The Tchentlo occurrence is located in generally flat terrain in north-central British Columbia, 890 metres northeast of Tamasgale Lake, approximately 80 kilometres northwest of the community of Fort St. James. Access to the property is by helicopter, float plane or boat with the closest active logging road four kilometres to the main target area (ca. 2011).
The area is underlain by the southeastern end of the Early Jurassic Hogem Plutonic Suite, here consisting of an Early Jurassic monzonite phase. The monzonite is in contact with volcanic and sedimentary rocks of the Upper Triassic Inzana Lake Formation (Takla Group), to the south.
From 1966 to 1972, West Coast Mining and Exploration and Boronda Exploration Corporation Limited conducted geochemical and geophysical exploration for porphyry copper deposits. Later, Westmin Resources Limited carried out an airborne magnetics-VLF-HEM survey (1989), multi-element stream sediment and soil geochemistry (1989-1991), geological mapping (1989-1991), trenching (1990) and geophysics (1991). During this period, Westmin collected at least 118 rock, 52 silt and 3885 soil samples. Geophysical surveys include 49.7 kilometres of IP and 18.1 kilometres of ground magnetics.
Serengeti Resources Inc. acquired the Tchentlo claims by staking from November 2004 to May 2010 and covers 8593 hectares. In 2005, Serengeti Resources completed 12.4 kilometres of IP and ground magnetics surveying.
In 2006, Serengeti drilled 212.8 metres in three BQ diamond-drill holes. The drillholes tested induced polarization (IP) geophysical anomalies previously found. The three holes drilled on the property intersected a mafic dominated volcanic and intrusive sequence with local monzonite dikes. Drillhole T-06-02 cut a sequence of highly magnetic andesites, pegmatoidal monzo-gabbro and gabbros. Disseminated pyrite, trace chalcopyrite, and locally abundant (to 20 per cent) magnetite is present in the gabbro and likely explains the IP chargeability anomaly tested. Moderately anomalous copper and gold values were present particularly in the gabbro. A 2.1 metre drill interval assayed 0.26 per cent copper and 0.12 gram per tonne gold (Assessment Report 29410).
In 2011, the goal of Serengeti's exploration program was to complete geochemical, geological, and geophysical surveys to test for glacial-till covered copper-gold porphyry targets on the property. Linecutting (26.5 kilometres) was completed for an IP geophysical survey, geological reconnaissance was performed, and 855 Ah soil samples were collected. Also in 2011, Serengeti Resources released the results from a drill program financed by Freeport-McMoRan of Canada Limited on the Tchentlo and Choo (093N 096, 131, 227) properties. Highlights of the program include the intersection of structurally controlled mineralization in one hole (T-12-05) at Tchentlo grading 0.73 per cent copper, 0.81 gram per tonne gold, 8.4 grams per tonne silver, and 0.05 per cent molybdenum over 3.2 metres (Press Release - Serengeti Resources Inc., August 29, 2012).
