SPONSOR: Advance Gold AAX.v – Advance Gold controls 100% interest in the Tabasquena Silver Mine in Zacatecas, Mexico. A cluster of 30 Epithermal veins have been discovered, with recent emphasis on exploring a large anomaly to drill. Advance also owns 13.5% of the Kakamega JV attached to Barrick Takeover Offer for Acacia Mining. Click Here For More Info
- Just 215.5 million ounces has been discovered in 41 discoveries over the past decade, compared with 1.72 billion ounces in 222 discoveries in the preceding 18-year period.
S&P Global Market Intelligence’s annual Gold Discoveries report found that gold exploration budgets peaked in 2012, but remain at historically high levels.
Explorers have allocated US$54.3 billion to gold exploration over the past decade, 60% higher than the $32.2 billion spent over the preceding 18 years.
Despite the effort, just 215.5 million ounces has been discovered in 41 discoveries over the past decade, compared with 1.72 billion ounces in 222 discoveries in the preceding 18-year period.
Over half of that amount is contained in just 10 discoveries, with Zhaojin Mining Industry Co’s 16.4Moz Haiyu deposit in China the largest.
Other deposits in the top 10 including Barrick Gold’s Goldrush, White Rivers Exploration/Harmony Gold’s JV, SolGold’s Cascabel and Cardinal Gold’s Namdini.
S&P says that even after adjusting for more recently identified deposits that might eventually surpass its threshold for a major discovery, and for major discoveries with potential to expand, it forecasts that the gold in major discoveries might only increase to about 363Moz over the next decade.
S&P Metals & Mining senior research analyst Kevin Murphy said previous research into gold lead times showed that it took about 20 years for an asset to advance from early exploration to production.
“This timeline implies that the reduced discovery rates of the last decade will limit the pool of projects that could come online in 15 to 20 years,” he said.
“Unless discovery rates begin an upswing in the near future, there could be a lack of quality assets available for development in the longer term.
“The declining discovery rate shows the importance of continuing exploration and funding companies responsible for exploration to maintain a healthy future pipeline of assets available for development.”
Majors Barrick and Newcrest Mining reported declines in reserves this year.
Barrick’s reserves dropped to 64.4Moz from 86Moz, mainly due to divestments and reclassification, while Newcrest’s dropped by 3Moz to 62Moz.
Newmont Mining’s remained unchanged at 68.5Moz, though the average grade fell by 5%.
Newmont has increased its 2018 exploration budget to US$350-400 million from $200 million last year, Barrick is boosting its spend to $185-225 million from $149 million, and Newcrest is spending $70-90 million in FY18, up from $58 million.
