Exploration History

Early 1980s: prospector D.O. Baker carried out prospecting and sampling, and optioned the property to Hollinger Argus. 1984: Hollinger Argus carried out mapping and sampling. 1985: D.O. Baker formed Verse Lake Mining and Exploration Ltd. 1985-86: Glen Auden Resources Ltd. entered into a JV agreement with Verse Lake Mining and flew an airborne VLF-EM and magnetometer survey. 1986: Glen Auden Resources carried out mapping and sampling. 1988: Glen Auden Resources drilled 5 DDH totalling 536 m on the property, including 1 DDH totalling 69.5 m on the Labmin showing. 1989: Placer Dome Inc. conducted magnetic and VLF-EM surveys, and drilled 8 DDH totalling 1405.5 m.

Geology Comments

Nov 29, 2022 (Therese Pettigrew) - On the property, supracrustal rocks define a synformal axis that has been refolded and faulted, probably due to a granite intrusion on the west side of the property, and a granodioritic intrusion on the east side of the property. The supracrustal package consists of a central pile, up to 1200 m thick, of variable felsic (dacitic) distal tuffs and their volcanoclastic equivalents, bounded to the north by predominantly mafic coarse clastic metasediments, and bounded to the south by predominantly felsic to intermediate volcanoclastic metasediments. Innumerable l narrow, amphibolitized mafic sills have intruded semi-concordant with the above mentioned stratigraphy. Several types of felsic to intermediate porphyry dikes and sills are found intruding the felsic tuffs. All the rock types are cut by post tectonic north-northwest trending diabase dikes (Assessment report 41O05SE0008).

Lithology

Lithology Comments

Nov 29, 2022 (Therese Pettigrew) - The coarse ash tuff is found throughout the felsic metatuff sequence. The rocks are quite variable in texture and with increasing schistosity grades into a quartz-feldspar-biotite schist. In general, the rock consists of an aphanitic to fine grained grey-green tuffaceous matrix hosting an average 50% felsic fragments and broken feldspar crystals and rare (less than 5%) dark quartz eyes. Fragments are generally subangular, range up to 4 mm and average 1-2 mm in size. The coarse ash tuff weathers irregularly to a "swiss cheese" type texture. The rock is moderately foliated with up to 5% biotite and sericite defining foliation. In places, sericite content ranges up to 10%. Pyrite is found ubiquitously in this unit as fine disseminations of from 1 to 5%, and where sheared, up to 8%. This is the main rock type hosting both the Labmin and North showings. The quartz-sericite schist is found within sheared portions of the mineralized coarse ash tuff, and tends to host the only significant gold mineralization found to date on the property. The rock is comprised of up to 50% fine sericite intermixed with recrystallized quartzofeldspathic material. Apple green mica of up to 0.5% is common as are up to 5% glassy stretched quartz eyes. Pyrite is ubiquitous in this unit as 3 to 8% streaky disseminations. In the Labmin showing, 1% very fine grained galena was also noted (Assessment report 41O05SE0008).

Mineralization

Mineralization Comments

Nov 29, 2022 (Therese Pettigrew) - Sampling by Hollinger Argus returned 0.066 and 0.042 oz/t Au. Sampling by D. Baker returned 0.277 oz/t Au. Sample 17110 by Glen Auden Resources returned 7852 ppm Zn and 311 ppm Au from a quartz-sericite schist with 7% pyrite, 1% galena, and a trace of green mica. Mineralization mapped and sampled on the property includes (1 to 3%) disseminated pyrite found ubiquitously in the felsic tuffs, and a trace of galena found within a sheared portion of the felsic tuffs (Labmin showing). Pyrite tends to be more concentrated (up to 8%) within the more schistose (or sheared) portions of the felsic tuffs. Alteration within sheared portions includes a strong sericitization generally accompanied by traces of apple green mica as well as patchy silicification. Alteration related to northeast trending faults includes intense silicification and hematization (noted along the northwest side of Shrike Lake). The Labmin showing, located in claim 714690, has been exposed by stripping and was previously extensively plugger hole sampled and grab sampled. Previous sample results have returned geochemically anomalous (hundreds of ppb) in gold as well as a two foot chip sample of 0.018 oz/ton Au and a grab sample of 0.277 oz/ton Au. The showing presently consists of a narrow (8-60 cm) sheared section within and semi-concordant with various thin felsic tuffs. A finely disseminated grey metallic mineral identified as galena is found in one part of the sheared area where it narrows to 8 cm. Assaying of this material has produced variable gold results including 145 ppb Au (Ireland and Luhta, 1985), 0.277 oz/ton Au (Donald O. Baker, personal communication) and 311 ppb Au (Glen Auden sample #17110). The sheared section is a grey siliceous, sericite pyrite schist containing traces of a green mica. A very thin (10-200 cm) and irregular flow banded rhyolite bounds fine siliceous tuffs on the west side of the stripped area, and pyritic and somewhat sheared coarse ash tuff is found m on the east side of the stripped area (Assessment report 41O05SE0008).
