According to Mining.com, as of June 30, Australia held the leading position among the year's best gold drilling results, accounting for six of the top ten holes and nine of the top twenty, but the most outstanding results came from Canadian miners. The ranking is scored by intersection thickness multiplied by grade.
Wesdome Gold Mines achieved significant results from drilling at its Kiena gold mine in the Val-d'Or region of Quebec, Canada, and the company has begun paying dividends.
The company announced on June 25 that hole N127-7035 intersected 2.9 meters grading 2,349.88 g/t from 76.6 meters depth in the Kiena Deep zone. That was enough to place the result first in Northern Miner's top 20 gold drilling results for the first half of the year, with a score of 6,815 gram-meters per tonne.
Anthea Bath, the company's CEO, said that last year the completion of a new underground drilling platform at Kiena expanded the company's reach, improved drilling angles and provided access to targets that could not previously be drilled.
Before mid-year, the company had completed about 21,000 meters of drilling at Kiena, and underground mining is already producing gold. The Toronto-listed company hopes Kiena will produce 90,000-100,000 ounces of gold in 2025, almost half of its 190,000-210,000 ounce production target.
Exploration work is “going very well”, Bath said in a statement. “Drilling so far has validated our geological model and further consolidated the potential to expand the existing resource.”
In second place was New Murchison Gold's Garden Gully project in Australia. The company's April 30 announcement said hole NGGRCDD974 intersected 0.28 meters grading 17,563.69 g/t from 251.4 meters depth, giving it a score of 4,918.
The Garden Gully gold mine is located in Western Australia's resource-rich Murchison gold belt, surrounded by several mines, with five gold processing plants within 200 kilometers. The project covers 677 square kilometers and includes the Abbotts greenstone belt.
Along the belt, the project hosts several gold prospects, the most advanced being Crown Prince. A November 2024 update on the deposit showed indicated mineral resources of 1.51 million tonnes grading 4.6 g/t, or 226,000 ounces of contained gold, and inferred resources of 693,000 tonnes grading 2.4 g/t, or 53,000 ounces.
The company said total gold resources stand at 279,000 ounces, a 16% increase over the February 2024 estimate.
In third place was Genesis Minerals' Gwalia gold mine in Western Australia. The company's April 8 announcement said hole UGD2504 intersected 0.4 meters grading 10,800 g/t from 374.5 meters depth, giving it a score of 4,320.
Gwalia was acquired by Genesis Minerals from St. Barbara in mid-2023. At 1,600 meters deep, it is Australia's deepest gold mine and the world's deepest truck-haulage mine.
In an investment presentation in August, the company disclosed that Gwalia has measured mineral resources of 3.7 million tonnes grading 4.3 g/t, or 520,000 ounces of gold. The company said there is “excellent” potential to expand reserves by converting 2.6 million tonnes of measured and indicated resources.
Two Canadian miners made the top five — Alamos Gold and OceanaGold — with drilling intersections of at least 6 meters, indicating more minable ore.
Alamos Gold announced on January 13 that hole 89046142 at its Island gold mine in northern Ontario intersected 6.8 meters grading 584.2 g/t from 153.6 meters depth.
Announcing the drilling results, CEO John McCluskey said that in terms of the scale of high-grade intersections, the past year's drilling at Island has been the best in the project's history.
“The main ore body is uncontrolled laterally and at depth, and a large number of high-grade ore bodies have been newly discovered in undelineated structures adjacent to the main ore body. We believe this growth trend will continue,” he added.
OceanaGold's Haile gold mine in South Carolina, USA, also ranked highly. The Vancouver-based miner announced on February 24 that hole UGD0073 intersected 22.95 meters grading 149 g/t from 244.5 meters depth.
As a result, OceanaGold increased the exploration budget for the area by 20% to US$10 million, according to CEO Gerard Bond. It is the largest annual exploration budget at Haile since the mine began production in 2017.
