GEMFIELDS ACHIEVES STRONG RESULTS AT SEPTEMBER 2024 COMMERCIAL-QUALITY AUCTION

Highlights – MRM Commercial-Quality Auction – September 2024

• Auction revenues of USD 2.3 million
• All of the 5.7 million carats (1,130 kilograms) offered in 10 lots were sold (100%)
• The average sales price of USD 0.41 per carat

Adrian Banks, Gemfields’ Managing Director of Product & Sales, commented:

“We extend our gratitude to the auction participants who made this brief, three-day auction such an enjoyable event. The majority of the auction’s offerings consisted of corundum and sapphire, which are considered by-products of MRM. Despite the commercial nature of these goods, the auction saw strong attendance and robust demand. The significant volumes of the lower-priced rough sold will support the cutting factories in both Chanthaburi, Thailand and Jaipur, India. We thank and congratulate the Government of Mozambique and our partners at Mwiriti – both of whom attended the auction – on what are very healthy results for material of this quality.”

Gemstones Extraction by Montepuez Ruby Mining Limitada (MRM)

The gemstones were extracted by Montepuez Ruby Mining Limitada in Mozambique (“MRM”, which is 75% owned by Gemfields and 25% by Mwiriti Limitada). The proceeds of this auction will be fully repatriated to MRM in Mozambique, with all royalties due to the Government of the Republic of Mozambique being paid on the full sales prices achieved at the auction.
