From a recent analyst report:

"Probe is exploring both open pit and underground potential that could extend
well outside diorite hosts previously exploited and the property currently hosts a
small 770koz inferred resource at ~2.6g/t split roughly 50/50 between open pit
and underground. Nearly 90% of the ounces are within the New Beliveau deposit.

With a large drill program underway and sufficient near-term funding, PRB will
likely garner interest from the broader market given the large land package and
favorable jurisdiction, but it is still in the early stages. An updated resource is
planned for late 2017 and could be the next data point for resource potential at
the project."

"Early stage exploration." Use this oportunity to buy more shares.
