CASCADERO UPDATES PROGRESS ON THE DEVELPOMENT OF TARON CESIUM PROSPECT IN NORTH WESTERN Argentina
Subsequent to the Company's receipt of the University of British Columbia's (UBC) Hydrometallurgical progress report in December 2015 and Cascadero's filing of a provisional patent application in January 2016 by the Gowling WLG (Canada) LLP Vancouver office, the Company entered into a consulting agreement with Rod McElroy Ph.D. and continued an existing consulting agreement with Colin Oloman, UBC Professor Emeritus. The objective of the consulting agreement is to estimate the reagent and energy consumption and costs that were used and consumed in the UBC flow sheet and project it to a commercial scale. The UBC research started with the acid leaching of a ground composite of Taron cesium bearing drill core from the 'B' horizon of HQ core hole TAR-09-04.
The objective of the Hydromet study was to determine if the sequence of chemical steps outlined in the UBC flow sheet could produce Cesium Hydroxide (CsOH) and if so, to produce Cesium Formate (HCOOCs) as a next step. Both steps were achieved successfully using 'off the shelf' reagents. A preliminary estimate of the commercial cost of producing CsOH is not fully known at this time and is the objective of the McElroy - Oloman report which is expected in late June.
The Company has now entered into an agreement with BMW Geoscience LLC in Washington, to model the Taron resource. The Company has completed a data transfer to BMW which consists of data from seven core holes totalling 907 metres of HQ drilling. This extensive assay database also includes ~6,800 metres of excavator trenching and ~1,400 metres of hand trenching completed in 2005 to 2007. BMW is modeling the cesium assay variography and the geology of the Cs in drill holes and trenching data to outline the most prospective area for developing the most economical mining exploitation of the deposit. The Company has also retained Pacific Geomatics to prepare base maps for BMW's modelling study and this will enable the Company to decide on the optimum areas of the property to conduct further core drilling to establish a NI 43-101 compliant resource.

On receipt of BMW's resource model the Company also intends to resume surface work with an excavator trenching program to further determine the extent and continuity of higher grade mineralization, preparatory to mining a bulk sample for metallurgical test work at commercial scales.

In 2007, G. McCunn P. Eng prepared a conceptual engineering study on the Taron deposit. This study is being revisited with a view to retaining a mining engineer or company to review and update costs and applicability of the equipment in the study, the size and nature of the mining method, possible impact of onsite removal of detritus from the mineralized body, the size and nature of the leach circuit, treatment of the waste stream, tailings and waste storage and maintenance and operating personnel. The study will also address all operating costs to the point of shipping the targeted cesium compound, Cesium Hydroxide, from the site to world markets.
It is anticipated that a fully equipped remote camp will be required at the site as the work force will need to be brought in from a larger population base as there is no community or transient population within 50 kms of the Taron showing. Obtaining a social license by consulting with all interested parties is a document required by the Salta Province as part of the mine permitting process. The Taron Environmental Impact Assessment report is current.
