The Ah Hoo Creek occurrence is located near the confluence of Ah Hoo Creek and the Germansen River.
This occurrence is hosted within the Permian to Pennsylvanian Manson Lakes Ultramafites. Mineralization consists of disseminated pyrrhotite and occurs in serpentinized ultramafic bodies within and near the Manson fault zone. A serpentinite sample assayed 0.19 per cent nickel (Open File 1989-12). Pentlandite and trace amounts of gold have been reported in this general area.
Work History
The primary showing on the Ah Hoo Creek property was first described in BC Minister of Mines Annual Report 1936: “At Ah Hoo Creek, a belt of serpentinite quite well mineralized with pyrrhotite is cut by the river. A sample assayed: Gold, trace; nickel, 0.18 per cent. Below this point, placer deposits usually contain small amounts of platinum.”
The area underlain by the Ah Hoo property was explored as part of the Flume project of Manson Creek Resources in 1983 and 1984. Mapping and sampling by the British Columbia Geological Survey in the late 1980s highlighted anomalous concentrations of indicator metals for platinum group elements in the Germansen River, below but not above Ah Hoo Creek itself, suggesting Ah Hoo Creek could be the source of the elevated platinum numbers.
During the 1983 exploration season, Manson Creek Resources (Assessment Report 12362) carried out reconnaissance geological mapping and geochemical sampling in the vicinity of the Ah Hoo occurrence. This sampling program was confined to two closely spaced, divergent lines along roadcuts 200 metres along the suspected strike from the occurrence. The first line consisted of 12 rocks and 5 soils taken at 1-metre intervals from sheared and altered serpentinite. The second line consisted of 11 soils at 5-metre intervals taken from a dark red, hematitic, sandy clay with abundant rock fragments, believed to be regolith. Although platinum values were not above background, one significant gold value of 0.85 gram per tonne gold was obtained, but not followed up.
During the late 1980s, the British Columbia Geological Survey undertook a regional mapping program in the Germansen Landing area to provide a detailed geological database for the highly prospective mineral area (Bulletin 91). This program included 1:50 000 mapping, revision of MINFILE, additional regional geochemistry and an attempt to place known mineral occurrences within a geological framework. Several serpentinite occurrences were sampled during the study, yielding values ranging from 0.20 to 0.25 per cent nickel. This program also located anomalous antimony, arsenic, chromium, and nickel values—indicator metals for potential platinum group metals—in stream geochemistry sampling.
In 2001, the Ah Hoo Creek property was staked by Tarmac Management Ltd to cover an occurrence of nickel with potential associated platinum group elements within ultramafic rocks in the Germansen Landing of central British Columbia. In 2003, a one-day visit was made to the Ah Hoo Creek property by geologist R. Tim Henneberry, who conducted a brief investigation of the area and wrote a geological report and planned a future work program (Assessment Report 27445).
In 2006, Spanish Mountain Gold Ltd conducted a comprehensive soil and silt sampling program on the MC property within the Manson Creek area covering approximately 54 000 hectares. In total, 962 soil samples, 52 silt samples and 52 heavy mineral samples were collected. Heavy mineral sample 791H046, located 600 metres southwest of the Ah Hoo Creek occurrence, was assayed with 93.4 grams per tonne gold (Assessment Report 29274).
In 2017, Angel Jade Mines Ltd. carried out a field program with the intention of locating hard-rock sources of placer gold, and to determine if gold and base metal anomalies within the listwanite exposures could be used as a vector to high-grade mineralization. The field program focused on three regions within the Manson Creek area, the Big Bend area near the southern extent of the claim group, the Gary’s Pit area within the eastern extent of the claim group and the Blackjack Creek area within the northern extent of the claim group. Between the three regions, a total of 62 rock samples were collected and assayed. The assays returned no values of economic interest and it was suggested that future exploration would benefit from structural mapping in locating the quartz-vein–hosted coarse gold.
