Work History

Staked as Howdee cl 1-16 (YA45711) in Sep/79 by Chevron Canada Ltd, which explored with prospecting, mapping and geochemical surveys in 1978-1980.
Restaked as Goal cl 122-319 (YB60658) between Oct/95 and Feb/96 by Expatriate Resources Ltd which carried out soil sampling, and prospecting later in the year. In 1997 the company carried out further soil sampling and prospecting, and in 1998 geological mapping, hand trenching and follow-up soil sampling and prospecting.

Capsule Geology

The Howdee occurrence lies within the Yukon-Tanana Terrane in the Finlayson Lake area. Geological mapping completed by Murphy and Piercey (1999) of the Yukon Geology Program shows that the occurrence area is predominantly underlain by the Devonian to Early Mississippian Fire Lake mafic metavolcanic unit (unit DMF). The mafic metavolcanics are overlain by the Mississippian Grass Lakes Succession comprised of carbonaceous phyllite (unit MKcp) and a small body of Kudz Ze Kayah felsic metavolcanic unit (unit MK). To the north and west, a large body of Devonian to Mississippian variably serpentinized ultramafic rock (unit DMum) intrudes the sequence near the base of unit DMF. Murphy and Piercey suggest that the ultramafic rocks are sills that flowed from dykes lying along the trend of thickness changes in unit DMF. A Cretaceous, granitic intrusion (unit Kg) intrudes the sequence to the east.
The occurrence consists of three mineralized areas, which Expatriate named (from south to north) the Chapman showing, the E1 zone and the E2 target area. The Chapman showing is one of two previously explored areas. It consists of scheelite mineralization within calc-silicate bearing, discontinuous limy bands. Scheelite and a trace of chalcopyrite were also found in two small, fault-related calc-silicate zones adjacent to quartz veins and silicified shear zones. Host rocks are quartz-muscovite schist and quartz-feldspar(± biotite) augen gneiss located near the margin of the Cretaceous intrusion. The 1978-80 work (mapping, soil sampling and soil panning) outlined tungsten anomalies associated with the Chapman showing and anomalies that could not be correlated to known mineralization. Analysis for tin produced only background values, but several samples returned between 20-317 ppb Au (Cathro and Schmidt, 1981).
The E1 zone, located about 1 km north of the Chapman showing, is defined by a 500 m long, copper soil anomaly (up to 430 ppm). The zone encompasses mineralization located in 1980, (Cathro, 1981) consisting of scheelite mineralization within a banded calc-silicate schist, apparently formed between the lime-rich host rock and a large quartz vein filled shear zone. Later work (Eaton, 1998) discovered malachite and azurite stained mafic metavolcanic float which yielded 1.4g/t Ag and 0.27% Cu. Minor disseminated pyrrhotite with trace amounts ofchalcopyrite, malachite and azurite, found in weakly limonitic quartz-biotite-muscovite schist and quartz-chlorite schist, yielded up to 1.4g/t Ag, 1 930 ppm Cu, 12 ppm Pb, 80 ppb Au and 2 800 ppm WO3 (Wengzynowski, 1999).
The E2 target area, located about 3 km north of the Chapman showing, covers a strong Cu +/- W soil anomaly and two mineralized showings, the Kel and the Crown. The Kel showing consists of disseminated pyrrhotite and scheelite in a narrow gabbroic dyke that returned 1.7% WO3 (Burgert, 1997). Later work (Eaton, 1999) noted localized concentrations of scheelite in quartz-actinolite veins, between 5-8 cm wide, within a southeast trending shear zone cutting across the dyke.
About 700 m west of the Kel showing, but still within the E2 target area, is the Crown Showing. It consists of a 600 m by 600 m soil anomaly which returned anomalous copper (<2 120 ppm) and tungsten (<480 ppm) values (Eaton 1999). The sample that yielded the peak values also returned 18.0 g/t Ag and 280 ppb Au. The area is underlain by chlorite schist and distinctive quartz-muscovite-chlorite schist. Both units are crosscut by quartz-actinolite +/-hornblende +/-tourmaline veins. Hand trenches dug on these veins, returned a high of 1 655 ppb Au, 99.8 g/t Ag, 2.29% Cu, 666 ppm Zn and 681 ppm Co from a 1-3 cm wide limonitic quartz rich horizon (Wengzynowski, 1999).
