Vertigo target

Location & Access

Located in the central part of the JP Ross property approximately 75 km south of Dawson City and 360 km northwest of Whitehorse in west-central Yukon. The Property is road accessible from Dawson City, and Henderson airstrip located 6.5 km to the north provides small fixed-wing plane access.

The Vertigo target comprises at least 6 mineralized structures over a 1,500 m x 650 m area and consists of west-northwest striking, steeply south dipping zones of quartz veining, brecciation, and fracture-controlled mineralization comprising disseminated to vein-controlled semi-massive sulphides including arsenopyrite, galena and pyrite and locally visible gold.

Vertigo was first identified as a prospective target area by Underworld Resources Inc. (“Underworld”) in 2009 through early-stage soil geochemistry sampling and geological mapping and prospecting, with rock chip samples of quartz veins returning 1.3 g/t Au. In June 2010, Kinross Gold Corporation (“Kinross”) acquired Underworld and continued exploration on the JP Ross property, including the Vertigo target. Exploration work on Vertigo in 2010 included additional soil sampling, prospecting and surface rock sampling, mechanical trenching (10 trenches, 698 m) and diamond drilling (4 holes, 521.7 m). Prospecting confirmed the presence of gold in quartz vein float, with two grab samples returning 5.37 g/t Au and 8.08 g/t Au. Chip sampling of trenches returned anomalous gold generally ranging from 0.10 to 0.20 g/t Au over widths of 5-30 m, with a best interval of 1.05 g/t Au over 45 m, including 4.06 g/t Au over 10 m in trench JRVE10T0008. Diamond drilling intersected relatively narrow (1-2 m) mineralized zones of generally low grade (< 0.5 g/t Au). The best interval was in hole JRVE10D0003 which returned 17.85 g/t Au over 1.0 m in a vuggy quartz vein and silicified breccia zone from 103.0-104.0 m.

In June 2017, the Company acquired all of Kinross’s projects in the White Gold District including the JP Ross property. In 2018 and 2019, the Company carried out extensive drilling programs on the Vertigo target which included rotary-air blast (RAB) drilling (1448.9 m in 25 holes), reverse circulation (RC) drilling (2551.3 m in 36 holes), and diamond drilling in 2019 (9568.5 m in 46 holes).

Highlights of the RAB and RC drilling included:

RAB Drilling:

RC Drilling:

The 2018 RAB and RC drill holes were drilled to both the south (180° azimuth) and north (0° azimuth) at dips of -55° to -65°. This initial round of drilling confirmed that the primary mineralized structures are dipping steeply to the south, hence all 2019 RAB and RC holes were drilled to the north (0°-20° azimuth). It is apparent that the 2018 RAB and RC holes that were drilled to the south drilled partially down-dip on the mineralized zones, thereby exaggerating the thicknesses.

Diamond Drilling:

The 2019 diamond drill holes were drilled predominantly to the north-northeast (020° azimuth) to test the interpreted steep southerly dip. Highlights included:

Since 2019, exploration work at the Vertigo target area has been limited. In 2020, 6 trenches were excavated as part of a phase 1 and phase 2 trenching program on the JP Ross property. During phase 1, an 8-ton tracked excavator dug 4 trenches at Vertigo and during phase 2, a small CanDIG mini excavator dug 2 trenches. The phase 1 trenches exposed narrow mineralized oxidized and vuggy quartz veins which graded 4.51 g/t Au over 1.5 m in trench JPRVER20T016, 0.91 g/t Au over 2.0 m in JPRVER20T017 and 2.78 g/t Au over 1.8 m in JPRVER20T018. Phase 2 trenching produced the most encouraging results with trench JPRVER20T020 returning 2.16 g/t Au over 21.0 m which included two higher grade subzones of 5.69 g/t Au over 3.0 m and 4.15 g/t Au over 5.0 m. The trench ended in mineralization to the south, so the zone remains open in that direction. This latter mineralization is associated with a southeast-trending gold-in-soil anomaly that remains open along strike to the southeast. Also in 2020, a single RAB hole was drilled at Vertigo with hole JPRVER20RAB-026 intersecting a zone grading 1.82 g/t Au over 3.05 m from 1.52 m.

In the coming months, the Vertigo data will be reviewed to help plan next steps which if warranted, may include additional drilling to test the interpreted southeast extension of the Vertigo zone, as well as on the main zone itself.

Note: All reported widths are those measured along the length of the drill hole and/or trench. True widths are currently unknown.
