Work History

Staked as 328 Marylou cl (YA45065) in Aug/79 by Getty Can Mls L, which performed mapping and geochem sampling in 1980. Restaked as 22 Uno claims (YB49293) in June and Sep/94 by Cash Resources Ltd. Cash Resources carried out a week of prospecting and soil and rock sampling on the claims in Aug/94.

Capsule Geology

Massive pyrrhotite and pyrite with lesser galena and sphalerite and rare chalcopyrite, arsenopyrite and molybdenite occur in pods up to 5 m long in three semiconformable sericitized shear zones which cut a 12 m thick calc-silicate bed. Minor scheelite is present in podiform bodies and layers up to 1 m thick in a 10 m thick section of diopside calc-silicate.
Scheelite, with associated lenses of pyrrhotite and sphalerite, is mostly restricted to hedenbergite-rich skarns whereas more distal garnet and wollastonite-rich skarns are unmineralized. The calc-silicate rocks and skarns strike 120° and dip 45° north, and form part of a sequence of hornfelsed Cambro-Ordovician clastic sedimentary rocks near the contact of a 400 m wide porphyritic biotite quartz monzonite dyke of Cretaceous age. A chip sample assayed 454 g/t Ag, 1.0% Cu, 5.0% Pb and 2.0% Zn across 2 m.
The Uno claim block is located on the southeast edge of the Selwyn Basin geological terrane. A major thrust fault separates Cambrian to Ordovician Road River Group sediments from allochthonous paracratonic rocks of the Cassiar Platform located approximately 1 km to the south. The claims lie in the upper plate of a southwest-dipping thrust fault that surfaces 2 km north of the claim block. The thrust fault is truncated downdip by a regional-scale high angle fault located 1 km south of the claims. Both faults strike approximately parallel to the axial fold trend.
Road River Group which underlie the claims, consists of thin to thick interbedded, maroon, rusty weathering pelitic hornfels; white to grey-blue, buff and rusty weathering quartzite; and grey to pale green, thinly laminated chert. Carbonate rocks are typically interbedded with chert and consist of thin bedded, strongly bleached, white to pale green calc-silicate hornfels with local skarn zones.
A Mid-Cretaceous elongate stock 2.5 km long and up to 300 m wide trends east-west across the property. Most of the stock is comprised of fresh non-foliated quartz-monzonite but in places grades into porphyritic biotite granite. The intrusion cuts obliquely across the strike of the sediments and generally exhibits sharp contacts. It produced a thermal metamorphic aureole, the extent of which has not yet been determined.
Two types of mineralization are present: 1) semi-massive to massive sulphide lenses and breccia fillings; and, 2) sulphide stockworks. Both are best developed within moderate to strongly bleached quartzite beds. Veins and skarn zones are also present but appear to be small and sporadically mineralized.
Massive sulphide lenses contain coarse-grained pyrite>galena>arsenopyrite>chalcopyrite>sphalerite>pyrrhotite. A 1 m chip sample collected previously by Getty Mines returned 633 g/t Ag, 12.5% Pb, 1.05% Cu, 0.18% Zn and only minor Au. Float boulders of similar mineralization collected by Cash Resources in 1994, assayed up to 853 g/t Ag, 18.7% Pb, 4.50% Zn, 1.66% Cu and 400 ppb Au.
The sulphide stockwork is also occurs in quartzite. Sulphide-filled fractures comprise 20 - 39% (by volume) of the mineralized stockwork and contain coarse-grained pyrite>galena>sphalerite>chalcopyrite>arsenopyrite>pyrrhotite. Outcrop samples collected by Cash Resources from the West Zone returned up to 289 g/t Ag, 7.35% Pb, 0.12% Zn, 0.09% Cu and low Au values (5 ppb) while float samples collected by Getty Mines and Cash Resources from the East Zone yielded up to 73.0 g/t Ag, 1.42% Pb, 2.72% Zn, 0.26% Cu, and low Au values (<5 ppb).
Cash Resources collected the majority of their soil samples on the east side of the cirque located in the east-central part of the property where previous work by Getty outlined a strong Ag-Pb-Zn-Cu anomaly. Soil geochemistry outlined a moderate, 450 by 150 m northwest-trending, Au anomaly coincident with the northern edge of the stock. Relatively uniform, moderately to strongly anomalous Cu response occurs over the granitic stock. Five soil samples collected off grid lines in gullies suspected of containing vein faults returned strongly anomalous values for Ag-Pb-Zb-Cu but near background response for Au. Individual values were as high as 175 ppm Ag, >10 000 ppm Pb, >10 000 ppm Zn, 300 ppm Cu and 17 ppb Au.
