About Centenera Mining Corporation

Centenera is a mineral resource company trading on the TSXV under the symbol "CT" and on the OTCQB exchange under the symbol "CTMIF". The Company is focused 100% on mineral resource assets in Argentina and intends to focus its 2018 exploration activities on drill-testing its flagship Esperanza copper-gold project. Other assets, including the Organullo gold project and the El Quemado lithium pegmatite project in Salta Province, are intended to be explored by the Company with the aim of proving project potential and attracting a joint venture partner or a project sale. The Organullo project has approximately 8,000 metres of historical drilling and assay results. Organullo has a geological target range from 19.8 million tonnes grading at 0.94 g/t gold (600,000 ounces) to 31.6 million tonnes grading 0.92 g/t gold (940,000 ounces) using a 0.5 g/t gold cut-off-grade. It should be noted that these potential exploration target quantities and grades are conceptual in nature, that insufficient exploration and geological modelling has been done to define a mineral resource, and that it is uncertain if further exploration will result in the delineation of a mineral resource.
