The historical estimate was prepared using wireframe models for zinc thresholds, with grade interpolation completed using the inverse power of distance method. The reliability of the historical estimate is considered reasonable, but a qualified person has not completed sufficient work to classify the historical estimate as a current mineral resource and the Company is not treating the historical estimate as a current mineral resource. To upgrade the historical resource to a current resource a constrained mineral estimation should be constructed by a qualified person. Nova intends to use this work to guide further exploration on the Lara Project.
