Eurotin Inc. announced successful metallurgical results from a mini bulk sample on Oropesa ore performed by Wardell Armstrong International Ltd. (Wardell Armstrong). Using a cutoff grade of 0.15% tin, the new resource is summarized below. There have been no material changes to the prior announced October 2015 resource except for using a slightly higher cutoff grade that was determined by SRK based on updated technical and economic assessment and moreover 330k tonnes that (based on targeted infill drilling) have been moved into the measured category for mine planning purposes associated with the Company's exploitation application announced earlier in late 2017. The Company also announced successful final metallurgical results from a mini bulk sample from Oropesa ore performed by Wardell Armstrong. Approximately 1.7 tonnes of PQ core from three metallurgical drill holes was used for the testwork programme. Each drill core contained a number of mineralised intersections. Each intersection was weighed, crushed and assayed for tin, iron and sulphur. The results were then used to develop a blending strategy in order to prepare a 1,000kg composite sample upon which pilot plant testing was conducted, with a target grade of 0.7-0.8% Sn (the indicative grade for the initial years of contemplated open pit mining). A full metallurgical balance was generated using the mass pulls and recoveries from the pilot plant work, and the ancillary test work. From this a tin recovery of 74.2% at a combined concentrate grade of 62.4% tin was predicted. 64% of the recovery came from gravity concentration at a grade of 63.2% tin, and the remaining 36% came from tin flotation at a grade of 61.0% tin. The gravity concentrate contained 4.6% iron and 0.2% sulphur, both within concentrate specification limits. The tin flotation concentrates contained 13.7% iron and 1.4% sulphur. The sulphur is within limits, but the iron would be out of specification (normally 8%), which would incur a minor penalty. Regardless, the test work shows that a saleable concentrate from Oropesa was achieved.
