Point Location Description: Shaft

Location Method: AMIS Site Visit

Access Description: A point 3.33 km north and 5.04 km east of the southwest corner of Taylor Township. The Porphyry Zone deposit exploration shaft is about 100 m north of the Taylor Township concession II/III common boundary road within lot 6 about 200 m east of its western boundary. Access to the shaft is via all weather township lot and concession roads. In addition to the Porphyry Zone deposit, anomalously auriferous gold tenors occur near the shaft in what St. Andrew Goldfields (the project operator) geologists refer to as the West Porphyry Zone (located about 670 m west southwest of the Porphyry Zone deposit shaft in the north part of lot 7, concession 2, Taylor Township) and the South Turney Zone (located about 400 m west of the Porphyry Zone deposit shaft in the south part of the south half of lot 7, concession 3, Taylor Township).



Exploration History

1947: Hollinger Consolidated Gold Mines Ltd. is reported to have fence diamond drilled along the PDFZ in the area. 1962-1964: The PDFZ in the Taylor Tp area is reported to have been diamond drilled extensively (DD-52 - 45,072 ft.). 1964-1973: W.H. Turney: ground magnetic survey, DD-7-2389.7 ft. 1970-1975: Hollinger Consolidated Gold Mines and Hollinger Mines Ltd.:, are reported to have diamond drilled in the area. 1979-1981: Hollinger Argus Ltd. (a reorganization of Hollinger Mines) optioned claims along the PDFZ. The joint venture partners diamond drilled the deposit. 1984: St. Andrew Goldfields: optioned claims on which the Porphyry Zone deposit is located) from Labmin Resources. 1986-2012: St. Andrew Goldfields: purchased from Labmin Res. its interest in claims in the Taylor Twp area, including those claims on which the Porphyry Zone deposit is located. Previous operators are reported to have diamond drilled more than DD-50 -60 000 ft. St. Andrew Goldfields sank through 40' of overburden a 565 foot deep vertical 3 compartment shaft, erected a steel headframe, and established 3 level stations at vertical distance beneath the collar of 200, 325, and 475'.; underground exploration, crosscutting, UGDD-39,767 ft., surface drilling 42,484 ft.; stockpiling of 16,154 tons of ore. 2014-2015: bulk sample of 17,540 tonnes processed from the 1004 lens. The bulk sample achieved an average head grade of 9.01 g/t Au and a mill recovery of 97.4%. The Holt Complex, consisting of Holt, Holloway and Taylor mines ceased production on April 2, 2020, as part of Kirkland Lake Gold's response to the COVID-19 pandemic, whilst continuing the strategic review of the Holt Complex.

Geology Comments

Dec 07, 2015 (C Salo) - Bedrock in the deposit area is completely glacial drift and/or glaciolacustrine deposit covered. The Shoot Zone deposit is within or marginal to the Porcupine-Destor Fault Zone (PDFZ), a regional scale basement structural and/or stratigraphic discontinuity which is characterized by the presence of lithologically distinct fault/shear bounded blocks of variably altered weakly metamorphosed volcanic, clastic sedimentary, and alkalic igneous rocks.The PDFZ in west Taylor Township strikes about 080, dips steeply south, and is spatially associated with (but does not always coincide with) a lithologic contact which bounds generally east striking, steeply dipping, and south facing subaqueously deposited weakly metamorphosed tholeiitic and komatiitic volcanic and interflow sedimentary rocks of the(Archean) Stoughton -Roquemaure Group (to the south) from generally east striking, steeply dipping, and north facing weakly metamorphosed turbiditic sedimentary and intercalated volcanic rocks of the (Archean) Porcupine Group (to the north). Regional metamorphic grade in the area is greenschist or lower, except marginal to felsic intrusive bodies, where amphibolite grade contact metamorphic aureoles may be developed. Intrusive rocks in the area include a wide variety of felsic dike and sill-like bodies, ubiquitous narrow (rarely wider than a few tens of metres) generally north striking diabase dikes of the Matachewan swarm, and lamprophyre dikes. A recent geophysical survey of Taylor Township failed to detect any anomalous bedrock conductors which coincide with the location of known auriferous material near the exploration shaft.

Lithology Comments

Dec 07, 2015 (A Wilson) - The rock lithology on the Taylor property can be generalized, from south to north as follows: 1) mafic volcanic rocks, which are relatively undeformed and unaltered; 2) ultramafic and mafic volcanic rocks, which vary from weakly to strongly deformed and altered and contain felsic to intermediate porphyritic intrusions of varying shapes and sizes; 3) metasedimentary rocks; the thick footwall sequence of metasedimentary rocks is interpreted to represent the footwall of the DPFZ on the Taylor property. This general sequence is simplified and in detail and particularly in the mid -section, the property geology is much more complex. Within the mid-section of the property, ultramafic and mafic rocks are interlayered, and exhibit varying degrees of deformation and alteration, sometimes intense, and are complexly intruded by dominantly felsic porphyritic intrusions. This sequence hosts the gold mineralization on the property.

Mineralization Comments

Dec 07, 2015 (A Wilson) - The Taylor mineralization is in close proximity, within the hanging wall, to the DPFZ. Over a strike length of 2.3 kilometres there are three mineralization zones that have been identified. From east to west these are: a) The Shaft Zone, with gold mineralization associated with felsic intrusive rocks. b) The WPZ, a system of stacked lenses, with the gold mineralization associated with felsic intrusive and altered mafic-ultramafic rocks (Green Quartz Carbonate). c)The Shoot Zone, with gold mineralization hosted by argillaceous metasedimentary rocks within a package of green quartz carbonate. Gold commonly occurs as relatively coarse-sized free gold in quartz, but also occurs as fine particles, which may be intimately associated with sulphides (particularly pyrite and locally, arsenopyrite) both in quartz-carbonate veins or in surrounding altered host rocks.


Dec 07, 2015 (C Salo) - Anomalous Au tenors are reported to occur within: a) green carbonate (fuchsitic carbonatized ultramafic igneous rock) where it is transected by quartz-carbonate veinlets; and (more commonly) b) fractured graphitic and Mo (MoS2 assays as high as 3% are reported) cherty porphyry or altered basalt. Anomalous Au tenors within green carbonate are reported to be associated with a) disseminated anhedral pyrite which contains fracture controlled native Au blebs (i.e. the Au is nonstoichiometric); and b) graphite-Mo filled fractures which contain visible (cg native) Au. Anomalous Au tenors within porphyry are associated with disseminated visible Au and with visible Au bearing q-carb stringers. Within porphyry, the greatest Au tenors are reported to occur within material containing elevated graphite contents. The porphyries are hypothesized to be either extrusive or intrusive or metasomatic in origin. Gold mineralization is interpreted to be the product of relatively late stage focussed discharge of q-carb veinlet depositing metamorphic or magmatic fluids within mainly (but not exclusively) fractured (brittly deformed) felsic porphyry which was previously pervasively altered and made rheologically competent in a manner reminiscent of either: a) spilitization (early pervasive sodium metasomatism (as albitization), silicification, and hydration followed by later potassium metasomatism (as sericitization)) ; or b) fenitization (metasomatic addition of P and F (as fluorapatite), REE, Zr, Hf, Th, and U) developed within or marginal to a dynamic PDFZ.
