The Motherlode 1 showing is a sericite-altered granodiorite rock sample collected near a stream bank in 2017 by J2 Syndicate Holdings. Another sample was taken further upstream and found to be anomalous. in gold and silver.
A sericite-altered Late Triassic granodiorite with a few quartz stringers (less than 2 millimetres thick) graded 0.175 gram per tonne gold, 2.6 grams per tonne silver, 0.22 per cent lead, 0.12 per cent zinc and 0.087 per cent barium (W385810, Assessment Report 37139). Two hundred and seventy-five metres upstream (west) from sample W385810 is an outcrop of gossanous, altered Mississippian Stikine Assemblage volcanic rock with 20 per cent pyrite including pyrite stringers. A grab sample of this material assayed 0.167 gram per tonne gold and 1 gram per tonne silver; base metals were not anomalous (W385709, Assessment Report 37139).
In 2016, a reconnaissance exploration program was conducted by J2 Syndicate Holdings on August 19th prior to staking the Motherlode claim. A total of 11 rock grab samples were collected within the newly named Cash Cow Trend that encompasses both the Chid Creek and Second Creek showings.
The 2017 geochemical sampling survey consisted of a two-day program in August, conducted by two geologists and two prospectors employed by J2 Syndicate Holdings. The purpose of the 2017 program was to follow-up on 2016 prospective results with chip sampling, visit targets delineated by high resolution satellite imagery and to expand the geochemical knowledge of the area. A total of 64 samples were collected during the 2017 field season: 4 chip, 22 rock grab, 3 float, 9 talus fine, 19 soil and 7 silt samples. Samples taken in the Motherlode 1 area in 2017 resulted in this new occurrence.
In 2019, Brixton Metal Corporation expanded their Thorn property through staking and acquisition of several claims over their East Target area which contained seven mineral showings including Ant (104K 032), Bing (104K 035), East Ant Diorite (104K 152), Skarnface (104K 153), Bing Skarn (104K 166), Motherlode2 (104K 183) and Motherlode1 (104K 190).
In 2020 Brixton completed 3,025 metres of drilling within 16 core holes on the new Central Outlaw and West Outlaw zones on their Thorn property. A total of 1473 rock samples and 5588 soil samples were also collected throughout their expanded Thorn property (Press Release, Brixton Metals Corp., Dec.15, 2020). Brixton's East Target western soil anomaly is roughly 3 kilometres by 3 kilometres in area with a minimum of 100 parts per million copper; a central area (roughly 1.75 by 1.75 kilometres in area), within the larger soil anomaly, is greater than or equal to 200 parts per million copper (see Figure 7, Press Release, Brixton Metals Corp., Dec.15, 2020). The Motherlode1 is located about 600 metres northwest of this soil anomaly in an area showing iron oxide or jarosite alteration.
