A Proven Track Record

Alfonso and Francisco have been credited with numerous discoveries, from their tenure with the Ned Goodman and the Goodman Group of companies.


La Colorada Gold Mine, Sonora, Mexico


+2Moz of gold and +18Moz of silver

La Colorada Gold Mine, Sonora, Mexico


The initial staking cost for Valdez  was about $30,000 USD.

The current Probable resources of the La Colorado Mine are 435,000 oz. gold and 7,600,000 oz. silver. At $1200 USD/ oz Au & $16 USD/ oz Ag, the gross total gross value of the mine is $643,600,000 USD

Off to a head start: The Alaska Vein

Francisco and Alfonso originally acquired the claims containing the known Alaska vein, a high-grade gold and copper vein bearing similar characteristics to their past discoveries.

Surface sampling and prospecting has demonstrated continuity of the Alaska vein over one kilometre with sampling returning up to 7.22 g/t gold, 1.26% copper and 48 g/t silver.

Where: In the prolific Sierra Madre gold belt which has produced over 80 million ounces of gold from dozens of mines. The project is located on private land near the mining-friendly city of Hermosillo in Sonora State, Mexico, with excellent infrastructure including paved highway access, power, and water.

Why: Alfonso and Francisco are confident about reproducing past successes with this project. They have determined that there is likely parallel veins associated with the Alaska vein and possibly a large deep seated mineralized source. Work underway….

The discovery at La Colorada began with two veins but in between was a large area of disseminated gold which enabled a successful low cost heap leach mining operation

Now Ridgestone Mining Corp has the opportunity to reap the benefits of Alfonso and Francisco’s expertise by earning 100%.

Upside Opportunity

In addition to the well-defined Alaska Vein, a newly discovered mineralized zone to the south presents a significant new form of mineralization. This new style of mineralization, identified as an oxidized breccia zone, has been identified on surface over an area of 150 metres by 150 metres and with surface sampling ranging from 1.0 to 26.0 g/t gold and 0.2 to 0.7% copper. A recently completed geophysical survey has indicated this structure could be part of a significantly larger mineralized structure at depth.
