Orosur Mining is an explorer focused on the development of early to advanced-stage assets in South America.

Its flagship Anzá gold project in Colombia was previously a 49/51 joint venture with Minera Monte Aguila (MMA), a corporation owned equally by Newmont (TSX:NGT,NYSE:NEM) and Agnico Eagle Mines (TSX:AEM,NYSE:AEM).

Exploration has revealed multiple gold deposits at the site, which is located 50 kilometers west of Medellin, and according to Orosur sits along Colombia’s primary gold belt.

Orosur also owns several early stage projects: the El Pantano gold-silver project in Argentina, the Lithium West project in Nigeria and the Ariquemes project in Brazil, which is prospective for tin, niobium and rare earths.

Shares of Orosur jumped significantly following a November 28 announcement that it has completed its takeover of MMA. The acquisition gives Orosur 100 percent indirect ownership of the Anzá gold project.

Under the terms of the agreement, Newmont and Agnico will each receive a 0.75 percent net smelter royalty, plus a fixed royalty of US$37.5 per ounce of gold or gold equivalent on the first 200,000 ounces produced.

Since the transaction's completion, exploration has resumed at the Pepas prospect to test high-grade results from a 2022 drill program. On Friday, Orosur announced the delivery of initial assays, saying they confirm the previous results. The samples encountered grades of 5.58 grams per metric ton (g/t) gold over 75.1 meters from the surface, including an intersection of 13.68 g/t over 13.95 meters.

Of the three projects, Rio Grande is the most advanced. The company updated the resource estimate for the site in July, noting that measured and indicated resources had increased to 2,658,000 metric tons of lithium carbonate equivalent, with 2,039,000 metric tons of lithium carbonate equivalent in the inferred category.

If Clean Elements exercises all warrants, it will receive 39.9 percent of outstanding common shares on a fully diluted basis.

NOA plans to use the proceeds of the offering to pay off debts and fund exploration work at Rio Grande.

The firm's properties consist of the Fancamp and Big Daddy claims, along with the Mcfaulds Lake, Koper Lake and Fishtrap Lake projects. All are located within a 40 kilometer radius, and according to the company are home to feeder magma chambers containing chromite, nickel and copper deposits.

Vior is a gold exploration company with a portfolio of assets located in Québec, Canada.

The company’s main focus has been advancing its flagship Belleterre project in Southwestern Québec. The property consists of 635 claims covering an area of 350 square kilometres, and hosts the past-producing Belleterre gold mine, which produced 750,000 ounces of gold and 95,000 ounces of silver between 1936 and 1959.

Vior says that the mineralization trend at the property extends for 6 kilometers, and in addition to gold and silver has demonstrated the presence of copper, lead and zinc.

On September 24, Vior commenced a fully funded 60,000 meter drill program at Belleterre, which will operate through mid-2025. The company says it is the largest drill program at the site since the mine closed in 1959.

The first assays were announced on November 12, and the company reported high-grade gold at depth. The results include highlighted intercepts of 9 g/t gold over 1.2 meters from the Belleterre area, and 4 g/t gold over 1.2 meters from the Aubelle area. Vior said the results confirm the continuity and potential for expansion of mineralization at the site.

The company’s most recent announcement came on Thursday, when it announced that Mathieu Savard, Osisko Mining's former president, will become Vior's new president and CEO. He will be joined by Pascal Simard, who was Osisko’s vice president of exploration. Simard will hold the same role at Vior.
