Bridget and Isaac targets return promising chargeability and resistivity results, warrants further surveying.

White Gold Corp. March 27 announced an extensive exploration update for two of its early-stage targets within the company's massive landholdings in Canada's Yukon, ultimately identifying multiple prospective anomalies near the world-class Casino deposit.

Focusing on the Bridget and Isaac porphyry targets located on the Pedlar and Hayes properties, respectively, the results of an Induced Polarization chargeability and resistivity survey as well as hyperspectral analysis conducted on rock samples collected in 2022, have given White Gold confidence that all data collected thus far continues to support the idea of a porphyry deposit model.

"We are encouraged by results of the 2023 IP test lines at the Bridget and Isaac targets which identified new anomalies and structures that overall correlate well with the soil geochemistry anomalies and current structural interpretations," said White Gold Vice President of Exploration Terry Brace. "The new IP looked deeper than any previous geophysical surveys and demonstrates potential at depth beneath these large multi-element soil anomalies. The test results warrant full IP survey coverage over the target areas which will aid in mapping these systems at depth in support of future diamond drill testing."

The Pedlar and Hayes properties are situated in the southern part of White Gold's 315,000-hectare (778,382 acres) land package in the White Gold District in west-central Yukon. Located 30 kilometers (19 miles) southwest of Bridget and 40 kilometers (25 miles) west of Isaac from Western Copper and Gold's Casino property, these properties sprawl roughly 40 kilometers (25 miles) and 72 kilometers (45 miles), respectively, from the company's flagship White Gold project.


Located on the Pedlar property, Bridget was first explored by Silver Standard Mines Ltd. and Asarco Exploration Company of Canada Ltd. in the early 1970s following the discovery of Casino.

"The Bridget target has an interesting history as it was one of four top prospects that was first discovered back in 1972 when Silver Standard Mines conducted an extensive 14,000 plus regional silt survey looking for another Casino," said White Gold CTO Shawn Ryan. "During the large regional silt survey, Silver Standard also made the Minto copper discovery and eventually focused all their attention on that target."

A series of regional silt samples, soil sampling, and geophysical surveys by Silver Standard in 1971 and 1972 led to the discovery of a significant molybdenum-copper geochemical anomaly, now known as Bridget. Historical exploration work between 2004 and 2016 also included soil sampling, prospecting, geological mapping, and geophysical surveys.

"I staked the Bridget prospect back in 2004, and since then the property has seen extensive soil sampling programs, airborne radiometric surveys and shallow RAB drilling," added Ryan. "The soil sampling program revealed a large copper, molybdenum and bismuth soil anomaly. The molybdenum anomaly (two to 322 parts per million) measures four kilometers by 1.7 kilometers and coincides with a very discrete bismuth anomaly (two to 154 ppm) of 3 kilometers by 1.4 kilometers and a copper core anomaly (50 to 711 ppm) measuring 2.8 kilometers by 1.3 kilometers."

In 2016, White Gold acquired ownership of the property and has continued to expand the large multi-element (molybdenum, copper, bismuth, tungsten, lead, silver) soil geochemical anomaly that currently measures 3,000 by 4,300 meters.

In 2018, a maiden rotary air blast (RAB) drilling program comprising 10 holes totaling 548.6 meters was completed; however, the holes came up short, testing to a maximum vertical depth of only 70 meters, nowhere near the potential porphyry mineralization at depth beneath the anomalous soils. Porphyry targets characterized by IP chargeability high anomalies remain completely untested.

In August 2023, IP chargeability and resistivity surveys were conducted at Bridget as well as the Isaac target. From this, five chargeability anomalies were identified at Bridget and eight at Isaac.

"A deep penetrating dipole-dipole IP survey was undertaken in summer 2023 with one line over the core of the soil anomaly and the results clearly show a textbook porphyry geophysical signature of resistivity lows and chargeability high anomalies sitting below the anomalous soils," added the CTO. "It's now recommended to follow up with more IP survey lines to cover this large developing porphyry target. I look forward to first diamond drill holes into this exciting target."


Located on the Hayes property, Isaac was first recognized by White Gold as a prospective target in 2021 through soil sampling.

Gridded soil sampling at 50-meter spacing on 100-meter lines was conducted in an area located five kilometers (three miles) south of the Yukon River where a 2017 reconnaissance soil survey identified several isolated anomalous ridge and spur soil samples.

Then, 2021 sampling identified a new geochemically zoned multi-element soil anomaly which was later called Isaac, and measures roughly 2,000 meters east-west by 1,500 meters north-south.

Follow-up geological mapping and prospecting in 2022 returned anomalous copper values from the core area of the soil anomaly, with three grab samples returning from 730.6 – 1269.2 ppm copper.

In addition to the IP surveys, hyperspectral analysis from 17 rock samples at Bridget and 19 samples at Isaac showed anomalous trace element enrichments, including copper, molybdenum, and silver, consistent with proximal porphyry copper-style mineralization.

White Gold is encouraged by the success of the IP test lines in detecting anomalies at Bridget and Isaac at depths from 40 meters to 550 meters. These results have warranted the company to conduct a full IP survey over the target areas which will aid in identifying targets at depth in support of future diamond drill testing.
