Willie Jack

Introduction

A NEW GOLD DISCOVERY IN BRITISH COLUMBIA’S LAST FRONTIER

The Willie Jack Property covers 3,503 hectares and is 100%-owned by Goldstrike Resources with no underlying royalties or payments. Willie Jack is a regional grassroots exploration target, generated in house by Goldstrikes’s exploration team. The property is situated in a remote part of northwest British Columbia that has seen limited gold exploration to date. The area was briefly looked at in the early 1970’s as a Copper Porphyry target with numerous Cu showings discovered but no assays for gold. Goldstrike believes gold and silver was overlooked during the early 1970’s exploration program at Willie Jack, as gold price was at historic record lows (<$250 / oz inflation adjusted) during this time period.

The property covers a strongly anomalous regional geochemical Au-As-Sb signature hosted in a geological setting that shows potential for both porphyry and intrusion-related gold deposits. The property is situated at the headwaters of a historic placer gold-bearing creek and covers a Jurassic age granite pluton that intrudes Paleozoic sediments.

In the summer of 2020, Goldstrike conducted a first pass, reconnaissance prospecting program to evaluate the property for its gold potential. The program was successful in discovering widespread gold mineralization across 6 kilometres with rock grab samples assaying up to 164 g/t (4.78 oz/ton) gold and soils samples assaying greater than 0.8 g/t gold. The widespread gold values obtained in the first pass program suggest potential for district-scale mineralization in a previously unrecognized area of BC.

Location

The Willie Jack property is located in the Atsulta mountain range in northwest British Columbia, 70 km south of the Yukon-BC border and 130 km northwest of the community of Dease Lake, BC.  The nearest road is the Alaska highway, 65 km due north. The property is located in British Columbia’s last frontier; the remote and difficult access has deterred exploration to date despite being surrounded by significant gold deposits.

History

1912

Placer gold discovered on Willie Jack Creek.

1944

Government geologists conducted a reconnaissance geological mapping and prospecting program in the Atsulta mountain range and discovered abundant mineralized quartz veining with a single sample assaying 2.06 g/t Au and 72 g/t Ag.

1969

Quebec Cartier Mining Company conducted a large regional scale (1800 sq km) stream sediment sampling program that discovered anomalous Cu draining the present-day Willie Jack property. The stream sediment samples were only analyzed for base metals (no gold).

1971

El Paso Mining conducted a geological mapping and prospecting program in the area and identified widespread Cu mineralization hosted both in narrow quartz veins and fractured wall rock (granodiorite and monzonite).

1979

Geological Survey of Canada completed a regional stream sediment sample program but with no analyses for gold, arsenic, or antimony. Dupont Canada Exploration followed up on anomalous tungsten and molybdenum stream sediment samples in the area with no gold assays done.

2000

Geological Survey of Canada re-analyzed the 1979 stream sediment samples for multiple elements; including Au, As, and Sb. These 3 elements are strongly anomalous and spatially associated with the historic placer gold-bearing Willie Jack Creek that drains a portion of the property.

2000 – 2020

No documented exploration.

Geology

Regional

The Willie Jack property is located in the northwestern portion of the Atsulta mountain range within the Intermontane Belt. The property is situated along the regional scale northwest trending Teslin – Thibert strike-slip fault system that juxtaposes and divides the Cache Creek and Quesnellia tectonic terranes. The Quesnellia terrane hosts numerous Cu-Au porphyry deposits along the length of British Columbia; including Copper Mountain, Highland Valley, New Afton, Mount Polley, Mount Milligan, and Kemess. The property is also positioned at the southern fringe of the Tintina Gold Belt that hosts many intrusion-related gold deposits across Alaska and the Yukon. These deposits include Pogo and Fort Knox in Alaska and Brewery Creek and Dublin Gulch in the Yukon. The Willie Jack property covers a large Jurassic-age pluton that intrudes Paleozoic sediments of the Kenda Formation and is cut by several small Cretaceous intrusive stocks.

Property

The claims cover a southwestern portion of the Jurassic age Christmas Creek pluton consisting of diorite and monzonite that intrudes Paleozoic limestone and quartzite of the Kenda Formation. The pluton contains pervasive propylitic alteration with widespread narrow quartz veins containing Cu-Au mineralization. Several small, younger Cretaceous age granite stocks intrude the older Jurassic pluton throughout the property. The pluton is strongly fractured with abundant gossanous steeply dipping, northeast striking joint surfaces containing fine disseminated pyrite with a weak enrichment in gold and arsenic. There is abundant quartz veining hosted along the southern margin of the granite pluton that directly drains into the placer gold-bearing Willie Jack Creek.

Mineralization

A short, 7-day reconnaissance exploration program conducted in the summer of 2020 is the only known modern gold exploration to occur on the property to date. The prospecting and ridge-and-spur soil sampling program resulted in the collection of 185 soil samples and 94 rock grab samples. The program was successful in discovering widespread high-grade gold in rock grab samples over 6 kilometres with assays up to 164 g/t Au and 257 g/t Ag. The mineralization discovered to date shares characteristics of both Cu-Au porphyry and intrusion-related gold deposits.

A few different styles of mineralization occur at the Willie Jack property with the dominant style consisting of copper sulphides and oxides (chalcopyrite, malachite, bornite, azurite) and variable amounts of galena (lead sulphide) and pyrite in narrow steeply dipping quartz veins hosted in the granodiorite pluton. These veins carry the highest gold and silver grades on the property. Bedrock samples of veining have returned assays up to 13.9 g/t Au, 52 g/t Ag, and 1.7% Cu.

The second style of mineralization is also hosted entirely in the granodiorite pluton and comprised of fractured gossanous zones containing abundant fine disseminated pyrite with weak enrichment in gold and arsenic. Prospecting grab samples from the gossanous zones have returned up to 0.54 g/t Au.

The third and final style of mineralization consists of auriferous quartz-arsenopyrite veins hosted in sediments near the granodiorite contact. First pass prospecting along the granite contact returned quartz veins assaying up to 0.51 g/t Au. Furthermore, first pass ridge and spur soil sampling has outlined a robust, 4.5 km long Au-Ag-As +/- Bi-Sb-Te soil geochemical anomaly that coincides with the granodiorite contact and auriferous quartz veins sampled to date. This soil anomaly contains gold values up to 0.8 g/t and silver values up to 1 g/t and remains open to the NW and SE along the granodiorite contact. The geochemical signature of the soil anomaly suggest potential for a gold skarn deposit and is believed to represent the lode source to the placer gold-bearing Willie Jack Creek directly downslope.

This gold skarn soil anomaly has seen no follow up work to date and remains a high priority for the 2021 field season. Detailed prospecting in combination with systematic soil sampling will hopefully expand the anomaly and delineate drill targets for future programs.
