The Ed (Condor) occurrence is located at an elevation of approximately 1080 metres on a north-trending ridge separating the east and west arms of Lead Creek.

Regionally, the area is underlain by fine clastic sediments of the Ordovician Active Formation, sediments and carbonate rocks of the Middle Cambrian Nelway Formation, undivided sedimentary rocks of the Cambrian Laib Formation and quartz arenite sedimentary rocks of the Neoproterozoic to Lower Cambrian Hamill Group. To the north these have been intruded by granodioritic rocks of the Cretaceous Anstey pluton and small stocks of syenitic to monzonitic intrusive rocks of the Eocene Coryell Plutonic Suite.

Locally a shaft, an adit and surface trenches expose a mineralized northwest-trending shear zone in dolomite or recrystallized and dolomitized limestone of the Nelway Formation. Mineralization is comprised of coarse-grained, irregularly distributed galena in wavy veinlets and lenses or masses, and sphalerite occurs as blebs, disseminations, replacement veinlets and narrow rims on dolomite fragments. The shear zone is up to 0.7 metre wide and strikes 315 degrees with a vertical to steep southwest dip.

In 1990, a chip sample (LR-3) from a trench located near the former adit and shaft yielded 9.99 per cent zinc, 2.71 per cent lead, 0.11 per cent cadmium and 5.6 grams per tonne silver over 0.50 metre, whereas a chip sample (LR-2) from the shaft assayed 8.85 per cent zinc and 2.52 per cent lead over 0.7 metre (Assessment Report 20376).

In 1991, a chip sample (5963) from the shaft assayed 20.70 per cent lead, 6.24 per cent zinc and 15.0 grams per tonne silver over 0.7 metre (Assessment Report 21705).

Another zone of mineralization, referred to as the Yellow Zinc zone, is located approximately 150 metres west of the adit and shaft. This zone comprises a siliceous dolomite or recrystallized and dolomitized limestone of the Nelway Formation hosting disseminated sphalerite mineralization with bands, up to 1 metre wide, of semi-massive to massive sphalerite. The mineralized layers conform to the northeast trend and steep easterly dip of local stratigraphy and have been exposed for greater than 20 metres by hand trenching. No areas of shearing or breccia are reported from this zone.

In 1991, chip sampling (PR-8 and 5965) yielded from 29.38 per cent zinc over 1.5 metres to 12.82 per cent zinc over 4.0 metres, whereas grab samples (PR-3) yielded up to 37.03 per cent zinc and 0.09 per cent cadmium (Assessment Report 21705).

In 1993, diamond drilling yielded intercepts of up to 0.307 per cent lead over 0.3 metre in hole LB93-8 (Assessment Report 23397).

In 1953, 2 tonnes of ore were shipped, from which 156 grams of silver, 1069 kilograms of lead and 20 kilograms of zinc were recovered. In 1970, a further 255 tonnes were shipped, yielding 124 grams of gold, 1306 grams of silver, 577 kilograms of lead and 764 kilograms of zinc.

In 1952, International Lead and Zinc Mines Ltd. constructed a rough road to the ‘old prospects’ and a program of bulldozer stripping was undertaken with minor production of hand cobbed high-grade galena being mined from surface the following year. In 1953, a 27-metre long adit was driven below the trenched area and a 3-metre deep shaft was constructed. In 1970, further production occurred.

In 1990, Worthington Resources prospected and soil sampled the area as the Libby 1 claim. This work indicated that the adit had not been advanced far enough to intersect the mineralized shear identified by trenching at the surface. In 1991, Timmax Resources Corp. completed a program of rock, silt and soil sampling; geological mapping and minor trenching. In 1993, Consolidated Ram Rod Gold Corp. completed a 12.8 line-kilometre induced polarization survey and eight diamond drill holes, totalling 832.7 metres, on the area.

In 2012, a program of prospecting and geological mapping was completed. In 2019, Guinet Management Inc. completed a program of geological mapping.
