Rio Tinto’s Nuton, Arizona Sonoran Copper ink joint venture option on Cactus project

The new exploration will allow the firm to expand its existing resources in the southern Puno region.

The company is saying it will buy 6,205 acres of private land by its Santa Cruz copper project near Casa Grande, Arizona.

The JV will explore Serabi's Matilda prospect and other targets in the Tapajos region of Brazil, within its Palito Complex.

The Toronto-based explorer is working towards publishing a resource update on Courvan and the Pascalis deposits in Quebec by June.

Monarch says the results from last year’s drill program confirm that the pit shell and underground resources can be expanded.

The project is expected to provide SSR Mining with approximately 80,000 attributable gold-equivalent ounces.

A new resource estimate underpins the PEA at the Arizona project.

One of Canada’s most successful mining prospectors finds a good chunk of his claims hemmed in on all sides by China Metallurgical Exploration Corp.

That is a 44% increase in contained ounces over earlier estimates.
