent lead, 18.9 grams per tonne silver and 0.3 gram per tonne gold (Assessment Report 20079).
Scattered areas of skarn with minor sulphides are reported to the east.
In 1965, Empire Development completed a program of prospecting and geological mapping on the area as part of the Nimpkish Copper property. In 1972, First National Mines completed a program of geological mapping and rock sampling on the area as the HK 1-2 claims. In 1990, the area was prospected as the Maybee A claim. In 1993, Noranda completed a program of airborne geophysical surveys on the area as part of the Muchalat property. In 1995 and 1996 the Maybee A area was prospected, stream sampled and rock sampled by Westmin Resources Limited, operating for Doromin Resources Ltd. on the Dragon property.
In 2011, the area was prospected as part of the Preston property. In 2012 and 2103, Santa Fe Metals Corp., on behalf of British Pacific Minerals Ltd., carried out programs of prospecting, stream sediment and rock sampling on the Preston property. The sampling of mostly metasedimentary rocks returned anomalous values of copper (ranging between 0.0002 and >1 per cent) and silver (ranging between <0.1 to 3.3 grams per tonne). The sampling was followed up by a small microdrill program to determine the extent, style and potential of copper, silver, zinc, lead mineralization at the massive sulphide lens in Campbell Creek (092E 025), approximately 2.5 kilometres northeast of the Maybee A showing.
