MAKO MINING ANNOUNCES OPERATIONAL UPDATE ON RECOVERIES
Mako Mining Corp. reported operational updates on October 3, 2022, revealing Q2 2022 recoveries at 74.5%, lower than the 86% from 2019 tests. Post improvements initiated on August 10, recoveries averaged 85.9%. Key upgrades included reducing preg-robbing materials and optimizing mill throughput and cyanide levels. Despite lower recoveries, Mako generated $7.5 million in Mine Operating Cash Flow for Q2 2022, allowing $2.7 million for growth exploration. Future improvements include resuming pre-leach thickener operations to enhance efficiency.
- Achieved average recoveries of 85.9% post improvements.
- Generated $7.5 million in Mine Operating Cash Flow for Q2 2022.
- Invested $2.7 million in growth exploration.
- Q2 2022 recoveries were below expectations at 74.5%.
VANCOUVER B.C, Oct. 3, 2022 /PRNewswire/ - Mako Mining Corp. (TSXV: MKO) (OTCQX: MAKOF) ("Mako" or the "Company") is pleased to provide the following operational and corporate updates:
On July 20, 2022 the Company announced Q2 2022 production results showing recoveries of
*Preliminary results based on information obtained through September 30th, 2022 |
The improvements implemented are listed below:
- Through selective mining procedures and blending protocols, the amount of preg-robbing material going through the mill was significantly reduced. The hanging wall and foot wall appears to have a much higher preg-robbing potential than the vein and weathered lithologies and our selective mining procedures were able to separate this material effectively
- The mill throughput was reduced from 544 tpd in July to 449 tpd in September in order to increase the leach retention time
- The lower mill throughput also resulted in a grind size improvement from
77.2% passing 75 microns to79.1% passing 75 microns - The measured free cyanide in the grinding circuit fell from 14.1 ppm to 2.1 ppm through improved operational procedures. The lower cyanide levels in the grinding circuit contributed to reduced losses through preg-robbing
- The inventory of carbon in the CIL circuit was increased from 25 to 34 tonnes
Further improvements anticipated in the coming months include:
- Resuming operation of the pre-leach thickener which will allow for a higher slurry density in the CIL, allowing for an increased throughput rate without sacrificing leach retention time
- Replacement of worn-out carbon retention screens to improve carbon loading efficiencies
Akiba Leisman, CEO of Mako states that "the transition to carbonaceous fresh material from the oxide zone that we were mining in 2021 was a significant challenge for us to overcome. Nonetheless, our team's quick and diligent response through a series of testing and improvements allowed us to get back to
The Company has included reference to Q2 2022 Mine Operating Cash Flow which is a non-GAAP financial measure. This non-GAAP measure is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. In the gold mining industry, this is a commonly used performance measure, but does not have any standardized meaning prescribed under IFRS and therefore may not be comparable to other issuers. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company's underlying performance of its core operations and its ability to generate cash flow.
Mine Operating Cash Flow represents operating cash flow, excluding Nicaraguan taxes and royalties, changes in non-cash working capital and exploration expenses.
