Operational Update

Production and Developed State

· The developed state of the underground mine has now been brought to a position where full production of 1,350 tonnes per day (“tpd”) through the processing plant is imminent. The status of the four main production areas in the mine are as follows:

o 510L LFZ: Production activities and diamond drilling continue in this area.

o 770L and 790L UFZ: Production activities continue in this area.

o 785 Ming North Zone: Development as a cut and fill operation continues through the zone at scheduled rates. Diamond drilling to infill the zone down plunge was completed and reported on 28 April 2022.

o 735L and 760L LFZ: Production activities continue in this area.

The grade was lower than initially planned in April due to mining out of planned sequence to install additional ground support in the Upper Footwall Zone. Grade is expected to pick up in May.

Nugget Pond

The Nugget Pond processing plant achieved throughput averaging over 1,000 dmt per day despite a maintenance issue with the secondary crusher which caused the mill to operate at or below 800 dmt for 9 days of the month. The Company rented a crushing plant from a local supplier and was able to achieve these rates of throughput, all the while building a 22,500 dmt stockpile of ore in front of the plant. The arrangement with the rented crusher has continued into May and is expected to do so until mid-month.

Covid-19 Update:

All provincial restrictions have been lifted as of March 14, 2022. Rambler will continue to abide by all Public Health guidelines for the long-term management of Covid-19 and protection of the entire workforce.

Toby Bradbury, President and CEO, commented:

“Focus for us has been to fully utilise the capacity of the mill at Nugget Pond and our peak daily plant throughput during April was 1,408 dry metric tonnes. Our mining is now at a rate that can support the designed plant throughput, and we will now optimise the feed grade to the mill. We have built a valuable stockpile ahead of the mill which mitigates some of the mining risk that the operation has been exposed to over recent years and we continue to progressively build resilience into all aspects of the operation.”
