The Tez SE occurrence is located at an elevation of approximately 1060 metres on the north side of a small hill, approximately 3.3 kilometres west of the west end of Hatdudatehl Lake.
The area is underlain by andesite tuffs and minor flows of the Upper Triassic Inzana Lake Formation (Takla Group), which have been intruded by small monzonite plutons. Tuffaceous units range from thinly bedded fine muddy tuffs through massive fine-grained lithic tuffs to cherty lapilli tuffs.
Locally, a quartz biotite intrusive hosts narrow, 2-centimetre wide, quartz-carbonate veins with pyrite, chalcopyrite, galena and sphalerite mineralization.
In 2018, a rock sample (PZR-11) assayed 0.152 gram per tonne gold, 38.3 grams per tonne silver, 0.214 per cent copper, 0.316 per cent lead and greater than 1.00 per cent zinc (Assessment Report 37964).
Work History
The area was first staked as the Tez claims in 1989 by Rio Algom who is reported to have conducted an airborne magnetic survey, though this was not filed for assessment. In 1990, Rio Algom explored by mapping and a 2191-sample grid soil geochemical survey.
The SAS 1 claim was prospected in 1995 by Don Johnson, who collected 28 rock and 15 soil samples. In 1996, Johnson collected 17 rock samples and, in 1997, he collected a further 24 soil and 11 rock samples (PAP RPT 1996-33; 1997-10).
In 2005, Uwe Schmidt prospected his Carmen claims, which were staked to cover the lapsed Tez claims of Rio Algom and some of the lapsed SAS claims of Johnson. A total of 11 rock samples, 1 deep till sample and 1 soil sample were collected in 2005.
In 2008, Strongbow Exploration Inc. completed a program of rock, silt and soil sampling on the area as the Inza property. The following year, a program of rock sampling, geological mapping and 22.0 line-kilometres of induced polarization and magnetic surveys were completed on the property.
In 2011, Xstrata Canada Corp. completed a program of prospecting, geological mapping, soil sampling, an induced polarization survey and nine diamond drill holes, totalling 1946.3 metres, on two magnetic anomalies on the Inza property. Six of these drillholes were located on the hill side a short distance east of the Mustardo occurrence.
In 2018, John B. Kreft completed a program of rock and soil sampling on the area as the Tez property.
