Dewdney Trail Property


The road accessible Dewdney Trail Property is located 30 km northeast of Cranbrook, British Columbia and covers more than 10,000 hectares over a 14 km strike length of favourable geology with gold, copper, zinc, lead and/or silver deposit potential.


In 1864, placer gold was discovered in Wildhorse Creek and started a gold rush in the Cranbrook area. Anecdotal information suggests at least 1.5 million ounces (46.7 million grams) of gold have been recovered from the creek; however, no corresponding lode gold deposits of any size have been discovered in the rock, suggesting the Wildhorse Creek Area has undeveloped potential for gold deposits. The Dewdney Trail Property is located upstream from placer deposits in Wildhorse Creek and may host the source of the placer gold.

Since 2010, PJX has consolidated 100% ownership of the mineral rights to claims comprising the Dewdney Trail Property.

In December 2010, RIT Minerals Corp. completed a 43-101 Technical Report (the “43-101”) on the Dewdney Trail Property for the PJX. A copy of the Technical Report was filed on SEDAR in 2011 and is available in the Company’s filings on SEDAR (

PJX has since compiled historical data and infilled data gaps with prospecting, mapping, geochem soil, silt and rock sampling, geophysics, and targeted trenching and drilling to help identify the most promising areas to host potential gold and base metal (copper, zinc, lead) deposits.

In 2021, PJX optioned the right to acquire a 100% interest in the historical Estella Mine from Imperial Metals over a 5-year period. The Estella Mine closed in the 1960s. The mine produced zinc, lead and silver in concentrate from a vein similar in composition to veins that occur proximal to the Sullivan Mine that is located 24 km west of the Property. The small Estella Mine Property is located within the outer boundary of PJX’s large Dewdney Trail Property.

Also in 2021, PJX had Expert Geophysics fly an 895 km airborne survey with a tight flight-line spacing of 100m to be able to identify and define shallow and deep targets across the entire Dewdney Trail Property.

Exploration Potential

Exploration has identified potential for intrusive related gold-copper-silver targets in the Estella Basin, Sullivan type (zinc, lead, silver) base metal targets at depth under Lewis Ridge, and orogenic gold targets in Tackle Basin area.

Property map shows PJX’s target areas in the Sullivan Mining District and Vulcan Gold Belt, including Estella Basin, Lewis Ridge and Tackle Basin.

Target areas all occur within the hinge and/or limb of a large regional anticline fold structure.

Mineralization occurs in sediments similar in age (Proterozoic) and/or type (turbidites, quartzites) to other deposits such as Telfer, Sukoi-log and Sullivan.

Sediments have been intruded by felsic intrusives (alkalic, calc-alkalic) possibly similar in age (Cretaceous to possibly Eocene) to deposits such as Pebble in Alaska or the Butte and Bingham Canyon mining districts in Montana and Idaho, respectively.

More than 10 km of favourable geology with potential to host orogenic gold mineralization have been identified.

Estella Basin, Lewis Ridge and Tackle Basin Target Areas

Estella Basin target area covers an area approximately 2.5 km x 3 km.

Estella Basin may be a magmatic center with possibly multipole phases of porphyritic syenitic/alkalic intrusives that are Cretaceous to possibly Eocene in age.

Prospecting and mapping, during the summer of 2022, collected 22 rock grab samples of quartz veins in locally altered and pyrite bearing syenitic/alkalic intrusives.

Gold mineralization greater than 100 ppb occurs in 19 of the 22 samples with the highest value being 15,598 ppb (15.59 g/t). Copper mineralization greater than 1,000 ppm occurs in 7 of the samples with the highest value being 1.108 %. Lead, zinc, and silver mineralization are also present in samples with the highest analyses being >100,000 ppm (>10%) lead, 5,060 ppm (0.5%) zinc, and 721 ppm (721g/t) silver. Table below displays analyses greater than 100 ppb gold. Sample locations are shown on the Estella Basin geology map.

The Estella Basin is part of the Sullivan Mining District that has geological similarities to other intrusive related copper-gold mining districts, such as the Butte and Bingham Canyon districts located to the south in Montana and Utah, respectively.

All 3 districts occur along continental scale transverse structures, the Uinta arch/lineament at Bingham Canyon, Great Falls tectonic zone at Butte, and the Vulcan tectonic zone at the Sullivan District.

Sulphide rich Proterozoic age sediments that occur in the Butte mining district are the similar to the Estella Basin and across the Dewdney Trail property. Proterozoic sediments are also considered to occur at depth beneath Bingham Canyon. Sulphide mineralization in sediments can provide a source of sulfur to assist with the formation of copper, gold, silver, and other mineralization in the intrusives.

Silty carbonate sediments on the Dewdney Trail property may be good host rocks for the formation of potential gold, copper, zinc, lead, and/or silver skarn, CRD, or other deposit types that can occur proximal to magmatic centers.

Proterozoic age gabbro sills in the area may form impermeable rock layers which can help enrich copper, gold, silver, and other mineralization by impeding and concentrating rising fluids that transport the metals.

Lewis Ridge target area covers an area approximately 3 km x 2 km in size.

Lewis Ridge area has a multi-element signature of gold, copper, zinc, lead, bismuth, molybdenum, arsenic and silver in soil. (See geology maps with various soil analyses)

3-dimensional modelling of the airborne geophysical survey by Expert Geophysics has identified a strongly conductive MobileMT anomaly with a coincident magnetic signature in a geological environment with potential to host Sullivan type massive sulphide mineralization at the Lewis Ridge Target (see Lewis Ridge Target information below).

During late summer and Fall 2022, approximately 2000 m were drilled as a first phase to test a number of targets along the 3 km long by 2 km wide area of geophysical anomalies. Results of this work are expected to be announced in January 2023 after analytical results are received and compiled.

Tackle Basin target area covers an area approximately 2 km x 2 km in size.

Gold is the dominant element in soils in the Tackle Basin area. (see geology maps with various soil analyses).

Tackle Basin is located in the headwaters of the Wildhorse placer gold creek. It is a large basin with placer gold in the creeks draining the basin.

One favourable gold bearing quartzite-argillite unit ranges from 75 to over 200 m true width. Gold occurs with quartz veins or quartz stockwork zones and silica, sericite and carbonate alteration in the sedimentary unit.

Next Steps

The airborne survey is providing insight into geology and mineral potential that is new to the Lewis Ridge target area, Tackle Basin target area, and the historical Estella mine and Estella Basin area.

Preliminary results from mapping, prospecting and sampling during 2022 support the potential for intrusive related gold-copper-silver type deposits in the Estella Basin. Additional analyses from this work are pending. Drill results from an initial phase of drilling at the large Lewis Ridge target area are also pending.

Next steps will be to compile additional pending geochemical analyses with geological, geophysical and drilling results to plan the next phase of exploration and drilling to test targets in the Estella Basin, Lewis Ridge, and Tackle Basin target areas.

  • Estella Basin target area – 19 rock grab sample results for quartz veins in variably altered and pyrite bearing syenitic intrusives.

  • Lewis Ridge Target, Sullivan type target along Jackleg fault that may be eastern extension of Kimberley fault at the Sullivan Deposit.

  • Lewis Ridge Target – large conductive Mobile-MT anomaly extends for over 2.5 km from Jackleg Fault, similar to how Sullivan deposit extends from Kimberley fault. Jackleg fault is considered to be the possible eastern extension of Kimberley fault at the Sullivan deposit.

  • Lewis Ridge Target – cross sections of Mobile MT data along flight lines indicate that the very conductive core of the anomaly may be as shallow as 400m below surface depending on topography.

  • Lewis Ridge Target – conductive core of Mobile MT anomaly appears coincident with a large magnetic anomaly. Sullivan type massive sulphide mineralization can be conductive and/or magnetic. Horizontal orientation of anomalies suggest that the target area may host folded Sullivan type massive sulphide mineralization at or below Sullivan equivalent geological time.
