Exploration History

1916 - Gold was first discovered on Elstone-Dunkin claim. This was followed up by tenching and diamond drilling. 1927 - Elstone-Kirkland Mines Ltd. took over the property. 1938-40 - The property was taken over by Anoki Gold Mines Limited. A surface plant was installed and a shaft was sunk to 754 feet with levels at -350, -75, -600 and -735 feet. Ore was outlined on the -350 and -475 levels. 1946 - Property was sold to Queenston Gold Mines Ltd. 1947 - Surface and underground diamod drilling. 1987-89 - Inco-Queenston joint venture. A decline was driven to the -750 foot level with connections to the old -350, -476, -600 and -735 foot levels. This was part of a $7 million exploration program that also included diamond drilling and the processing of a 30 000 ton bulk sample. 1996- Diamond drill program by Queenston-Franco-Nevada to test the continuity and extend the known reserves. 1996: Queenston purchased Inco?s interest in the mineral rights for the deposit. 1996-2001: Under the joint venture between Queenston and Franco-Nevada, 18 surface drillholes totalling 11,580 m were completed. 2002-2010: Queenston Mining carried out geophysical surveys (magnetics and IP) and completed 45 drillholes totalling 22,361 m from 2002-10.

Geology Comments

Mar 10, 2010 (D Guidon) - from Ewert 2009 The Kirkland Lake Gold Camp (KLGC) occurs in the south-western portion of the Abitibi greenstone belt of the Archean Superior Province of the Canadian Shield and the regional geological setting of the Kirkland Lake area is typical of many gold camps located within the Superior Province. The KLGC occurs on the southern limb of the regional Blake River synclinorium, the northern and southern limbs of which are truncated respectively by the Destor-Porcupine Break ("DPB") and the Cadillac-Larder Lake Break ("LLB") with its associated deformation corridor (the LLDZ). The majority of the historical gold production in the Abitibi Greenstone Belt is spatially associated with these two major regional structures (Queenston, 2001 Annual Report). In the Kirkland Lake area, the LLB is considered to be a major east-west trending thrust fault that developed along the contact zone between mafic and ultramafic rocks of the Larder Lake Group to the south and mafic volcanic rocks of the Kinojevis Group to the north. Through recent age dating and review by the Ontario Geological Survey, these rocks have recently reclassified as parts of Tisdale Group and the Blake River Group respectively. Expansion along the LLB created a graben-like basin which was filled with calc-alkaline volcanic and clastic sedimentary rocks that formed the Timiskaming Group. Later compression of this region created parallel and splay faults in both the Timiskaming and Lower Tisdale Group (Larder Lake Group) rocks, along which many of the gold deposits of the KLGC were formed. Today the LLB represents an unconformity between the Lower Tisdale Group rocks to the south and a 0.6 km to 5 km thick section of Timiskaming Group sedimentary and volcanic rocks to the north. Both the major rock groups in the area have been intruded by gabbroic and mafic-felsic intrusions, the most prominent are the Lebel Stock, Otto Stock, Murdoch Creek Stock and the Round Lake Batholith (Queenston, 2008 Annual Information Report). The Timmins-Kirkland Lake segment of the Abitibi Greenstone Belt has been divided into nine supracrustal assemblages, as described Assemblages are described in order of increasing age. Timiskaming - Contains sedimentary and alkali volcanic rocks including iron formation, such as Upper Canada and Macassa Mines. Porcupine - Comprises sedimentary and calc-alkalic volcanic rocks including iron formation. Upper Blake River - Comprised of mostly calc-alkalic volcanic rocks, such as at the Noranda Camp. Lower Blake River (Kinojevis) - Comprised of mostly tholeiitic basalts, such as at the Holt McDermott Mine. Upper Tisdale (Gauthier) - Comprised of calc-alkaline felsic to intermediate volcanics exhibiting flow and debris flow characteristics and associated volcaniclastics sediments. Lower Tisdale (Larder Lake) - Comprised of mostly komatiitic, tholeiitic and calc-alkalic volcanic rocks and iron formation, such as at the Kerr Addison Mine, McBean Mine and Anoki deposits. Kidd-Munro - Comprised of komatiitic, tholeiitic and calc-alkalic volcanic rocks. Stoughton-Roquemaure - Comprised of komatiitic, tholeiitic and calc-alkalic volcanic rocks. Deloro - Comprised of tholeiitic and calc-alkalic volcanic rocks and iron formation Pacaud - Comprised of komatiitic, tholeiitic and calc-alkalic volcanic rocks. Precious metal production in the Kirkland Lake Gold Camp has exceeded 40 million ounces (Risto et al, 2008) from around 30 mines. Most of the gold production in the area has come from quartz veins associated with the Kirkland Lake Main Break ("KLMB"), which is interpreted to be a splay structure related to the LLB.

Lithology

Lithology Comments

Mar 10, 2010 (D Guidon) - from Ewert et al. 2009 The Lower Tisdale-Larder Lake assemblage, comprising mafic to ultramafic volcanic rocks with units of chert and interflow sediments, of the Timmins-Kirkland Lake segment of the Abitibi Greenstone Belt is host to the Anoki deposit. The Mineral Resources at Anoki are contained in nine lenses (Lens 1-7, 33 and South) that are located within a 50?100 m thick package of altered, coarse grained basaltic flows in the hanging wall, south and adjacent to the LLB approximately 600 m west of the McBean deposit. These lenses are vertically dipping, east plunging and have a weighted average thickness of 6.6 m (Queenston News Release, December 16, 2009). The coarse grained basaltic flows occur as two roughly equal sized sequences, with the southernmost sequence containing a number of intercalated ultramafic units. The coarse-grained flow sequences are in contact with finer grained basaltic flows and interflow sedimentary rocks to the south and amygdaloidal to vesicular and variolitic flows northward. The variolitic flows continue northward to the sheared ultramafic rocks at the start of the LLB. The basaltic flows both terminate along packages of cherty, graphitic and tuffaceous rocks plus or minus felsic intrusives at their north contacts. Emanating from the LLB and the basal portion of the Anoki deposit, is a splay feature (the South Splay), which diverges from the steeply dipping LLB and flattens to a dip of around 10° to 30° and plunges 20° to 30° to the east. A wedge of strongly altered and deformed tuffs and volcaniclastic rocks is present between the two structures, which hosts a deeper zone of mineralization designated as the Anoki Deep Zone by RPA in their 2004 Report on the Anoki Property. This zone does not form part of the current P&E 2009 Anoki Mineral Resource. In the upper parts of the Anoki Deep Zone, the dominant protoliths are carbonate altered volcaniclastic rocks of uncertain affinity, possibly belonging to the Timiskaming assemblage. Southward, as the wedge widens, more typical basalts and komatiites of the Lower Tisdale-Larder Lake assemblage are encountered. The relationship between the two sequences is unclear due to the wide drill hole spacing and the complexities introduced by local faulting (Queenston, 2003). Timiskaming assemblage rocks are encountered north of the LLB on the Anoki property and this assemblage is represented by a 150 m to 300 m thick package of variably altered volcaniclastic rocks, followed by a sequence of dark, amphibolitic and magnetic mafic tuffs that have a trachytic (alkalic) affinity. The 40 East Zone and the North Break Zone occur within the volcaniclastic portion of the Timiskaming assemblage.

Geologist: D Guidon

Notes: The deposit is descibed as a series of stacked lenses ranging in size from 50 feet long and 50 feet high to 100 feet long and 100 feet high. The average thickness of a lens is about 20 fett. Lenses are contiguous but variable in orientation and thickness. Location of mineralization is controlled by south dipping fractures formed near the upper, sheared contact of the gabbro parallel to a NE plunging fold axis. Deposit visited on August 1, 1997 under the leadership of L. Cunningham. Observed the pillowed variolitic mafic volcanic rocks southeast of the shaft near the ramp portal (UTM 17 5330950N 586950E. Varioles up to severals centimetres in diameter developed. Some pillows almost filled with varioles. Some varioles flattened. Two sets of fractures observed on the outcrop: 055 degrees and 185 degrees. Sample 96314 collected from muck pile near portal. Portal location approximately UTM 17 5331050N 586500E. Sample shows beached highly altered gabbro? Numerous samples collected in 1990 also listed. These are from the outcrop on Hwy 66.
