Rambler Metals and Mining plc provided a further update to its 2022 underground diamond drilling program at the Ming Copper-Gold Mine, Baie Verte, Newfoundland and Labrador, Canada released on 23 August 2022. This is the first release of all data presented in this announcement; gold assays are not available at time of release and will be updated as they become available. Rambler has drilled over 12,767 meters year to date in 2022.

The 2022 program is providing definition and exploration drilling throughout the mine, focusing on near term production stopes, and step-out drilling from known mineralization proximal to mine infrastructure. Targets have included Ming North Zone ("MNZ"), Lower Footwall Zone ("LFZ"), the Upper Footwall Zone ("UFZ"), the LP East Zone ("LPEZ"), and the Jennings Zone ("JZ"), and the Ezekiel Zone ("EZZ"). This announcement focusses on a small but highly significant part of the drilling program conducted with the small (57mm) diameter short hole Termite Drill which is a smaller and more mobile drill designed to drill short holes quickly.

Total drilling reported in this release includes 161.00 metres in 8 holes. All of the holes in this release were drilled to test the extent of mineralisation around the 760L of the mine, particularly proximal to the LFZ stoping areas planned for the level. The drill program has focussed on Drift 4 (of 4) on the 760L and has added 34,000 tonnes of ore at 2.13% Cu representing an additional 82% of ore tonnes that were anticipated from the stopes that the drilling covers.

This is a 13% increase on the total current mineable material planned from the 760 level. Termite drilling will continue as an integral part of mining process and is anticipated to further extend the production life of the 760L. Aside from the benefit of the increased resource, the enhanced proximal information is feeding into optimised stope designs, drill and blast patterns, geotechnical assessment and ground support design.

This improved definition provides greater control of the stoping process, enabling the mine to maximise extraction with minimal dilution and ore loss. Importantly, the Termite Drilling information is improving stope outcomes from development that is already established. This improved stope shape also improves drilling and blasting controls of the stopes and overall dilution control and management.

In addition to contributing to near-term mining operations, as with all drilling data, these results will be incorporated into the resource model and will likely improve the overall grade and tonnage for the Lower Footwall Zone. The drilling program for the Ming Mine is being run under the supervision of Mark Ross, P. Geo., who is a qualified person as defined by NI43-101. All drilling reported in this release was completed by an independent contractor with AQTK-sized diamond core (48 mm diameter).

Rambler employs an Oriented Core tool which provides valuable information in terms of the orientation of mineralized stringers, dip and dip direction of structure, lithology and foliation for future modelling and geotechnical interpretation. Logging and sampling of diamond drill core is completed on site by Rambler geologists who ship samples daily, using Rambler vehicles and drivers, to the Company's own laboratory for copper assay by standard x-ray fluorescence ("XRF") methodology. As part of its QA/QC program 10% of all samples processed are sent for duplicate analysis at an accredited external lab using standard XRF methodologies.

Sample pulps are later shipped, using commercial freight services, to independent laboratories for gold assaying.
