5 Shafter Silver Project Acquired by Aurcana Corporation in Owned by US subsidiary Rio Grande Mining Company. Developed by Aurcana 2011 to Limited commercial production starting in December Project placed on care & maintenance December 2013, in part due to the decline in the price of silver. Mobile equipment sold. Site maintained by 3-man crew. Important permitting remains in place. Project database reviewed in detail during 2014 and Database updated to include more historic information, maps and reports, wire frame model, redevelopment scenarios. Operating records archived at site. By its nature Shafter is highly leveraged to the price of silver. Resource estimate effective December 11,

14 Shafter Mineralization Considered to be a Carbonate Replacement Deposit, northern Mexico style Stratabound manto in Permian near post-permian / pre-cretaceous unconformity. (Mina Grande Fm) Mineralization likely occupies an ancient karst feature, and was initially mixed Ag-Pb-Zn sulphide minerals. Oxidation now extends to a depth of at least 1000 feet. Mineralization largely confined a zone near the unconformity. Does not extend up into Cretaceous. Basis of 2013 exploration drilling: Megaw championed the concept of Feeders and Bleeders that connect several mantos. Drill holes targeted postulated crosscutting fracturehosted mineralization which would lead to another manto at depth. Drilling was designed to test this concept. Some encouragement but never fully tested. Manto Bleeder Feeder 14

15 Geology Of Shafter - Stratigraphy Tertiary volcanic rocks cover a large portion of the area and lay unconformably upon an inlier of Permian and Cretaceous strata. Lower Cretaceous - Presidio and Shafter Formations Shafter Fm: Alternating fossiliferous and nodular limestone. Presidio Fm: sandstone and conglomerate (clasts from underlying Permian units and fossiliferous limestone. Permian - Mina Grande Formation Mina Grande is composed of massive to thin bedded limestone & dolomite - wackestone to packstone and carbonate mudstone. Ross Mine Fm. Host to Shafter Interbedded bioclastic packstone to wackestone (with chert nodules at top), carbonate mudstones and bedded quartz sandstone, siltstone and shale. 15

18 Geology & Mineralization Regional geology in southwestern Texas is similar to Northern Mexico with a thick Permian to Cretaceous sedimentary basin intruded by Tertiary dykes, sills and stocks Silver-lead-zinc deposits in these basin sequences are carbonate-replacement deposits Shafter mineralization occurs in the upper units of a Permian limestone immediately beneath a Cretaceous clastic unit Mineralization is mainly as tabular replacement bodies along bedding, locally along faults and fractures Mineralization is oxide ; silver occurs mostly as acanthite, argentian jarosite and cerargyrite (83-85% recovery by Merrill-Crowe). Zinc as hemimorphite/willemite, lead as cerrusite. Trace sulphides minerals. Gangue is dolomite, calcite and quartz with varying amounts of goethite. Silver mineralization appears to extend over 6000 feet of length plunging gently from surface to at the historic Presidio Mine to at least 900 feet deep in the Gold Fields Zone 18

21 RGMC Underground 2011 to 2013 Underground ramp started in August 2011 and by October 2013 extended 3,800 feet Stopes were developed off the ramp in 8 areas, with over 4,100 feet of development (821,000 ft 3 ) Mining found the historic resource model unreliable at predicting grades in the Presidio Mine segment Unexpected pre-ww II workings were encountered Unmined Gold Fields extensions appears to be more thoroughly tested and is well-documented Current resource model focuses on geological controls, removing minedout areas, capping grades, composites and using cell sizes that are realistic with respect to mineralized thicknesses and mining conditions Result is a resource model that shows a high-grade linear body that displays good consistency along strike, is relatively variable across its width, and high grade Opportunities exist to add to resource estimate by infill drilling between blocks as well as step-out drilling. 21

Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the estimated Mineral Resources will be converted into Mineral Reserves. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues. The Mineral Resource estimate was undertaken by Paul Tietz, CPG of Mine Development Associates, Inc. ( MDA ) of Reno, Nevada, a qualified person ( QP ) as defined under NI The Mineral Resource was estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM"), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the Standards Committee on Reserve Definitions and adopted by the CIM Council on May 10, Viewers are advised that Technical Report containing the foregoing resource estimate is available on SEDAR ( The report titled Technical Report on the Shafter Silver Project, Presidio County, Texas, and dated January 11, 2016, was prepared for Aurcana by Paul Tietz, CPG of Mine Development Associates, Inc. and Ross MacFarlane P.Eng of Watts, Griffis, and McQuat. Both Mr. Tietz and Mr. MacFarlane are Qualified Persons within the meaning of NI Rio Grande Mining Co/Aurcana Corporation 22

23 Shafter Modelling Snapshot-(2016) Silver mineralization at Shafter occurs as a manto - thicknesses and silver grades are more predictable across the width but are variable along its length. Key features of the Resources Estimate include: The Shafter drill-hole assay database contains 20,006 silver assays from 1,694 drill holes. Of the drill holes, 155 were drilled by Aurcana. The majority of drill holes (992 holes) in the database are underground core holes completed by American Metal Company ( Amax ) prior to Silver grades fall into two natural populations as low- and high-grade silver domains. The low-grade domain is associated with weakly fractured and silicified limestone characterized by silver grades between 0.8 oz Ag/ton and 5.0 oz Ag/ton. The high-grade domain (>5.0 oz Ag/ton) is associated with strongly silicified, fractured limestone. Resource blocks having five percent or greater underground workings were removed from the classified mineral resource. Compositing was done to 4ft down-hole lengths, matching the model block size and honoring all mineral-domain boundaries. Four tonnage factors ranging from 12 to 14 ft 3 /ton were used, reflecting lowgrade, high-grade domains, non-mineralized units and zones of clay or rubble. The reported mineral resources were estimated by inverse-distance to the third power to estimate the grade of each block; ordinary kriging and nearestneighbor estimates were used for comparison and validation. The stated resource is fully diluted to 10 foot by 10 foot by 4 foot blocks and is tabulated on a silver cutoff grade of 4.0 oz Ag/ton. 23

24 Opportunity Aurcana has a strong asset in Shafter Good location, serviced site, project is essentially built Good resource model, development issues identified, realistic plan can now be developed Much of the technical risk has now been identified and dealt with; what remains is manageable Project is highly leveraged to the price of silver, and that is key to any future re-development Company is debt free, with a favourable share structure Aurcana has sufficient cash to pay-down receivables, maintain the property and has a strong technical team under proven leadership.
