The Allin occurrence is located 19 kilometres north of Francois Lake and 4.4 kilometres east of the Equity Silver deposit. The area is underlain by the Eocene Goosly Lake Formation (Francois Lake Group).
Locally, Allin creek has been defined as a regional boundary with Buck Creek formations of andesite-basalt composition occurring to the east and Goosly Lake Formation trachyandesite to the west. A triangulated wedge of Equity sequence rock is indicated in the southwest limits of the claims.
Government mapping in 1990 (Church and Barakso) and Alldrick and Lin (2007) show the Allin area to be underlain by andesites and trachy-andesite flow breccias belonging to the basal part of the Paleocene Goosly Lake Volcanics. However, mapping along Allin Creek by Ray (Assessment Report 34409) also shows the presence of a small body of quartz microdiorite and some highly altered gossanous volcanics that were probably dacitic.
Outcrops on the Akin property are very limited. Mapping, prospecting and drilling, both past and present, indicate much of the claims are covered by a thick compact blanket basal till with depths ranging from 6.5 metres to as much as 85.35 metres. The only known areas of outcrops are along a north-south–trending ridge located east of Allin Creek, where numerous outcrops of basalt occur, and along the east-flowing section of Allin Creek between the Allin 1 and 2 claims, where outcrops consist of altered volcanics and unaltered intrusives.
The Allin property has undergone numerous phases of exploration since the 1970s, including prospecting, mapping, geochemical sampling and geophysical surveying. During this time, a number of targets including low-order coincident copper-silver soil anomalies and multiple induced polarization anomalies have been located and drill tested with largely inconclusive results.
The property lies on the eastern boundary of the Equity Silver Mine property (093L 001). Drilling in 1987, within an area of coincident geochemical and geophysical anomalies, intersected moderately to strongly altered (quartz-sericite-pyrite and chlorite-calcite-pyrite) volcanic rocks with up to 15 per cent disseminated and fracture-controlled sulphides. The volcanic rocks consist of interlayered andesite, dacite and latite flows, tuffs and lapilli tuffs cut by narrow unaltered dacite and andesite dikes. The sulphides comprise pyrite and pyrrhotite with minor to trace sphalerite, chalcopyrite, arsenopyrite, galena, molybdenite and tetrahedrite.
WORK HISTORY
The Dev claims were first staked in 1968 by Silver Standard Mines and Dorita Silver Mines joint venture following the discovery of the Equity Sliver copper deposit by Kennco Exploration Ltd in 1967. Exploration by Sliver Standard and Dorita consisted of line cutting soil geochemical sampling and geophysical surveys. Frequency domain IP and resistivity surveys were carried out and several metal factor IP anomalies were interpreted. Several short diamond drill holes were completed but the results were not publicized.
In 1964 the DEV claims were staked by Summit Oil Ltd over the southern half of the existing property Delbrook Mines Ltd explored the property in 1970. Soil geochemical sampling and magnetic surveys were carried out by both companies Al though low order silver and copper anomalies were found no further exploration was carried out and the ground was allowed to lapse
In 1986, the existing DEV 1 to 4 and GO 1 to 3 claims were staked by Kengold Mines Ltd and subsequently optioned to Normine Resources Ltd. Westvlew Resources Ltd earned a 49 per cent interest in the property in 1986 and 1987. Exploration in 1986 consisted of grid establishment, limited soil geochemical sampling and IP and magnetic surveys were conducted. Coincident copper silver soil geochemical and IP anomalies were defined and followed up during the 1987 by diamond drilling totalling 652.6 metres in four holes. The GO 4-6 claims were also staked during the 1987 season
In 1989, Bema Gold conducted a 1.4 kilometre IP survey on the Dev 3 claim (Assessment Report 19409).
Prospecting in 1992 by Gerald Klein produced mineralized float boulders that contained similar copper/silver grades to those found at the then-shutting-down Equity deposit located some 5 kilometres to the northwest. Based on this information, Equity Mines Ltd. optioned the Allin property from Gerald Klein and proceeded to complete seven drillholes on several induced polarization targets and a coincident copper-silver soil anomaly. Results from this phase of drilling also failed to explain the sources of the anomalies (Assessment Report 23132).
In 1996, Hudson Bay Exploration and Development Co. Ltd. optioned the Allin l to 3 claims and proceeded to stake the Allin 4 to 8 claims for G. Klein. A review of previous work suggested that a thick layer of overburden covered much of the property and that this overburden might cover blind deposits that are not amenable to conventional geochemical exploration techniques. Due to this possibility and some question regarding the ice direction of the last glaciation in the area, a geochemical sampling program in the summer of 1996 was conducted using enzyme leach techniques, which are said to penetrate thick overburden. From this work, 10 enzyme leach anomalies and one induced polarization target were selected for drilling during the 1997 exploration season (Assessment Report 25028).
In 1997, diamond drill program was conducted by Hudson Bay Exploration & Development Co. Ltd. on the Allin Creek property (Assessment Report 25381). The program consisted of five BQ and six NQ sized diamond drill holes totaling 2177 meters. These holes tested IP and enzyme leach anomalies delineated and compiled during the 1996 exploration program. The results of the 1997 drill program failed to intersect any significant base and/or precious metal mineralization. The source of the mineralized float boulders remains unknown.
In early 2013, Finlay Minerals Ltd acquired the Allin claims, located immediately east of Finlay's Silver Hope property One day of prospecting and sampling was conducted on the recently acquired Allin claims (Assessment Report 34409) Very impressive alteration zones along an east flowing stream did not yield any anomalous metal concentrations. The source of VMS style float discovered in 1992 remains a mystery. Recent glacial studies suggest that ice may have moved from east to west, counter to what most exploration companies had assumed. In 2012, aeromagnetic surveying completed on behalf of Finlay Mineral had some coverage in the Allin area.
