• 51% and 49% from diluted vein and historical dump + other, respectively
• 507 tonnes per day ("tpd") milled at 82% availability
• 92.7% gold recoveries
• 138,602 tonnes in stockpile containing 12,832 oz Au at a blended grade of 2.88 g/t Au
• 10,291 oz Au recovered and 9,588 oz Au sold at an average realized price of US$1,797 per ounce

Akiba Leisman, Chief Executive Officer of Mako states that, "this quarter was the second full quarter of commercial production at San Albino. The mine is performing well and the mill has been debottlenecked. The mill has now averaged nameplate capacity of over 500 tonnes per day for the quarter, which is a 15% improvement over the previous quarter including mill availability (38,313 tonnes milled in Q4 vs. 33,441 total tonnes milled in Q3). Replenishment of spare parts and minor adjustments to the plant are expected to further improve mill availability for the first quarter of 2022 and beyond. Over 10,000 ounces were recovered in Q4 2021, with 9,588 ounces sold during the quarter and the balance sold early in January. Operating cash flow from the mine is robust, with exploration expenditures increasing, payables now fully normalized from elevated levels during ramp-up, and approximately US$4.5 million of principal being repaid since the end of Q3."

Mining

The mine averaged 480 tpd of diluted vein material and historical dump + other in Q4 2021 with a strip ratio of 16.5 (see Table 1).  The stockpile is now 138,602 tonnes and is comprised of 6,510 tonnes of diluted vein material at 13.62 g/t Au and 132,092 tonnes of historical dump + other at 2.35 g/t Au for a total of 12,832 oz Au (see Table 2). 

Since the end of September, most of the diluted vein material has been coming from the Porcelana Zone, which is being blended with historical dump + other at the mill. The Porcelana Zone, which has the highest grade-thickness profile encountered at San Albino, is expected to make up the majority of the diluted vein tonnes for the foreseeable future.

Reconciliation to the mineral resource estimate prepared by Mine Development Associates, a division of RESPEC, out of Reno, Nevada has been excellent, with a 10% and 2.5% positive reconciliation to grade and ounces, respectively. A detailed mine reconciliation update was recently released (see press release dated January 11^th, 2022).  A technical report for the updated mineral resource estimate was filed in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects ("NI 43-101") under the Company's SEDAR profile at ww.sedar.com and is also available on the Company's website at www.makominingcorp.com (see press release dated October 19, 2020).

Milling

All components of the 500 tpd gravity and carbon-in-leach processing plant have been fully operational since the beginning of May 2021. During Q4, 2021, the plant has been averaging 507 tpd at 82% availability (see Table 1). Since this time, the plant has been processing 51% diluted vein material and 49% historical dump + other to achieve an average blended grade of 9.01 g/t Au and recovering an average of 92.7% (see Table 1). Throughput was impacted by greater than expected downtime issues with the tailings management system in November, which has since been resolved.

Better control of the process water, as a result of adjustments to the filter press and pumps, has allowed the Knelson concentrator to run properly and operate more hours. The gravity circuit is now operating continuously, and is expected to improve recoveries relative to material type (i.e. oxide, fresh and dump material), and reduce processing costs of the high-grade mineralization coming from the Porcelana Zone.

An additional carbon stripping vessel is being fabricated to increase stripping capacity in the elution circuit, which is expected to be operational in Q2 2022.  Wood from historical timbering has impacted stripping efficiency as wood often gets trapped in screens throughout the plant.  Procedures implemented at the mine have been very effective to deal with the wood, but an additional stripping vessel is expected to fully debottleneck this part of the plant.

All of the above mentioned improvements to the processing plant have helped the plant achieve processing rates of an average of 507 tpd in Q4 2021, with over 10,000 ounces of gold recovered (see Table 1).
