Giyani Receives Positive Leaching Results

Giyani Metals Corp. May 6, 2019 (TSXV:EMM) (FRANKFURT:KT9) (WKN:A2DUU8) (“Giyani” or the “Company”) is pleased to announce the first results from its phase-two hydrometallurgical test program that covers all three components of purification starting with leaching, through solvent extraction, and finishing with electrowinning. Last year Giyani completed phase-one hydrometallurgical testing which only included the leaching of manganese mineralized material from its K.Hill deposit in Botswana. As part of the phase-two program, these leach tests had to be repeated to provide enough material for the subsequent solvent extraction tests. These repeated tests have confirmed and improved the results from last year.

Leaching is the first, and most critical, phase in a three-step purification process that is designed to produce high purity electrolytic manganese metal (EMM). The second step, solvent extraction, is currently in progress and will be followed shortly by the third and final step, electrowinning.

Two main samples were tested MT10 and MT11. MT10 was assayed at 24.7% Mn and MT11 was assayed at 30.72% Mn. A series of leach tests were performed on the two samples to determine the leaching response of manganese with time. The leaching test results show that manganese recovery was approximately 94% with most of the recovery occurring within the first hour of residence time.

A summary of the manganese recoveries is shown in Table 1 below.

Robin Birchall, CEO of Giyani commented:

“We are very pleased with the leaching results as they reflect a much higher recovery at 94% compared to the lower and more conservative 60% that was used for our maiden mineral resource estimate announced back in September 2018. These improved test results not only bode well for further hydrometallurgical tests but will also, ultimately, result in a lower cut-off grade for our K.Hill resource with the obvious corresponding impacts on the resource size.”   

The leaching tests were performed on samples collected from drill cores extracted during the Company’s drilling program in the summer of 2018. The cores were from a hole that was specifically drilled for hydrometallurgical testing and is deemed representative of the K.Hill deposit. The samples were ground to a d80 of 200 micrometers (where 80 percent of the product is finer than 200 micrometers).  From this, ten sub-samples were drawn of 25g.  One sub-sample was set aside and assayed later as the head grade. Four sub-samples were used for reductant tests and five for non-reductant tests. All tests were performed using 25g of rock sample, 125 ml of 3.64M H2SO4 solution at 90C. Four independent leaches were performed with the reductant with only residence time being varied: 30, 60,120 and 180 minutes.  Five independent leaches were performed without the reductant with only residence time being varied: 15, 30, 60 120 and 180 minutes.  All ten sub-samples were assayed for manganese.
