THE LAWYERS PROJECT IS LOCATED IN THE PROLIFIC 'GOLDEN HORSESHOE'
The Lawyers Property covers 127 km2 of highly prospective rocks in the northeastern region of the prolific metal-endowed Stikine Terrane, British Columbia, Canada. Magmatic events in Stikine during the Late Triassic and Early Jurassic were the driving source for the development of mineralizing porphyry and epithermal systems. On both the east and west sides of the Bowser Basin the same magmatic and mineralizing events are recognized (Logan and Mihalynuk, 2014), forming an arch of gold and polymetallic mineralization; which is depicted herein as the 'Golden Horseshoe' which includes the Golden Triangle (Figure 1). The Lawyers Project straddles an important stratigraphic horizon between rocks of the Upper Triassic Stuhini Group and Lower Jurassic Hazelton Group that define an important geological unconformity with many of the deposits in the Golden Horseshoe concentrated along it. The project is also located in a proven and profitable mining jurisdiction, only 45 km northwest of the Kemess gold-copper mine (Figure 2).

The Golden Horseshoe provides a visual context for the mines, discoveries and common geology of the Golden Triangle and Toodoggone regions, which forms a prolific metalliferous arch that includes the Quesnel and Stikine terranes.
Exploration on the Lawyers property and the surrounding area began in the late 1960s and peaked in the 1980s, identifying numerous showings, prospects and deposits culminating in the development of the Lawyers gold-silver mine that operated from 1989-1992 and produced 171,200 oz gold and 3.6 million oz silver over the 4-year period. The deposit was never fully mined, or the surrounding area thoroughly explored for gold-silver mineralization. An estimated $50 million in infrastructure remains on the property, including year-round road access.
THE LAWYERS TREND
The Lawyers Trend is emerging as an important +20-kilometre regional scale prospect that follows linear magnetic and radiometric anomalies with a northwest to southeast orientation connecting multiple gold-silver showings across the Lawyers land package (Figure 2). Several lines of evidence now support the potential that this anomaly may represent a regional scale structure providing a conduit for gold and silver bearing fluids.

Towards the northern end of the Laywers Trend are the structurally controlled Cliff Creek, Dukes Ridge, Phoenix, and AGB zones that are located within a large 5 km by 8 km radiometric anomaly that is coincident with potassic alteration, associated with a low-sulphidation epithermal system (Figure 3). The limited historical underground production at the AGB and Cliff Creek zones targeted the high-grade veins associated with this large epithermal system. However, recently acquired data, geological compilation, and reinterpretation has revealed significant potential to add gold and silver ounces within these zones and across the entire mineralizing system. New drill results are providing previously unrecognized bulk-tonnage, near-surface intercepts that envelope the higher-grade intervals of gold and silver mineralization. These results are from within the footprint of the historically mined areas, but also include significant gold-silver intercepts along strike, and at depth. The surface expression of the mineralization is coincident with pervasive potassic alteration, large gold-in-soil anomalies, and anomalous rock and trench results.

- 52.02 g/t Au & 846.44 g/t Ag over 3 m**
- 12.67 g/t Au & 143.39 g/t Ag over 28 m*
Select bulk-tonnage drilling intercepts from the Lawyers Trend include:
- 6.96 g/t Au & 254.70 g/t Ag over 57.9 m*
- 5.76 g/t Au & 128.65 g/t Ag over 33.53 m**

- 3.78 g/t Au & 82.40 g/t Ag over 35.0 m*
- 2.68 g/t Au & 82.57 g/t Ag over 36.5 m*

*** Based on limited information from historical mine level plans and ore block models parts of the results above have been mined. However, both high-grade and bulk-tonnage drill intercepts and surface mineralization extend beyond the known workings and the system remains open along strike and at depth.

2019 EXPLORATION PROGRAM
Building on the success of the 2018 exploration program which included +4,400 metres of drilling, airborne geophysics, rock and soil sampling, and additional claim staking, the Company has greatly expanded the 2019 program scope to a +30,000-metre drill program, targeting +5 million gold-equivalent ounces (gold-silver). As a catalyst for growth, drilling will focus on resource expansion with step-out and deeper drilling in zones that have generated significant results. The second component of the drill program will test large radiometric anomalies with coincident high-grade gold-silver samples throughout the +20 km Lawyers Trend. Additional detailed geological mapping, ground geophysics, soil sampling, prospecting, and alteration studies will complement the substantial drilling program.
