Potential of the Corona deposit as HIGH-GRADE OPEN-PIT
Potential of the Corona deposit as HIGH-GRADE OPEN-PITFirst time I read potential of the Corona deposit as a FUTURE HIGH-GRADE OPEN PIT and/or underground operation.

The Corona deposit is located approximately 2km southeast of the Higginsville treatment plant, and will be accessed via a single 0.95km decline using the Fairplay open pit as a portal location.
The high-grade core of the Corona deposit is located 200m to 350m below surface (see exploration announcement dated May 7, 2012) which warrants access to further determine its true value.
The Corona exploration decline will also provide underground drill platforms for approximately 1km of strike along the highly prospective Higginsville Line of Lode.
The project will require approximately nine months of site establishment and development for an estimated cost of $11 million. This work will provide infrastructure and access to commence high-grade ore development at Corona. »
