Access Description: Road access to the Junior Lake property from Thunder Bay is via paved provincial highways No. 17 (15 km) and No. 527 to Armstrong, with an overall distance of 255 km. From Armstrong, the Buchanan Forest Products Inc. gravel haulage road (BHR) is taken east to kilometre 105, where a skidder haulage road leads approximately two kilometres to the Landore Camp. In all, the combined distance from Thunder Bay to the property is approximately 360 km.

Exploration History

2003: Landore Canada discovered the BAM Zone while prospecting in June. The discovery was followed up with 3 trenches, a soil sampling program, and a drill program of 6 holes totalling 438 m. 2005-10: Landore drilled 37 DDH totalling 7036.6 m. 2009: Landore conducted geologic mapping and trenching over the BAM Zone. 2014-17: Landore carried out VLF-EM and mag surveys, trenching and channel sampling, geological mapping, and drilled 109 DDH totalling 19,592.8 m. The BAM East zone was found in 2015. 2018: Landore drilled 61 DDH totalling 12,672.5 m. 2019: Landore carried out soil geochemistry and MaxMin, VLF, and magnetic geophysical surveys, and drilled 38 DDH totalling 5945.9 m. 2020-21: Landore carried out a soil geochemistry survey and drilled 102 DDH totalling 24,170.6 m.

Lithology

Lithology Comments

Jan 22, 2018 (Therese Pettigrew) - The main stratigraphic sequence that is observed to host the majority of the gold mineralization at the BAM East Gold Deposit is referred to as the BAM Sequence. The character of this package of rocks has been determined mostly from observations in drill core and in limited exposures in trenches and outcrops in the area. In the immediate deposit area, the BAM Sequence is comprised largely of very fine grained to aphanitic material which has been recorded as clastic sedimentary unit in the drill logs. It is typically a medium to dark green-grey to black colour, contains a weakly to strongly developed foliation, and is characterized by a soapy feel to the touch locally. Characteristic sedimentary textures are generally not well developed in the immediate deposit area. Preliminary geochemical characterization studies suggest that the sediments have been derived from precursor rocks of ultramafic composition.

Mineralization

Mineralization Comments

Feb 21, 2019 (Therese Pettigrew) - The original BAM Gold Zone is located at NAD83 Zone 16, 433473 m E, 5581981 m N. The BAM East zone is located at NAD83 Zone 16, 434910 m E, 5581555 m N. Mineralized structures appear to strike approximately parallel to lithologies, averaging at 280 degrees strike and steeply dipping to the south between -65° to -80°. Gold mineralization remains open along strike to the east and west, and down dip. The gold mineralization is interpreted to reside within a series of tabular shaped zones that are oriented in a roughly en-echelon configuration and are generally parallel to the overall strike of the host rock units. The gold mineralization occurs as a fine dissemination and also is commonly observed in drill core to exist as visible gold that is hosted by very thin, foliation-parallel quartz-rich veinlets, hosted by highly fissile ultramafic sediments of the BAM Sequence, or by foliated rocks of the Grassy Pond Sill. The BAM gold mineralization has been intersected over a total strike length of 3000 m and remains open to the east and west and down dip (Fitzpatrick et al., 2019). Results from the 2017 drill program included 1.67 gpt Au over 9 m in DDH 0417-623, 1.30 gpt Au over 8.84 m in DDH 0417-622, 1.08 gpt Au over 49 m including 2.25 gpt Au over 9.27 m in DDH 0417-621, and 4.71 gpt Au over 6.04 m including 12.95 gpt Au over 1.10 m in DDH 0417-620 (Landore press release Oct 4, 2017). Prospecting samples over the BAM Zone returned assays of 3144 ppb and 5967 ppb and enrichment in As. The mineralized zone exposed in the trenching consists of narrow, anastomosing, locally coalescing, moderately biotitic, variably silicified and carbonatized, variably mineralized shears occurring near the northern margin of a medium- to coarse-grained melagabbro to gabbro sill or dyke in contact with pillowed mafic metavolcanic flows. Mineralization is closely associated with alteration, and consists of 1 to 8%, finely disseminated pyrite and fine needles of arsenopyrite, and locally attains widths of up to 2.50 m. Mineralized grab samples taken from Trench T15 contain up to 11.94 gpt Au and channel samples 1.61 gpt Au over 1.11 m and 4.16 gpt Au over 0.33 m (MacTavish 2004, AFRI 42L05NW2016). Several of the holes intersected similarly sheared, altered and mineralized intermediate dykes, of highly variable thicknesses, that occurred in close proximity to the BAM Zone intercepts. All pyrite-arsenopyrite-bearing zones exhibited anomalous to strongly anomalous Au values and moderately to strongly enriched As values. Low-grade intersections of 1.9 gpt Au over 1.2 m, 2.1 gpt Au over 0.5 m and 2.6 gpt Au over 0.8 m were encountered in drill holes 0403-02, -04, and -05, respectively (MacTavish 2004, AFRI 42L05NW2017). DDH 0403-01: 30.38-30.85 m – 211 ppb Au, >8000 ppm As DDH; 0403-02 : 17.30-17.55 m – 548 ppb Au, >8000 ppm As; 27.30-28.50 m – 1936 ppb Au, 7 ppm As (feldspar porphyry dyke); DDH 0403-03 : 26.60-26.90 m – 106 ppb Au, 3116 ppm As; 46.56-47.25 m – 85 ppb Au, >8000 ppm As;; 47.25-47.82 m – 50 ppb Au, 3687 ppm As (feldspar porphyry dyke); DDH 0403-04 : 48.50-50.37 m – 283 ppb Au, >6450 ppm As; 52.06-52.58 m – 2141 ppb Au, 5969 ppm As; DDH 0403-05 : 36.48-37.23 m – 2622 ppb Au, 3895 ppm As; 46.4-47.15 m – 1917 ppb Au, 7508 ppm As (feldspar porphyry); 47.15-47.90 – 501 ppb Au, >8000 ppm As; DDH 0403-06 : 59.89-60.14 m – 366 ppb Au, 1692 ppm As.
