Utilizing a “Hub & Spoke” Operating Strategy In Nicaragua

Limon and Libertad are prolific mining districts, delivering more than six million ounces of past gold production.

Calibre’s asset base includes multiple ore sources, 2.7 million tonnes per annum of installed mill capacity from two processing facilities, of which only 70% is currently utilized, reliable in-country infrastructure and favorable transportation costs.

The "hub & spoke" operating strategy allows for the debottlenecking of operations and de-orphaning of satellite deposits at rapid rates with low capital costs. The Company will continue to optimize its mine and process plants as it progresses the “hub & spoke” approach to maximize value and allow the Company to quickly translate exploration success into production and cash flow.
