The Swede occurrence is on the western side of Swede Peninsula and east side of Anna Inlet in Klunkwoi Bay, Moresby Island. The primary past workings are located between sea level and 457 metres elevation, whereas other workings and drillholes are reported on the eastern side of the peninsula, northwest of the Salmon River mouth.
The area is underlain mainly by Upper Triassic Karmutsen Formation (Vancouver Group) volcanics consisting of andesitic agglomerate, pillow lavas, ignimbrite, amygdaloidal basalt and minor sandstone and limestone. The volcanics are overlain by massive grey limestone, black limestone and limy argillites of the Triassic to Jurassic Kunga Group. The rocks are cut by dacite, andesite and diorite dikes related to the Eocene-Oligocene Kano Plutonic Suite.
The peninsula is bounded by two north-trending major faults, thought to be block faults. Weak shearing, brecciation and silicification have developed between the two faults.
Locally, amygdaloidal basalts host fine disseminations, blebs, veinlets and stringers of chalcopyrite and rare bornite with minor amounts of pyrite and pyrrhotite. The sulphides show preferential concentration with areas of chloritized and epidotized amygdules. Quartz-calcite stringers and veinlets are also reported. The mineralization has been traced for at least 90 metres along the Anna Inlet side of the peninsula and for at least 150 metres on the Salmon Creek side. Some samples from the "Bornite" adit assayed small values in silver, gold, platinum and trace palladium and gallium (Property File - Selnes, W.E. [1970-12-02]: Prospectus - Ana Lake Mining Ltd.).
In 1916, drilling is reported to have yielded 0.75 per cent copper over 9.45 metres in hole no.1 and 0.66 per cent copper over 20.7 metres in hole no. 2, including 1.05 per cent copper over 8.25 metres, whereas another section of hole no. 2 assayed 2.1 per cent copper, 20.5 grams per tonne silver and 6.8 grams per tonne gold over 1.05 metres (Property File - Ana Lake Mining Ltd. [1988-12-06]: Prospectus - Ana Lake Mining Ltd.). The entirety of holes 1 and 2 averaged 0.12 per cent copper over 49.8 metres and 0.20 per cent copper over 115.8 metres, respectively (Property File - Ana Lake Mining Ltd. [1970-12-06]: Prospectus - Ana Lake Mining Ltd.). These holes were located on the Salmon Creek side of the peninsula.
In 1956, an opencut above the upper tunnel is reported to have yielded approximately 0.5 per cent copper over a length of 7.5 metres (Property File - E. Livingston [1956-01-01]: Geological Report on the Swede Group).
In 1967, the three adits were sampled, yielding values from 0.35 to 2.5 per cent copper and 6.86 grams to 20.57 grams per tonne silver, including up to 0.35 per cent copper and 8.6 grams per tonne silver over 9 metres from the south wall of the no.1 adit; 1.70 per cent copper and 20.5 grams per tonne silver over 4.5 metres from the south wall of the no.2 adit and 2.05 per cent copper across 3.0 metres from the no.3 adit (Property File - Selnes, W.E. [1970-12-02]: Prospectus - Ana Lake Mining Ltd.).
In 1970, bulk sampling tested two zones. The first zone, covering an area 120 metres wide by 240 metres in length on the Anna Inlet side of the peninsula, yielded an average of 0.30 per cent copper, whereas the second zone, located on the Salmon Creek side of the peninsula, yielded 0.66 per cent copper over an area of 180 by 180 metres (Property File - Ana Lake Mining Ltd. [1970-06-22]: Report - Brandy Mineral Claims).
The Swede group, consisting of eight claims, was staked in January 1907 by Messrs. Larsen, Pearson, and Rogers. The adjoining Last Chance group (MINFILE 103B 003), consisting of six claims, was staked late in 1907 by Messrs. Wintermite, McEachern and Jones. A few opencuts were developed on the properties. In 1908, the property was bonded to J. Wulffsohn, who by 1910 had carried out development work in three adits. The main adit, 24 metres above sea level, was driven for 52 metres. Another adit, 24 metres to the east and on the same level as the main adit, is a 10-metre long drift. A third adit, at an elevation of 137 metres, was driven for 17 metres. In 1916, The Granby Mining Company Limited carried out 607 metres of diamond drilling in nine holes.
In 1951, Granby made a further reconnaissance examination of the property. In 1956, New Jersey Zinc Explorations Company (Canada) Limited optioned the property and completed a program of geological mapping, sampling, and three diamond drill holes, totalling 99 metres. Queen Charlotte Resources Ltd. acquired the property during 1961, and carried out geological and geophysical surveys. In 1967, Cosmic-Lode Mines Ltd. acquired the property under option from Fleetwood Resources Ltd. Work on the property, then known as the "D" claims, included five trenches, totalling 305 metres, and eleven diamond drill holes, totalling 305 metres. In the fall of 1968, the area was restaked as the Brandy group and later transferred to Ana Lake Mining Ltd. In 1969, the company conducted a program of bulk sampling of the mineral zones exposed in the adits and trenches, deepened old trenches and trenched new areas. Preliminary geological mapping and topographical surveys were carried out. X-ray diamond drilling totalling 921 metres was done to obtain geological and structural information on the mineralized zones. An airborne magnetometer survey was completed in August 1969.
In 1976, Rio Tinto completed a program of rock and silt sampling, geological mapping and a ground magnetic survey on the area as the Merry K property. In 1983, J.S. Christie and G.G. Richards sampled and mapped the Eagle, Lock and Raven claims. Diamond International Industries Inc. sampled in 1985 and drilled three holes, totalling 261.5 metres in 1988.
