This JORC resource is an estimated 3% of total mineralization.

Korab has drilled outside of its JORC resource but will need to do infill drilling to get to a JORC compliant resource for the magnesite outside of the current JORC resource. There's another magnesite deposit called Huandot to the northeast of Winchester with similar grades. If I recall correctly the step out drill holes between Winchester JORC resource and Huandot have resulted in similar grades to those of the two deposits.
Some info on Huandot: https://www.csaglobal.com/wp-content/uploads/2015/05/CSA-Global-magnesite-presentation-MagMin-2015-Conf-20-May-2015.pdf

2017 drilling was not aimed at magnesite but at discovery of other metals like cobalt, silver and zinc to the southeast of the magnesite resource.
