Iberian Announces Joint Processing Agreement on White Caps Iberian Announces Joint Processing Agreement on White Caps Tailings Project Edmonton, Alberta, March 28, 2017 - Iberian Minerals Ltd. (the ``Company`` or Iberian) (TSXV: IML) (OTCQB: SLDRF) announced today that its 100% wholly owned subsidiary, Mineworx Technologies (Mineworx) has entered into a Binding Letter of Intent (LOI) to form a Joint Venture (JV) with Coronet Metals Inc. (TSXV: CRF) (Coronet) to process an estimated 250,000 tonnes of gold bearing historic tails and mine dumps* at Coronets White Caps Gold Project near the town of Manhattan in Northern Nye County, Nevada. Under the terms of the agreement, Mineworx will apply its exclusive license to utilize the EnviroLeach Technologies patent-pending, non-cyanide leach formula. Under the terms of the Agreement, Coronet will provide all necessary funding for the testing and project development. With the commencement of commercial production the Joint Venture shall be responsible for sharing all operational costs and all profits will be shared on a 50/50 basis once Coronet has fully recovered its investment in testing and development costs. Mineworxs share of the JV will be reduced to 35% after a two year period. As per the February 2, 2017 news release by Coronet, detailed mapping and systematic trenching of the tailings and dumps were completed to provide approximately 300 lbs. of representative material for testing. The samples were taken from four primary zones that collectively make up the gold-bearing tailings and mine dumps. The four main zones are identified as; Bill Placer, White Caps Dumps, Pink Tails and Brown Tails. The first series of hydrometallurgical test results on the gold-bearing tailings and dumps was performed by EnviroLeach Technologies and Met-Solve Laboratories (Langley, B.C.) with ALS Global (Vancouver) performing independent verification of the sample solutions and solids. Highlights of the hydrometallurgical test work can be summarized as follows: Head grades of 5.43 g/t on the Pink Tails Head grades as high as 15.94 g/t on the White Caps Dumps (-35 mesh) Recovery % as high as 70.74 % in 6 hour leach cycle and 87.24% in 24 hours on the Brown Tails Recovery % as high as 71.52 % in 24 hour leach cycle on the White Caps Dumps (-35 mesh) Compared to hydrometallurgical test work performed at a lab in Denver in 2012 on similar samples employing cyanide, the EnviroLeach process shows significant improvement in recoveries using the EnviroLeach solution vs. cyanide. The EnviroLeach residence time was 3 times shorter (24 hours vs. 72 hours) with 295% better recoveries on the Pink Tails, 278% better on the Brown Tails, 170% better on the Bill Placer and almost identical recoveries on the White Caps Dumps. Approximately 5kg of material from each zone was provided to EnviroLeach for testing. Bottle roll tests were done on the samples at certain particle sizes for the Bill Placer and White Caps Dumps samples due to the variety of sizes in the samples. For the Bill Placer, two different particle sizes of -50 mesh and +50 mesh were tested. The White Caps Dumps were split into -35 mesh and +35 mesh sizes to implement the test. The first tests done on the samples were based on a 25% pulp density and 6 hour leach residence time with intermediate samples taken in the first and third hour. The initial tests were done on the Bill Placer -50 mesh and +50 mesh. Recoveries were 75.16 % and 80.86%, respectively. Residue grades and 24h solution grades were verified by ALS and Met -Solve labs, respectively. Head grades (Calc. Head) are achieved by the sum of residue grades and effective grades at the end of the leach time (24th hour). Residues were assayed by ALS. Whitecaps dump samples vary due to the variety of sizes in the samples. Coronet and EnviroLeach Technologies Inc. subsequently proceeded towards a second round of test work, adjusting the x-leach formula and the results have either confirmed or improved upon the results from the first phase of testing. Given these grades and recoveries, the two companies decided to enter into a formal agreement to further investigate the economic potential of processing of the material. The JV will first build a small scale 50kg pilot plant to determine recoverability and reusability of the formula, gold recovery from solution, optimization and preliminary economics. Following a successful small scale pilot plant test, a 1 tonne per day pilot plant will be built to test 40 tonnes of material to confirm scalability, recoveries and economics.
