Work History
Staked as Eagle cl 1-32 (YA45031) in Jul/79 by Regional Resources Ltd, which carried out geological mapping, grid soil sampling and geophysical surveys later in the year. In 1980, the claims were optioned briefly by Amax of Canada Ltd which explored with more geophysical surveys. The property was transferred to Fairfield Minerals Ltd in 1988 but no additional work was reported.
Restaked as QB cl 1-28 (YB75490) in Feb/96 and QB cl 29-104 (YB83119) in May/96 by Nordac Resources Ltd. Nordac carried out geological mapping, prospecting, grid soil sampling and geophysical surveys later in 1996. During 1997 Nordac completed geological mapping, prospecting, grid soil sampling, excavator trenching and 994 m of diamond drilling in eight holes before staking QB cl 105-124 (YB90003) in Sep/97. In Sep/98, Nordac added QB cl 125-128 (YB91816) and carried out geological mapping, prospecting, grid soil sampling and hand trenching. Hand trenching was also carried out in 1999. In 2000 Nordac drilled 3 diamond drill holes (273 m), one hole tested the Main zone while the other two tested the West zone.
Nordac Resources Ltd was reorganized in Jun/2001 and renamed Strategic Metals Ltd.
Capsule Geology
The area is underlain by metamorphic rocks assigned to the Cassiar Platform and lies within a triangle formed by the Cassiar Batholith, Miester Lake Stock and the Marker Lake Batholith. These intrusions are mid-Cretaceous in age, unfoliated and range in composition from granite to granodiorite and less commonly quartz monzonite. Roof pendents of intruded schist and carbonate are present within some intrusions and thermal metamorphic aureloes surrounding the plutons are common and can extend up to several kilometers into the metasediments. The schists are generally unaffected but calc-silicate alteration is common in carbonate rich units. Well developed skarns have been mapped in several areas, usually within a kilometer of a pluton.
Soil sampling by Regional Resources outlined a 2 500 m x 1 000 m Pb, Zn, +/-Cu and +/-Ag soil anomaly that trends northeast across almost the entire length of the claim block. Follow-up prospecting located numerous pyrite rich, sphalerite-galena and chalcopyrite float boulders that returned up to 8.55% Zn, 1.44% Pb, 0.71% Cu and 2.98 and 102 oz/t Ag. Further exploration led to the discovery of the Discovery showing (this occurrence) which consists of sphalerite, galena and pyrite as fracture fillings in a biotite-muscovite-plagioclase-quartz schist. An IP geophysical survey conducted the following year outlined 5 IP anomalies, analysis of which suggested that large amounts of disseminated metallic mineralization was present.
Nordac Resources re-used Regional Resources original base line for their grid soil sampling program. The company obtained results similar to Regional Resources except that the strongest Pb-Zn response appears further to the west. Follow-up prospecting located 6 areas of sulphide rich float and 1 area (the Discovery showing) where sphalerite-chalcopyrite stringers were found crosscutting quartz-miuscovite chlorite schist. Ten pyrrhotite-pyrite-sphalerite-galena bearing float specimens collected across the length of the soil anomaly returned a arithmetic average of 9.98% Zn, 9.10% Pb, 0.13% Cu and 144 g/t Ag. Radiogenic lead isotope studies carried out on 3 high grade float samples suggests that the area has a potential for a manto replacement-type deposit. A ground magnetometer survey produced only erratic spot highs while a HLEM survey identified 4 subparallel conductors, each less than or equal to 400 m in length. One of the conductors lies along the north side of the main soil anomaly.
In 1997 Nordac dug 8 trenches (1 100 m total length) across those areas of the main soil anomaly which were accessable by the excavator. Four of the trench encountered intermittent bedrock while the other four bottomed in glacial till. None of the trenches which bottomed on bedrock encountered mineralization while the trenches that encountered glacial till returned float samples that contained either fracture or massive lead-zinc silver mineralization. Soil sampling extended the main soil anomaly to the west. The eight drill holes encountered either fracture filled, massive or semi-massive mineralization, usually within breccia zones located within limestone horizons. Hole QB-97-8 returned the best intersection which assayed 3.20% Zn, 1.52% Pb, and 25.2 g/t Ag over 11.93 m, including 13.55 Zn 8.43% Pb and 107.5 g/t Ag across 1.75m. Nordac felt that the massive sulphide intersections obtained from drilling were too narrow to adequately explain the abundant mineralized float observed throughout the property.
Grid soil sampling carried out in 1998 at the western end of the claim block outlined a 450 x 450 m area of strongly anomalous Pb, Zn, Ag and Cu response. Follow-up prospecting and hand trenching located 4 areas of mineralized float or outcrop where mineralization is associated with jasperiod altered limestone and consists of galena, sphalerite, chalcopyrite, pyrite and pyrrhotite plus secondary minerals in weathered material. A 15 m chip sample taken from one of the trenches returned a high of 151.1 g/t Ag, 2.52% Pb, 0.91% Zn and 0.34% Cu.
Nordac concentrated their 1999 exploration efforts on the western end of the property. Soil sampling was extended to better define known anomalies and several trenches started in 1998 were enlarged and deepened. After a literature search the company theorized that the bulk of the mineralization was hosted by a carbonate replacement deposit (CRD). CRD are epigenetic, intrusion related, high temperature, sulphide-dominant lead-zinc-silver +/- copper +/- gold deposits that typically form lenses, elongate pipies or elongate tabular bodies referred to as manto or chimneys.
In 2000 the company collared a single drill hole on the Main zone to test mineralized fault structures downdip from previous massive sulphide intersections associated with altered limestone wallrock. The hole cut several narrow faults within a chemically non-reactive schist underlying limestone, from which the best interval returned 14.0 g/t Ag, 0.65% Zn and 0.61% Pb across 1.25 m. The other two holes were collared to test mineralization present at the West zone. The holes showed that the rock units containing replacement mineralization outlined by hand trenching dip more shallowly than anticipated which severely limits tonnage potential of this target. The best of the two holes returned 39.9 g/t Ag, 0.73% Zn, 0.48% Pb and 0.18% Cu across 9.88m.
