Canadian exploration company Durango Resources has secured permits from the British Columbia Ministry of Energy, Mines and Petroleum Resources to produce limestone from its Mayner’s Fortune property located near Terrace in the Canadian province.

Durango is permitted to produce up to 10,000 tonnes (t) of limestone for the next five years from its property 7.5km south of Terrace Airport.

The area covered under the interest includes a 2km-thick metasedimentary sequence that hosts at least six sub-parallel north-to-northeast striking limestone units.

The first limestone unit is claimed to have inferred reserves of 454,000t of 96.3% limestone.

Representative samples from exposed outcrop areas show calcium carbonate levels of up to 99.9% at surface.

Durango plans to undertake additional mapping near the fifth limestone unit, followed by trenching, test drilling and production.

This area can be easily accessed through logging roads and has been mapped and measured at 1.6km long at the surface.

Earlier reports revealed limestone units one and three with high quality and size.

However, Durango is interested in whether the fifth unit has high quality at depth due to its size and accessibility.

Durango Resources CEO and president Marcy Kiesman said: “We are happy that the Ministry of Mines has had time to review our documentation and issue Durango the bulk tonnage permit.

“Our geological team is now working on timing for a site preparation visit to Mayner’s, which will be followed by additional exploration.”  

The company reported limestone discovery at the Mayner’s Fortune project in July 2019.
