Drilling stepped out in several directions, identifying a new parallel structure about 300m north of previous drilling, with no other drill holes in the surrounding area.

The company said Monday hole JPRVERRC18-016 returned 9.19 grams per tonne (g/t) gold over 9.14m from 54.86m depth, including 17.2g/t gold over 4.58m from 54.86m depth, and 31g/t gold over 1.52m from 56.39m depth, before ending in mineralisation.

Surface sampling have also identified new zones of high-grade gold mineralisation in the areas surrounding the Vertigo target, further expanding the footprint of the mineralised system to 2,200m by 650m, as well as on other targets along the structural trend which has now been traced over 18km on the JP Ross property.

Surface samples included 304.3g/t, 156.2g/t and 105g/t gold, with seven samples grading over 50g/t, 16 samples grading over 10g/t and 29 samples grading over 2g/t. These samples returned grades among the highest ever encountered in the White Gold District, the company said.

"The widespread distribution of high-grade material found in the area is among the most impressive in the Yukon and this is unfolding as a large-scale gold system which is just beginning to be uncovered.

"The structural zones that host high-grade mineralisation on the Vertigo are showing strong continuity in both strike extent and mineral tenor, and highlight the potential for expansion of the known mineralisation and additional new discoveries in the area," said VP for exploration Jodie Gibson.

These results significantly increase the size and scale of the company's recent discovery on its JP Ross property, which it discovered through its unique systematic and data driven regional exploration approach, backed by partners Agnico Eagle Mines and Kinross Gold.

Shares in Toronto-quoted White Gold rose as much as 15.6% in the afternoon trading Monday to hit an intra-day high of C$1.48, before settling at $1.35, up 7c or 5.47%. The company has a market value of $155.66 million.
