The Second Creek prospect is underlain by Middle to Late Triassic quartz dioritic rock. The creek itself forms a rough or subparallel boundary between quartz dioritic intrusive rock on the south and undivided Triassic to Jurassic intrusive rocks on the north which extend just north of Chid Creek, and encompass the Chute prospect (104K 151). Late Triassic granodiorite is in contact on the north with the undivided intrusive package. Pendants or rafts of Mississippian and Pennsylvanian undivided volcanic rock of the Stikine assemblage occur within the intrusive bodies.

Carboniferous intermediate to mafic tuffs are intruded by Triassic foliated diorite. The rocks are cut by the Ultramafic (Highway) Fault. Within the diorite, quartz veins, 10 to 20 centimetres wide and several metres long, contain pyrite and chalcopyrite. A sample assayed 13.7 grams per tonne gold and another assayed 53.0 grams per tonne silver (Assessment Report 13983).

The widest structural target located occurs on 2nd Creek (Assessment Report 23431) and consists of a thirty metre wide iron-carbonate alteration zone exposed on both sides of the creek - over about eighty metres along strike. The zone strikes at 145 degrees and dips steeply to the southwest. Mineralization consists of disseminated pyrite associated with quartz-carbonate stock work veins, and several amorphous to gray quartz veins which host the gold values. The best gold value (1992) is 34.8 grams per tonne across a ten centimetre quartz vein on the north bank of the creek (Assessment Report 23431). Trenching along the south bank uncovered a one metre quartz vein that returned 1.74 grams per tonne gold across 10.5 metres including 1.5 metres of 8.57 grams per tonne gold (Assessment Report 23431). The quartz veins appear to pinch and swell along strike.

Geochemical surveying in 2016, by the J2 Syndicate, led to the conclusion that a gold-silver-copper trend, the Cash Cow Trend, encompassed the historic Chute (Chid Creek) (104K 151) and Second Creek showings. The Cash Cow Trend is underlain by extensively fractured diorite with chlorite and minor hematite along fracture surfaces. The trend is located below tree line and is obscured by a thin veneer of glacial till, so exposure is limited to canyons along drainages. Mineralization exposed in two drainages separated by 1.4 kilometers along strike have returned bedrock grab samples assaying up to 1.3 grams per tonne gold and 1.2 grams per tonne silver respectively, and remains open.

J2 Syndicate reports in 2017 that a 75-meter-wide northwest trending fault zone with paralleling and crosscutting sub ductile shears is exposed in canyon walls at the south end the Cash Cow Trend (Second Creek area). The 75-meter-wide zone is strongly oxidized with iron carbonate alteration containing abundant epigenetic banded quartz-carbonate veins, breccias and quartz stockworks with disseminated fine grained sulphides. A 2-meter wide cross-cutting carbonatized shear with abundant fine-grained pyrite-arsenopyrite in a quartz-calcite breccia returned 0.48 grams per tonne gold (Assessment Report 37139). A system of anastomosing shear zones exists for over hundreds of meters across section with paralleling shears observed over 400 meters across strike to the east, returning assays of up to 0.36 and 0.51 grams per tonne gold respectively, and remains open (Assessment Report 37139).

Work History

See Chute (104K 151) for related geological details and Nie (104K 081) for details of early work in the area.

The Second Creek area was explored by Chevron in early 1980s as the Nie 8 claim when mineralization was discovered associated with sulphide veins which have pyrite, chalcopyrite and quartz. Stetson Resource Management was active in the Nie 8 area in 1988 and prospected and sampled the area. In 1989 limited exploration was reported to have been carried out for assessment, including geological mapping and rock sampling. In 1993, trenching, prospecting, geochemical sampling and geophysical EM/Mag grid surveying were carried out on the Chid claims for Allan Resources Incorporated. See Nie (104K 081) for a history of work in the region.

In 2007, Paget Resource collected six rock samples from the Second Creek showing area which confirmed the presence of high gold. These high values in samples 147466 and 147467 are associated with strong iron carbonate alteration and quartz veining with minor pyrite in sheared diorite. Sample 147467 assayed 34.80 grams per tonne gold and 66.9 grams per tonne silver (Assessment Report 29345).

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. The purpose of the 2017 program was to follow-up on the 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. In 2017, the Cash Cow Trend, yielded a high of 1.215 grams per tonne gold, 4.1 ppm silver and and 0.092 per cent copper along Second Creek (Assessment Report 37139).

In 2020, Brixton Metals Corporation completed a program of geochemical (rock and soil) sampling, a 12.5 line-kilometre ground induced polarization survey, a 715 line-kilometre airborne magnetic and electromagnetic survey and 19 diamond drill holes, totalling 5292 metres, on the area of as part of the Thorn property. Drilling was performed on the Outlaw (MINFILE 104K 176) occurrence area.
