The GD (Pup and Meatball) occurrence is located at an approximately elevation of 1700 metres on a ridge south of the junction of Coppery and Dewar creeks.

The area is primarily underlain by siltstone, argillite and quartzite of the Creston Formation, while dolomitic carbonate rocks of the Kitchener Formation, both of the Middle Proterozoic Purcell Supergroup, outcrop to the east and west. Gabbro sills and dikes intrude the sediments.

Locally, two areas of mineralization (Pup and Meatball) have been identified in quartzites of the Creston Formation.

At the Pup zone, sphalerite, galena and chalcopyrite mineralization occur as fracture-fillings with in a quartzite. In 1997, a grab sample (TTGD97R-13) assayed 1.07 per cent zinc, 0.095 per cent lead and 0.045 per cent copper (Assessment Report 25392).

At the Meatball zone, located 150 metres east of the Pup zone, subcrop and boulders expose disseminated and vein stock works of galena with in a quartzite. In 1997, a sample (TTGD97R-06) assayed 72.0 grams per tonne silver and 6.84 per cent lead over 1.0 metre (Assessment Report 25392).

In 1986, Agincourt Explorations completed a program of rock sampling, geological mapping and underground surveys on the area.

In 1996 and 1997, programs of rock, silt and soil sampling were completed on the area as the GD claims.

In 2006, Eagle Plains Resources completed a 154.3 line-kilometre airborne geophysical survey on the area as the K9 property.

In 2009, a further 479.1 line-kilometre airborne geophysical survey was completed.

In 2011, Bluefire Mining Corp. conducted 364.2 line-kilometres of geophysical surveys over the property containing the occurrence.

In 2013, a program of geological mapping and rock, silt and soil sampling was completed.
