Exploration History

1916: Early exploration at the start of the initial gold rush to the Tashota area, following the completion of the national transcontinental railway (i.e., the CNR mainline) in 1913. 1917: a 15 m, inclined shaft was sunk on a quartz vein system at what was then known as the “Hull Claims”. 1928: Coniagas Mines Limited drilled 2 DDH totalling 306 m, near the south shaft area. Discouraging results forced the company to drop the property. Kipper Tashota Gold Mines Limited was formed to manage the property. A second, 10.5 m vertical shaft was sunk on what was thought to be the southern extension of the north shaft vein system (located east of Emily Creek road). 1936: Kipper Tashota Gold Mines Limited was chartered in Ontario and renamed Lincoln Gold Mines Limited. Extensive sampling of numerous hand-dug trenches and test pits was conducted into the late 1930s. 1973: The ground was restaked by J.F.M. Croteau. 1975: Derry, Michener and Booth completed an 11-hole Winkie diamond-drilling program, totalling 219 m, detailed geological mapping, and ground magnetometer surveys for Westburne-G.P. Drilling Ltd. Seven holes were completed near the north shaft and the remaining 4 holes were located near the south shaft (holes 75-1, 75-2, 75-10, and 75-11). 1998: NWT Copper Mines Ltd. acquired the property by staking late in 1998. 1999: NWT Copper Mines Ltd. completed an extensive prospecting, surface stripping and sampling program at the north and south shaft zones during the 1999 field season. 2000: the Lincoln property was optioned to International Taurus Resources Inc.; a joint venture for the project was arranged with International Kodiak Resources Inc. Field work in 2000 consisted of mechanical stripping, detailed mapping and sampling. Seventy-five trenches and stripped zones, covering a 350 by 800 m area, were exposed during the program. 2001: The two companies completed an 8.8 km long IP survey covering the main zones, which subsequently uncovered 4 high-priority anomalies. 2003: Kodiak Exploration Limited completed a 13-hole diamond-drilling program across the south, central and northern portions of the main zone.

Geology Comments

Oct 30, 2018 (Robert Cundari) - The Lincoln property is situated within mafic metavolcanic rocks of the north-central portion of the Onaman–Tashota greenstone belt, which is part of the eastern Marmion domain of the Wabigoon Subprovince. The immediate vicinity is dominated by 3 coeval, late-tectonic felsic plutons, namely the Robinson, Deeds and Gzowski plutons. Stott, Straub and Fortin (1998) indicated that each of these intrusive bodies has produced a strain aureole in the surrounding metavolcanic rocks. The Lincoln occurrence is situated within the strain aureole of the Gzowski pluton (2698.3±1.3 Ma), which is located only 3 km east of the property. Iron carbonate and sulphide enrichment is typical of these high-strain zones and is most prominently displayed at NWT Copper Mines Ltd.’s North zone. Feldspar porphyry dikes, potentially related to the nearby Gzowski pluton, host the most significant and consistent gold mineralization displayed at the Lincoln South zone (White et al., 2013).

Mineralization Comments

Oct 30, 2018 (Robert Cundari) - Drill-core logs from the Derry, Michener and Booth’s 1975 drilling program at the Lincoln North and South zone shaft areas described the alteration (Chance 1975). Highly carbonatized and silicified sections, containing up to 15% disseminated pyrite (with an average of 3 to 5%), occur in both the chlorite-rich mafic metavolcanic rocks and the feldspar porphyry dykes. These altered sections correlated with the best gold assays (up to 28.0 g/t Au). Both the shearing and foliation within the metavolcanic rocks and the feldspar- and quartz-feldspar porphyry dikes generally strike north with steep, easterly dips. A January 11, 2002, International Kodiak Resources Inc.’s website described the local geology and mineralization of the Lincoln gold property: Gold, copper, sulphides, arsenopyrite and pyrite occur in quartz vein zones up to 20 m wide cutting both feldspar porphyry and surrounding metamorphic rocks. Recent sampling has confirmed previous high-grade assays over 1 to 3 m widths. Also of interest is the occurrence of significant gold values in the feldspar porphyry and other host rocks. This feature, the importance of which has not been previously recognized, shows potential for a large bulk-tonnage gold deposit in addition to the prospect of near-term high-grade gold production from the veins (Thunder Bay North Resident Geologist’s office files). Samples collected over the years have returned erratic values ranging from 2.2 up to 67.2 gpt Au. A sample collected by RGP staff in the North Shaft area in 2012 returned an assay of 7.03 gpt Au (White et al., 2013).

Notes: Resident Geologist Program staff visited both the North and South zones at the Lincoln property in 1999 and again during the 2012 field season. The North Zone stripped area exposes a north-trending (i.e., striking 340�), moderately sheared, chlorite-rich lapilli tuff containing 2 to 5% pyrite as seams and disseminated grains. Highly deformed, but conformable, quartz veins and veinlets, and rusty iron-carbonate alteration are prominent across the outcrop. Gold values from grab and channel samples are erratic, but exceed 30 g/t Au at one location. Within the north shaft (UTM 456555E 5565494N, Zone 16), along the Emily Creek road, visible gold associated with 2 to 10% pyrite and some tourmaline was noted. In the South zone, stripping by NWT Copper Mines Ltd. in 1999 exposed what was termed the �quartz dome�, which is a prominent bedrock knob covered by a series of flat-lying quartz veins. Below this thin veneer of quartz, the outcrop consists of strongly sheared mafic tuffs and pillowed basalts, intruded by a second generation of quartz (striking 135 to 140�) and, more importantly, a series of feldspar porphyry dikes from 2 to 3 m wide. Alteration includes silicification, chlorite and tourmaline. Approximately 60 m south of this stripped area, 2 zones, known as the �Skinny� and �Fat Fox� occurrences, were uncovered by the company by hand stripping. (The south shaft lies between the �quartz dome� and these occurrences.) Here, north-trending quartz-feldspar porphyry dikes have intruded silicified mafic metavolcanic host rocks. On average, these dikes contain 2 to 5% disseminated pyrite and up to 1% chalcopyrite.
