The Rag 73 (Western Magnetite zone) occurrence is located east of Ferguson Creek and approximately 250 metres south of the southern end of Norman Lake.

The area is underlain by Upper Triassic Nicola Group volcanic rocks consisting mainly of andesitic volcanic flows and fragments intruded by a Triassic composite diorite-monzonite intrusion (Durand Lake stock). The intrusion is widely mineralized with chalcopyrite and occurs with variable amounts of magnetite and pyrite. There are limited enriched zones of chalcopyrite, pyrite, magnetite and some pyrrhotite in volcanics near the intrusive contact.

Locally, as defined by diamond drilling by Cominco in 1975, fine- grained andesite flows containing brecciated sections mineralized with abundant magnetite occurring between the fragments with associated amounts of chalcopyrite and pyrite. Copper content is highly variable with the best grades occurring in the breccias. Chalcopyrite also occurs as disseminations and fracture-fillings outside the breccias. Minor epidote, calcite and potassium feldspar veinlets are associated with the sulphide mineralization in the breccias. Some sections of the andesite flows are also pervasively chlorite altered.

In 1970, percussion drilling (hole R-70-1) of the western end of the Durrand stock-margin is reported to have yielded up to 0.18 per cent copper over 60.6 metres, including 0.35 per cent copper over the last 9 metres of the hole (Assessment Report 25124).

In 1997, diamond drill hole R97-9 yielded intercepts up to 0.26 per cent copper and 0.13 gram per tonne gold over 66.44 metres, including 0.41 per cent copper over 27.52 metres, while a later hole (R97-21) intersected a lapilli tuff where a 2-metre section assayed 5.83 grams per tonne gold between 116 and 118 metres (Assessment Report 25124).

During 1965 through 1967, Noranda Exploration completed programs of geological mapping, soil sampling and minor trenching on the area as the G.B. claims. Cominco Ltd. staked the original Rag claims in 1969 to cover the northern and western part of an aeromagnetic anomaly associated with a Triassic composite diorite-monzonite intrusion (Durand Lake stock). Extensive geological and geophysical programs were conducted during 1969 through 1972 and outlined disseminated sulphide zones (5 to 8 per cent pyrite) along the west-southwest and east-northeast flanks of the intrusion. These peripheral areas have been covered by induced polarization and magnetic surveys and a limited amount of percussion drilling. In 1970, induced polarization and ground magnetometer surveys and line cutting totalling 29 line- kilometres were run over the Rag group of claims on behalf of Cominco Ltd. In 1972, line cutting and an induced polarization survey totalling 26 line- kilometres were completed over the Rag claim group on behalf of Cominco Ltd. In 1975, Cominco Ltd. drilled two diamond -drill holes, totalling 272 metres, on the Rag 73 claim. In 1979, Cominco Ltd. conducted 15 kilometres of line cutting and an induced polarization survey on the Rag property. In 1988, Cominco Ltd. conducted soil sampling (619 samples) over the Rag claims. In 1989, Teck Corporation entered into a joint venture agreement with Cominco Ltd. covering Teck- and Cominco-owned claims in the Greenstone Mountain area. During the spring and summer of 1990, Teck conducted soil sampling (500 samples), magnetometer (38 kilometres) and VLF-EM (38 kilometres) surveys over previously untested portions of the Rag claims. Also, in 1990 on behalf of Teck Corporation, a nine-hole percussion drilling program, totalling 716 metres, tested two gold- copper soil geochemical anomalies on the Rag claims in addition to 38 line- kilometres of VLF-EM and ground magnetometer surveys and 500 soil samples. In 1992, Cominco completed a 29.5 line-kilometre induced polarization survey. In 1989, D.L. Cooke and R.U. Bruaset began assembling ground (Rabbit claims) in the Dominic and Durand lakes area and this continued, with some interruptions, until 1996. The Rabbit claims cover the Bruce (MINFILE 092INE114), Rag 73 and Rag (MINFILE 092INE045) occurrences. Bruaset and Cooke carried out systematic geological mapping and a soil geochemical survey (135 samples) directed at gold beginning in 1990 in the area of the Rag 73 and Rabbit (MINFILE 092INE147) occurrences. In 1993, a compilation map was completed based on the analysis for gold of 2900 soil samples form the Dairy to Dominic lakes area. This compilation, which covered most of the area of current Rabbit claims, suggested high gold potential. In 1995, ProAm Explorations Corporation extended the 1990 gold soil anomaly, and in the same year, the entire ProAm Rabbit group of claims was surveyed by enzyme leach selective extraction. In 1996, a program of rock and soil sampling and a 7.3 line-kilometre induced polarization survey were completed. In 1997 and 1998, ProAm Explorations Corporation completed nine trenches totalling 40 metres and took 80 outer bark samples for biogeochemistry testing in the vicinity of the original Bruce occurrence. The trenching confirmed the presence of copper mineralization and yielded elevated gold values. Also, in 1997 ProAm conducted a diamond drilling program over the original Rag 73 occurrence and discovered the Rabbit occurrence. A total of 21 holes, totalling 3338 metres, were drilled and 1398 samples were collected and analyzed. In 2003 and 2004, Auterra Ventures conducted a program of trenching, geochemical sampling and ground geophysical surveys on the area as the Rabbit North property. In 2010, a program of rock and soil sampling and geological mapping was completed.

During 2013 through 2015, Tower Resources completed programs of rock sampling, geological mapping and airborne and ground geophysical surveys on the area as the Rabbit North property.
