The area is underlain by several phases of dioritic to gabbroic rocks, that intrude Amisk Group basalt to andesite flows and pyroclastic rocks. The Tartan Lake deposit consists of two gold-bearing shear zones: the Main zone and the South zone. The Main zone does not outcrop; however, the South zone is well exposed and is characterized by a central zone of chlorite-carbonate-quartz, fuchsite, tourmaline, sericite schist, a marginal zone of weakly schistose chlorite-carbonate-quartz and an outermost zone of pale green, schistose to weakly schistose, chloritic rock. Fine-grained, massive gabbro with weak carbonate alteration is found at the margins of the shear.
Most of the property's reserves are confined to the Main zone shear and consist of two gold-bearing lenses that strike 090, dip steeply to the north, and plunge steeply west to northwest (Northern Miner, January 20, 1985; Kreczmer and Deveaux, 1986). Lens number 1 has a strike length of 60 m and extends vertically to the 90 m level. Lens number 2, which is located 5-10 m on the footwall side of lens 1, has a strike length of 40 m near surface, increasing to 200 m long, on the 200 m level.
Gold was found on two adjacent claims on the east side of the narrows, at the bend in Tartan Lake. Flin Flon is approximately 13 km SW of these claims.
Killarney (P87) and Monica 2 (P214) were staked in 1931 by T. Creighton and E. Tahey, respectively. The following year, Consolidated Mining and Smelting Company of Canada Limited did surface work on the west side of Killarney and optioned Monica 2. Assays from Killarney yielded $1.80 Au over 15 ft. and up to $100.20 Au across 1 ft. Hudson Bay Mining and Smelting Co. Limited sampled Monica 2 and found from $2.20 Au over 3 ft. to $2.80 Au over 7 ft. (Brownell, Unpublished Information File).
By the end of 1933, 14 pits and trenches had been put down on the two claims. Some of this work may have been done by Ventures Limited, which located a zone assaying up to 102 grams/tonne (g/t) (3 oz Au/ton) over narrow widths (Northern Miner, Sept. 28, 1945). In 1939, Killarney was leased as
Nesnah Mining and Exploration Company Limited took an option on Killarney in 1945. Nesnah traced a mineralized shear across three claims. In the autumn of 1945, the company began X-ray diamond drilling on Monica 2. One 3 m (9.7 ft.) core section averaged 23.62 g/t (0.689 oz/ton) Au. At least 37 holes were drilled by the time drilling ceased in 1946. Most of this was done in exploration of the extent of the high-grade intersection, found the previous year. Reserve estimates, based on 1100 m (3600 ft.) of diamond drilling, were 64 t (70 tons/ft) per vertical 0.3 m, averaging 19 g/t (0.56 oz/ton) Au or 90 t (100 tons) per vertical 0.3 m (1 ft.) grading 14 g/t (0.416 oz/ton) Au. The best section returned 260 g/t (7.58 oz/ton) Au across 0.3 m (1 ft.) in a 3 m (9 ft.) section, which averaged 29 g/t (0.847 oz/ton) Au (Nesnah Corp. File).
The later histories of the claims are tabulated below:

In September 1981, Granges Exploration Aktibolag staked CB 12297 over the property. Granges, in joint venture with Scandinavian Minerals Syndicate (SMS) and Aberford Resources, carried out diamond drilling. In May 1984, they announced the discovery of significant gold mineralization. Hole 43 had intersected 17 m (55.2 ft.) averaging 21g/t (0.6 oz/ton) Au, with one 3m (10.5 ft.) section averaging 77 g/t (2.25 oz/ton) Au. From May 1984 until the Tartan Lake mine went into production in May 1987, Granges and joint venture partner Abermin Corporation (formerly Aberford Resources), carried out an extensive diamond drilling ore delineation program. The program outlined reserves of 465 000 t (513 000 tons) at a grade of 12 g/t (0.349 oz/ton) Au (Northern Miner, January 12, 1987).
In early 1986, the joint venture partners commenced work on the first phase of their property development plan with the construction of a 29 km (18 mi.), all weather road. Work on the underground program began in April with development of a decline. The second phase of development included assembly of a 454 t (500 ton) per day mill, the extension of the decline to the 244 m (800 ft.) level and the extraction of a 908 t (10 000 ton) bulk sample from the "Main Zone". In June 1987, the mine went into production, at a rate of 227 t (250 tons) per day. Mill throughput was expected to jump to350 t/day by September 1987 and 454 t (500 tons) per day at an annual production rate of 1338 kg (43 000 oz) per year, by the end of 1987. Capital cost of the project was $20.5 million.
In 1988, Granges started an expansion plan with the goal of increasing recovery by 90%, however, the expansion was delayed with the discovery of water problems underground, as well as false grading reports due to the presence of nuggets (Northern Miner, April 4, July 4, 1988). In the same year, Abermin had been asked to pay its share of outstanding joint venture costs. When Abermin failed to meet that payment, under the joint venture agreement the interests in the mine shifted to 60% Granges and 40% Abermin. In late 1988, after an unprofitable 4 years, Abermin rescinded from its joint venture agreement with Granges and totally dissociated itself from the property (Northern Miner, November 28, 1988). Shortly after, Abermin filed a lawsuit stating that the company was led to believe the grading and forecasts were higher than they actually were and was seeking the $17 million that they invested in the project and/or damages (Norther Miner, September 5, 1988).
In 1989, following the introduction of Granges to the American and London Stock Exchange, Granges Exploration Ltd. changed its name to Granges Inc. Shortly afterwards, production was put on hold at Tartan due to excessively low gold prices.
In 1990, the British Columbia Supreme Court ruled in Grange’s favour, awarding the company 100% interest in the property, as well as a $5 million settlement. Abermin had declared bankruptcy during the lawsuit (Canadian Mines Handbook, 1991-1992).
The property remained on hold until Granges began a new 3000 m drilling program in 1994. This program resulted in the discovery of a new gold zone, 100-200m southwest of the main zone, with mineable resources standing at 375 000 t ore grading 6.27g/t Au (Canadian Mines Handbook, 1995-1996).
In 1996, Granges amalgamated with Da Capo Resources Ltd., on a share for share basis, to form Vista Gold Corp.
From after the amalgamation in 1996 to 1998, Aur Resources may have held Tartan. Aur purchased a group of properties from Granges in this period, but it is unknown if Tartan was included.
Claude Resources Ltd. acquired Tartan in 1998, however as of 2002, no further work has been done on the property (Claude Resources Ltd., Annual Report, 2001).
