ACTIVITIES REPORT FOR JUNE QUARTER, 2022

______________________________________________________________________________________

Dome Gold Mines Limited ("Dome" or "Company") (ASX code: DME) is pleased to report activities at its industrial sand-magnetite-heavy mineral, its Nadroga copper-gold and Ono Island gold-silver projects in Fiji for the period ended 30 June 2022.

Highlights

• The current 3-year period for the Sigatoka Special Prospecting Licence SPL1495 expired on the 10th of February 2022 and the Company is pleased to report that the SPL1495 licence was renewed for a further 3-year term ending 26th April 2025.
• IHC Mining issued its final report on the pilot plant processing of the representative bulk sample from the Sigatoka deposit. The highlights of the results were that magnetite concentrate contained 59.7% Fe, exceeding the target of >56.5% Fe.
• Samples of magnetite concentrate and washed industrial sand from the pilot plant have been prepared for presentation to potential customers.
• During the June 2022 quarter, engineering, mine planning, marketing, Geotech, marine studies, and EIA consultants have been working diligently on all aspects of the DFS. The completion of the DFS will be a major milestone toward mine development at the Sigatoka Project.
• A Non-disclosure agreement has been entered into with a major international mining group. Site inspections including examination of existing drill core on Ono Island and collection of samples from areas of interest on SPL1451 and SPL1452 were undertaken earlier in July.

SIGATOKA (SPL1495) DFS PROGRESS

The final report on the pilot plant processing of the bulk sample of sand from Sigatoka was issued by IHC Mining in June. The conclusions from the IHC report are as follows;

"… Sigatoka average grade DFS metallurgical test work sample processed readily through the DFS process presented herein. The process was simple, utliised standard mineral sands separation quipment and demonstrated process consistency and robustness.

Ultimately, a Magnetite Product containing 59.7% Fe was produced from the average grade DFS metallurgical test work sample, with an overall mass yield of 11.8%. This represented a target

magnetite/titano-magnetite mineral recovery of 83.2% (QEMSCAN) or 86.9% (magnetic fractionation).

A tailings stream, representing a further 54.6% mass yield, was identified to be suitable for construction sand applications including fine concentrate aggregate, graded asphalt aggregate and unbound pavement.

Additionally, the Dome Gold magnetic fractionation method has again been proven to be an inexpensive, fast and effective method for estimating magnetite/titano magnetite grade and recovery."

3. Mining Package - AMC Consultants Pty Ltd
4. Environmental Impact Assessment - Smith Geosciences Consultancy
5. Marketing Studies - Stratum Resources
6. Marine Studies - Royal Hosking DHV
7. Financial Model - Flagstaff PCM Pty Ltd

Work on all of the DFS packages is progressing well including several new areas of investigation now required by the Fiji Government.
