Acquisition and Financing Terms

Summit acquired the Portfolio comprising seven royalties and one stream from IAMGOLD through a purchase and sale agreement for total consideration of $17.5 million comprising cash consideration of $10 million and common shares of Summit valued at $7.5 million.

To satisfy the $10 million of cash consideration, Summit successfully raised over $13 million through a non-brokered private placement comprised of leading institutions and sophisticated retail investors.

Bomboré Mine (50% Silver Stream)

The Bomboré mine is located in Ganzourgou Province, Burkina Faso, 85 km east of the capital city of Ouagadougou and is accessible via a paved highway. Constructed on-time and under budget by Orezone Gold Corporation (TSX:ORE), Bomboré achieved commercial production of its Phase I oxide plant on December 1, 2022, and has successfully operated above its planned nameplate capacity.

In 2024, Bomboré produced approximately 119 Koz of gold at an all-in sustaining cost of under $1,450/oz sold. Orezone currently has a Proven and Probable reserve estimate at Bomboré of 2.4 Moz at 0.73 g/t gold, a Measured and Indicated resource estimate of 4.5 Moz at 0.78 g/t gold and an Inferred resource estimate of 0.6 Moz at 0.95 g/t gold.

Orezone is currently constructing a parallel 2.5 Mtpa hard rock plant, which will increase production to over 170 Koz annually, commencing in Q4 2025. Construction is fully-funded and remains ahead of schedule and on budget. A secondary hard rock expansion, adding another 2.5 Mtpa processing capacity and increasing gold production to 220 – 250 Koz/year, is being evaluated for acceleration with commissioning in late 2026.

Summit holds a 50% stream on payable silver production at Bomboré, subject to a minimum guaranteed delivery of 37.5 Koz of silver per annum. There are no ongoing payments on the stream, and if the minimum guaranteed delivery is not satisfied, Orezone will accrue the shortfall and make the payment in full five years following the initial silver delivery which occurred in December 2022. The accrual shortfall balance payable to Summit was ~58,000 ounces of silver as at the end of Q1 2025.

If, prior to the fifth anniversary of the date of the commencement of commercial production, Orezone constructs a sulphide processing plant that is capable of processing 3.3 Mtpa, Orezone will have a right to buy back 50% of the stream for $7.15M.

Onças de Pitangui Project ($80/oz for first 250 Koz of gold sold and 1.5% NSR thereafter)

The Onças de Pitangui Project is located in the state of Minas Gerais in Brazil and is owned and operated by Jaguar Mining Inc. (TSX:JAG). Pitangui is located 20 km east of the Turmalina Mining Complex and contains the São Sebastião gold deposit.

Jaguar acquired MTL in September 2004 which has been in continuous operation since it commenced mining in late 2006. Jaguar completed the acquisition of Pitangui from IAMGOLD in September 2023 and released a technical report with an integrated mine plan for the deposit within MTL on March 31, 2025. The technical report outlines a detailed nine-year mine plan with development at Pitangui scheduled to commence in 2026, ramping up to full production in 2027 and averaging ~40 Koz of gold for at least six years.

Jaguar currently has a Proven and Probable reserve estimate at Pitangui of 284 Koz at 4.16 g/t gold, a Measured and Indicated resource estimate of 457 Koz at 4.01 g/t gold and an Inferred resource estimate of 490 Koz at 3.64 g/t gold.

Summit owns an $80/oz production royalty on the first 250 Koz of gold sold, and a 1.5% NSR royalty thereafter on Pitangui.

Zancudo Mine (0.5% NSR royalty)

The Zancudo Mine is located in Antioquia, Colombia and owned and operated by Denarius Metals Corp. (CBOE: DMET).

Denarius recently commenced mining operations at Zancudo, with first production expected in Q2 2025. According to a Preliminary Economic Assessment (“PEA“) completed for Denarius in October 2023, Zancudo is expected to produce over 575 Koz of payable gold and over 8.8 Moz of payable silver over a 10.3 year mine life. Economics indicated by the PEA were favourable, generating an after-tax IRR of 287% using long-term prices of $1,800/oz gold and $22/oz silver.

Denarius currently has an Inferred resource estimate at Zancudo of 860 Koz of gold at 6.53 g/t and 14.1 Moz of silver at 107 g/t.

Summit owns a 0.5% NSR royalty on Zancudo.
