The Lydy occurrence is located east of Baker Creek and approximately 2.5 kilometres west of Burdett Peak.

The area is predominantly underlain by a north trending sequence of argillite and quartzite units of the Middle Proterozoic Mount Nelson Formation (Purcell Supergroup). This assemblage abuts the older conglomerate unit of the Upper Proterozoic Toby Formation (Windermere Supergroup) to the west and sedimentary rocks of the Dutch Creek Formation (Purcell Supergroup) to the east.

Locally, as defined by diamond drilling, quartzitic carbonates and siliclastic rocks host small, less than 5 centimetre wide, quartz-carbonate breccia veins with massive to disseminated pyrite, minor galena and possible wolframite.

In 2005, diamond drilling yielded up to 13.7 grams per tonne silver over 20 centimetres (sample 05-21 #23), 0.895 per cent zinc over 1.22 metres (sample 05-21 #24) and 0.665 per cent lead with 3.2 grams per tonne silver over 1.09 metres (sample 05-25 #38) from drill hole 05-01, while drill hole 05-04 yielded up to 33.3 grams per tonne silver over 12 centimetres (Sample 05-04-72; Assessment Report 27947).

During 1978 through 1984, Cominco completed programs of soil and silt sampling and geological mapping on the area as the Baker claims. This work centered on the Baker (MINFILE 082FNE004) molybdenite occurrence to the north.

During 2005 through 2007, Mountain Star Resources completed programs of soil sampling, diamond drilling, totalling 1165.8 metres in six holes, and a 110.0 line-kilometre airborne geophysical survey on the area as the Lydy claims.
