The Pam occurrence is located 2.5 kilometres south of Nadina Lake.

The occurrence is centred over a small granodiorite stock which intrudes Lower Cretaceous Skeena Group volcanic flows and tuffs. The stock and adjacent volcanics are extensively pyritized and altered. The alteration is concentrically zoned with a central potassic core grading outward into a middle phyllic zone and an outer propylitic zone.

The phyllic zone has a diameter of about 1.2 kilometres and characteristically contains 2-10 per cent pyrite as fracture coatings, veins and disseminations within a grey to white quartz-sericite-clay matrix. The extent of the potassic zone is uncertain; a few outcrops and drill holes along what is inferred to be the southern and western edges of the zone show secondary biotite and K-spar with a moderate to strong quartz-sericite overprint. The main part of the potassic zone is thought to occupy the central part of the phyllic alteration zone and underlie a core measuring approximately 800 by 500 metres.

In 1991, several drill holes intersected significant copper-molybdenum mineralization with the best hole averaging 0.11 per cent copper and 0.01 per cent molybdenum over 73 metres (Assessment Report 21969). Although the mineralization intersected to date is low grade, there is a definite increase in grade toward the potassic core.

In 1999, a bedrock sample (64899) returned values of 827 parts per billion gold, 350 parts per million copper and 319 parts per million arsenic (Assessment Report 26254).

In 2012, a 16 metre trench chip sample, located 50 metres north of the main showing, yielded 0.548 per cent copper (Assessment Report 33921).

In the 1960s and early 1970s, numerous companies carried out large scale, helicopter-supported, regional prospecting and stream sediment sampling programs in the area. In 1972 and 1973, Hudson Bay Oil and Gas Limited completed an airborne magnetic survey including the area presently covered by the Sylvia and Pam claims. These surveys were followed up with preliminary reconnaissance mapping and geochemical sampling. In 1974 and 1975, HBOG carried out follow-up geological, geochemical and geophysical surveys on the Slide, Sylvia and Pam claims and drilled 56 percussion drill holes, totalling 2944.5 metres. In 1991, the area was staked by Kingsvale Resources Limited who conducted a preliminary geological and geochemical sampling program. In 1999, a limited soil and rock sampling program was performed on the Pam claims. In 2011 and 2012, limited prospecting, geochemical sampling (including humus sampling) and mapping programs were completed by KDG Exploration Services. This work identified the Pam South occurrence. In 2013, KDG collected 24 rock samples and 78 humus samples, the latter collected from four lines across the property. Humus samples were collected at 100 metre intervals on lines spaced generally between 350 meters and 1000 metres which spanned the areas of Pam and Pam South (093E 132) occurrences. Several rock samples were collected in the Pam alteration zone.
