The Heath #3 showing is situated between Mount Nation and the west end of Tchentlo Lake, approximately 57 kilometres southeast of Takla Landing. Copper mineralization was originally discovered to the northwest at the Heath #1 prospect (093N 072) in 1968, as a result of anomalies outlined by a regional geochemistry survey.

The area is underlain by mesozonal plutonic rocks assigned to the Late Triassic to Early Cretaceous Hogem Intrusive Complex which have been emplaced into volcanic rocks of the Middle Triassic–Lower Jurassic Takla Group, east of the Pinchi fault zone. Of the three phases comprising the Hogem Intrusive Complex, only rocks of the Late Triassic to Lower Jurassic Hogem granodiorite and Hogem basic suite underlie the Mount Nation area. Diorite is the most abundant rock type, hosting irregular bodies of coarse-grained clinopyroxene gabbro, pyroxenite and hornblendite and local feldspar porphyry, diabase, granodiorite and andesite porphyry dikes. Granodiorite has also been mapped to the east. These rocks are disrupted along several subordinate faults paralleling the Pinchi fault zone to the east and have undergone widespread propylitic and potassic and local carbonate alteration.

Widely distributed disseminations, stringers and fracture fillings consisting of chalcopyrite, pyrite, epidote, calcite, magnetite, hematite and bornite occur in diorite exposed in the area. A sample of one, 15-centimetre wide epidote-chalcopyrite vein exposed south of a small creek assayed 2.12 per cent copper, 761.1 grams per tonne silver and 0.86 gram per tonne gold (Assessment Report 20552, page 14).

HISTORY

Colin Campbell held claims covering the core of the Heath property since 1968 when he discovered copper mineralization during steam sediment anomaly follow-up. He excavated several hand-trenches exposing magnetite-chalcopyrite fissure veins with intensely-altered wallrock zones that were anomalous in lead, zinc, silver, gold and copper.

In the spring of 1969, Amax Exploration conducted a reconnaissance soil geochemical survey over an area near the centre of the property. The pulps were analyzed for copper and molybdenum. This survey outlined a 2,000 meter by 2,400 meter zone of anomalous Cu defined by analyses exceeding 200 ppm.

In October of 1969, the property was optioned to Senate Mining and Exploration Ltd. who carried out geological mapping and a ground magnetometer survey. It was returned to Mr. Campbell in 1972 and optioned that same year to Nation Lake Mines Ltd.

In 1973, McPhar Geophysics was contracted by Nation Lake Mines to carry out a frequency domain induced polarization survey over the Amax soil grid. Seven linear anomalies were identified and a broad anomalous zone measuring 300 meters by 600 meters was outlined. A three-hole drill program was recommended, but the option was dropped.

No exploration was done between 1973 and August of 1988 at which time Mr. Campbell tested the gold geochemical response on two small detailed soil grids in areas of known mineralization. The soil samples returned analyses ranging up to 1035 parts per billion gold, 100 parts per million silver and 32,000 parts per million copper (Assessment Report 17988).

In 1989, Teck completed 86 line kilometers of ground magnetics and VLF-EM on a 9 square kilometer grid in the centre of the property and collected 4,152 soil samples (Assessment Report 20552). Teck's 1990 program consisted of 1.6 linear kilometers of excavator trenching, 9.2 line kilometers of IP surveys, 121.92 meters of diamond drilling and collection of 2279 soil samples. In 1991, a summary field report detailed the results of an IP survey which identified several broad high chargeability anomalies. A subsequent 969 metre, 10 hole drilling program failed to intersect economically important grades and thickness of porphyry copper gold mineralization (Assessment Report 21948). It concluded that the drilling had not encountered materials of economic value and suggested a further program:

In 2001, using a government prospector grant, Mr. Campbell revisited the property and sampled the coarse grained gabbroic and pyroxene materials (Prospectors Report 2001-44). Several samples were anomalous in platinum group elements. Three X-ray holes were drilled testing areas near the previously trenched area.

In 2007, long-time owner Colin Campbell conducted a 40 sample soil survey and a 0.8 kilometer ground magnetic survey (Assessment Report 29436).
