- Geological Details
- This mesothermal gold deposit is located about 900 ft (274 m) south of Phantom Lake.
The area of the showing is underlain by granodiorite which intrudes metadiorite and basic volcanics of the Amisk Group and is itself intruded by the Phantom Lake Granite. The mineralization is associated with a main fault which strikes 284° and dips 85°N to 70°S and a branch fault which strikes 335° and dips 50° to 70° E.
Along the main fault, the altered (silicified, chloritized, and carbonatized) and fractured hornblende granodiorite is cut by numerous stringers and narrow (up to 20 ft or 6.1 m wide) brecciated veins of white to grey quartz and chlorite-carbonate which contain pyrite, chalcopyrite, scheelite, and molybdenite. The only visible mineralization in the main fault is pyrite. The branch fault hosts scheelite, chalcopyrite, and gold mineralization. The mineralization occurs a few hundred feet west of the granodiorite-volcanic contact. The mineralized zone is discontinous along strike. Minor sulphide showings are common locally, near the contact.
One drillhole was completed on the ore zone and returned 0.01 to 2.84 oz./ton Au and 0.12 to 41.2 oz./ton Ag. surface samples in the area gave 0.01 oz./ton Au, 0.12 to 0.48 oz./ton Ag and 3.43% Cu.
A trench close to hole No. 9 was channel sampled and returned 7.58 oz/ton Au and 7.30 oz/ton Ag over 12 cm. A 30 cm channel sample taken from the shaft returned 18.80 oz/ton Au. A 1 m channel sample taken nearby returned 6.54 oz/ton Ag.
The grade of ore shipments was 1.30 to 3.78 oz/ton Au and 2.5 to 4.7 oz/ton Ag. 2015 prospecting and rock sampling program for gold in the Phantom Lake area. Grab sample 2608 (83/13, 6063292 N, 701204 E) of silicified granite with pyrite stringers in an old trench with an analysis of 1.61 g/t Au. Grab sample 2617 (83/13, 6064107 N, 700854 E) of silicified pyritic granite with an analysis of 1.10 g/t Au. Grab sample 2621 (83/13, 6064060 N, 700876 E) from a silicified pyritic granite in an old trench with an analysis of 13.75 g/t Au. Grab sample 2624 (83/13, 6063065 N, 701481 E) of a cherty, pyritic granite with an analysis of 3.02 g/t Au. High grade values were also returned from sheared, pyritic granite from a shaft dump pile.

- Exploration History
- 6/23/1988 The property was first staked as the PHANTOM claim in 1921. Between 1936 and 1937, Mr. Graham completed minor trenching in the showing (AF 63K12-0037). The claims were brought to lease by Mr. R.E. Graham in 1952.
In the winter of 1933, ore was taken from a quartz lens for flux at the Flin Flon Smelter. In 1942 a sample from the property submitted to the Mines Branch in Ottawa, assayed 1.04% WO3. Tanton reported tungsten in a gold-bearing quartz vein and drill core.
Reported development work by 1960 consisted of the sinking of a single-compartment vertical shaft to a depth of 40 ft (12.2 m), one large trench, and 10 small trenches and pits. In this year, 13 tons of ore were mined.
In 1965-66 the International Minerals and Chemical Corp. (Canada) Ltd. DAN and DEE claims covered the area. A program of geological mapping, prospecting and sampling and limited diamond drilling of 1 hole totalling 26 ft (7.9 m) was conducted. Samples returned the values listed above. An EM survey was conducted in 1965. Both EM and Mag surveys were conducted by Semiahmoo Petro-Mines in 1970. By 1979, the showing was within JERRY claim No. 8. In 1983, the showing was covered by CBS 3182. In 1985, SMDC completed reconnaissance geological mapping and rock and forest litter sampling over the property (AF 63K12-0144). Samples from showing trenches returned up to 0.032 oz./ton Au, 2.5 ppm Ag, >4,000 ppm Cu and 100 ppm Zn.
By 1986, the showing has been staked as S-96187. In 1986, SMDC completed ground VLF-EM and magnetic surveys over the Phantom grid (AF 63K12-0147) and geologically mapped the property (AF 63K12-0150). In the following year, SMDC completed further ground EM and magnetic surveys on the Phantom grid which covered the showing (AF 63K12-0164).
In 1998, Callinan Mines Limited optioned CBS 3182 and completed ground TDEM and magnetic surveys over the claim block (AF 63K12-0206).
- Production History
- Production Period: 1960-01-01 to 1960-12-31
13.00 tons
In 1960, one ton of hand sorted ore was taken from the third trench north of the shaft and 12 tons of hand sorted ore were taken from the shaft. This ore produced an average grade of 2.35 oz/ton Au and 3.56 oz/ton Ag.
Summary:
- Gold @ 2.35 oz/ton
- Silver @ 3.56 oz/ton
Production Period: 1933-01-01 to 1933-12-31
500.00 tons
In the winter of 1933, 500 tons of quartz was mined from a quartz lens on the property. The quartz was shipped to the Flin Flon smelter for flux.
Summary:
- Quartz: 500.00 tons
