The Gold Bug (Lot 890) is located west of Boundary Creek, near the north boundary of the community of Greenwood.

The area is underlain by chert, limestone, siliceous argillite and siliclastic rocks of the Devonian to Permian Knob Hill Group, which have been intruded by granite and granodiorite of the Cretaceous Greenwood stock (Anstey pluton) and Miocene pulaskite porphyry. Undivided sedimentary rocks of the Triassic Brooklyn Formation outcrop to the west.

Mineralization is described as chalcopyrite, pyrite, pyrrhotite, and magnetite or hematite occurring along fractures and interstitially between grains in a skarn zone formed at the contact of the limestone and granitic rocks. Other reports describe exploration by adits and opencuts of a 15-centimetre wide mineralized vein extending from the D.A. to Gold Bug Crown grants.

The Gold Bug tunnel and shaft or stope, located near the border of the D.A. and Gold Bug Crown grants at an elevation of approximately 842 metres, expose a narrow, high-grade quartz vein hosting galena and zincblende (sphalerite?). The vein strikes south 75 degrees west and dips 40 degrees south. The vein is reported to be cut by a dike to the southwest.

The D.A. tunnel, located approximately 450 metres to the southwest, near the southwest corner of the D.A. claim and at an elevation of 938 metres, was driven for 142.2 metres along a strike of north 35 degrees west, with drifts following a pyritized shear plane in the granodiorite in both directions for approximately 4.5 metres and a raise driven for approximately 15 metres. Volcanic tuffs and breccia are reported near the face of the tunnel. A 5.4-metre deep shaft is located approximately 12 metres southwest of the tunnel and is reported to have exposed a high-grade, 0.6 to 0.9-metre wide, pyrite-bearing quartz vein. A short tunnel and opencut are located approximately 90 metres beyond the end of the main tunnel and expose a narrow, 0.1-metre wide, mineralized quartz vein, striking south 57 degrees west and dipping 54 degrees southeast, in highly altered graphitic schist and argillite. A 248.6-kilogram shipment of sorted ore from the opencut is reported to have averaged 9.9 grams per tonne gold, 4631 grams per tonne silver, 7.2 per cent lead and 5.8 per cent zinc (Property File - B.W.W. McDougall [1926-10-20]: The D.A. Group Of Mineral Claims and the Dynamo Mineral Claim - Deadwood and Skylark Camps - Boundary District).

The Sudbury shaft, located approximately 1 kilometre to the northwest at an elevation of 965 metres, was sunk for 15 metres, with minor drifting being performed at the bottom shaft. Mineralization is reported to consist of sulphide pods or bunches, primarily chalcopyrite, in limestone at its contact with volcanic tuffs and breccias. The mineralized zone strikes south 72 degrees west and dips 47 degrees northwest. In 1926, a sample (no. 10) taken across a pillar near the end of the shaft assayed 71.8 grams per tonne silver and 1.4 per cent copper over 2.25 metres, whereas a sample (no. 11) of sorted ore yielded 42.4 grams per tonne gold, 20.5 grams per tonne silver and 18.5 per cent copper (Property File - B.W.W. McDougall [1926-10-20]: The D.A. Group Of Mineral Claims and the Dynamo Mineral Claim - Deadwood and Skylark Camps - Boundary District).

Intermittent production from 1901 to 1954 totalled 89 tonnes, resulting in 68.12 kilograms of silver, 1.34 kilograms of gold, 233 kilograms of copper, 431 kilograms of zinc and 539 kilograms of lead. Of this, 2.7 tonnes grading 1573 grams per tonne silver with 22.9 grams per tonne gold came from the Gold Pick Fraction (L.1092), 41.7 tonnes grading 564.3 grams per tonne silver with 19.5 grams per tonne gold from the Gold Bug (L.890) Crown grant and 39.0 tonnes grading 735.3 grams per tonne silver with 10.3 grams per tonne gold from the D.A. (L.824) Crown grant (Property File - Rocket Energy Resources Ltd. [1987-06-30]: Prospectus Report - Greenwood Claims). Approximately 27.2 tonnes of ore was reportedly produced from Sudbury claim and averaged approximately $40.00 per ton (Property File - B.W.W. McDougall [1926-10-20]: The D.A. Group Of Mineral Claims and the Dynamo Mineral Claim - Deadwood and Skylark Camps - Boundary District).

The area has been explored since the late 1890s with production starting in 1901. Development work has included at least three adits on the Gold Bug (L.890) Crown grant; two opencuts, two shafts and a tunnel on the D.A. (L.824) Crown grant; a shaft on the Sudbury claim and a shaft on the Gold Pick Fraction (L.1092).

During 1983 through 1987, the area was examined by Rocket Energy Resources Ltd.

During 2008 through 2012, Grizzly Discoveries Inc. completed programs of rock and soil sampling, geological mapping, ground geophysical surveys and diamond drilling on the area as the Motherlode portion of the Greenwood property. In 2010, a sample (10JHP130) of mineralized skarn and limestone from a shaft assayed 16.6 grams per tonne gold, 2110 grams per tonne silver, 0.216 per cent copper, 1.4 per cent lead and 0.298 per cent zinc (Dufresne, M. (2013-11-25): Technical Report for the Greenwood Gold Project).
