Mergers & Acquisitions Royalties & Streams

SUMMIT ROYALTIES TO COMBINE WITH STAR ROYALTIES TO CREATE A

SCALED, HIGH-GROWTH ROYALTY PLATFORM

Toronto, Ontario, March 16, 2026 – Summit Royalties Ltd. (TSXV: SUM, OTC QB: SUMMF) (the "Company"

or "Summit") and Star Royalties Ltd. (TSXV: STRR, OTCQX: STRFF) ("Star") are pleased to announce that they

have entered into an arrangement agreement (the "Agreement") pursuant to which, among other things,

Summit has agreed to acquire all of the issued and outstanding common shares of Star by way of a court

approved Plan of Arrangement under the Canada Business Corporations Act (the "Transaction").

Assuming completion of the Transaction, holders ("Star Shareholders") of common shares of Star ("Star

Shares") are entitled to receive 0.360 (the "Exchange Ratio") of a common share of Summit (each a

"Summit Share ") in exchange for each Star Share held immediately prior to the effective time of the

Transaction (the "Consideration"). Upon completion of the Transaction, existing holders of Summit Shares

and Star Shareholders are expected to own approximately 72% and 28%, respectively, of the pro forma

company on a fully-diluted in-the-money basis.

The Consideration implies a value of C$0.60 per Star Share based on the Exchange Ratio and the closing

price of the Summit Shares on the TSX Venture Exchange ( "TSXV") on March 13, 2026, representing a

premium of approximately 25% to the closing price of Star Shares on the TSXV on the same date. Based

on the 20-day volume weighted average prices ("VWAP") of the Summit Shares and the Star Shares on the

TSXV for the period ending March 13, 2026, the Consideration implies a premium of approximately 32% to

Star Shareholders. The implied fully-diluted in-the-money equity value of the Transaction is approximately

C$51 million.

Transaction Highlights and Strategic Rationale

• Immediate Scale & Quality

o 50 royalties and streams across 3 core jurisdictions being Canada, USA, and Australia;

o ~63% of net asset value (" NAV") from assets in production or with committed timeline s to

production; and

o Diversified revenue base with 4 assets currently in production, expected to increase to 6 by

2027.

• Industry-Leading GEOs Growth

o ~47% GEOs CAGR expected over the next 3 years, which would be the highest among junior

royalty and streaming companies based on analyst consensus estimates;

o Visibility driven by existing development assets and growth from material assets with

committed timelines to production; and

o Additional upside from identified pipeline and from disciplined future acquisitions.

• Accretive & Cash Flow Enhancing

o ~US$2M of identified annual cost synergies through the elimination of duplicate public

company costs, personnel changes, and operational changes;

o Copperstone and Pitangui expected to be in production by 2027, increasing estimated 2027

revenue to over US$15M at consensus metal prices; and

2

o Small, agile team with minimal G&A funnels cash flow back into the business .

• Meaningful Re-Rate Potential

o ~C$184M expected pro forma fully-diluted in-the-money market capitalization;

o Improved capital markets presence and trading liquidity, with supportive shareholder base;

and

o Pro forma Summit valued at a significant discount to peers on Price /NAV and Price/2027E

cash flow per share ("CFPS") basis.

Drew Clark, President, CEO & Director of Summit , commented: " We are very excited about the

transformative combination of Summit and Star, which results in an expanded portfolio of cash -flowing

assets underpinned by a peer-leading growth profile. The addition of the Copperstone gold stream to our

existing portfolio is expected to drive material cash flow growth in the coming years, further enhancing

our ability to sustain our high -growth trajectory. With this T ransaction, Summit has scaled from zero to

50 assets in less than a year, and we are eager to continue building on this momentum through

disciplined, accretive growth for the benefit of our shareholders."

Alex Pernin, CEO & Director of Star, further commented: "We are proud to announce this transformative

business combination as we believe this merger will represent one of the most compelling investment

opportunities available in the royalty sector. Our combined business will be underpinned by improved

scale, industry-leading revenue growth, meaningful portfolio diversification, enhanced trading liquidity

and institutional investor appeal , and a n improved free cash flow profile . We would like to thank our

shareholders for their support to date , and we look forward to our upcoming re-rating potential,

especially g iven our attractive pro forma valuation metrics and the significant number of near-term

catalysts expected across our combined portfolio."

commencement of construction later in the year; and

• Enhanced Tier-1 jurisdictional exposure.

Benefits for Star Shareholders

• Immediate premium of 25% based on spot prices and 32% based on 20-day VWAPs of Summit and

Star;

Cornerstone Assets to Drive Growth

Bomboré (50% Silver Stream)

The Bomboré mine ("Bomboré") 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) ("Orezone"), Bomboré achieved commercial production of its Phase

I oxide plant on December 1, 2022, and has successfully operated above its planned nameplate capacity.

In 2025, Bomboré produced approximately 11 0 Koz of gold. 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 recently constructed and successfully commissioned a parallel 2.5 Mtpa hard rock plant, which is

expected to increase production to over 170 Koz annually in 2026, commencing in Q4 2025. Commercial

production at the hard rock plant was completed on January 15, 2026. A secondary hard rock expansion,

expected to add another 2.5 Mtpa processing capacity and increase gold production to 220 – 250 Koz/year,

is being evaluated for acceleration with expected 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.

Madsen (1% NSR Royalty)

Madsen is an underground gold mine located in Red Lake, Ontario, owned and operated by West Red

Lake Gold Mines Ltd (TSXV: WRLG) ("West Red Lake"). West Red Lake declared commercial production on

January 12, 2026. A joint Madsen and Rowan PFS is expected to be released in Q3 2026 that will outline an

expanded mining operation for both assets.

West Red Lake currently has a Proven and Probable reserve estimate at Madsen of 478 Koz at 8.16 g/t gold,

an Indicated resource estimate of 1,653 Koz at 7.4 g/t gold and an Inferred resource estimate of 366 Koz at

6.3 g/t gold. Historically, Madsen produced 2.5 Moz Au at 9.7 g/t Au between 1938 to 1976 and 1997 to 1999.

Summit has a 1% NSR royalty on the 4,700 ha Madsen property.

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

The Onças de Pitangui Project ("Pitangui") is located in the state of Minas Gerais in Brazil and is owned and

operated by Jaguar Mining Inc. (TSX:JAG) (" Jaguar"). Pitangui is located 20 km east of the operating

Turmalina Mining Complex ("MTL") 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

4

technical report outlines a detailed nine -year mine plan with development at Pitangui scheduled to

commence in 2026, ramping up 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.

Copperstone (4% Gold Stream)

The Copperstone project ("Copperstone") is located in Arizona, USA , near the border of California.

Copperstone is a past producing mine that produced 500 Koz from an open pit between 1987 – 1993, and

has substantial infrastructure located at site, including two underground portals and 4,000 m of

underground development work. Owned by Minera Alamos Inc. (TSXV: MAI) ("Minera Alamos"), an updated

PFS on Copperstone is expected to be released in April 2026 with first production expected to occur in Q1

2027.

Minera Alamos has indicated that it intends to release a maiden open pit resource in H2 2026 which could

materially increase the scope and life -of-mine at Copperstone. Additionally, there are numerous

opportunities to expand the underground resource as the ore body extends down-plunge along the open

extensions of two mineralized zones which have been untested in past drilling.

Copperstone currently has a Measured and Indicated resource estimate of 300 Koz at 7.74 g/t gold with

an additional Inferred resource of 197 Koz at 6.3 g/t gold. Based on a 2025 PEA (as defined below) ,

Copperstone is expected to produce an average of 42 Koz per annum over a 6 year mine -life.

Summit will hold a 4% stream on recovered gold production at Copperstone with a 25% ongoing payment.

There are no stepdowns or buybacks on the stream, and the stream covers the entire 3,700 ha project

footprint.

and board of di rectors, as of the date hereof, the Transaction will be completed on terms and timing

currently contemplated, all conditions to the completion of the Transaction will be satisfied or waived

properties in a manner consistent with past practice; the accuracy of public statements and disclosures

made by the owners or operators of such underlying properties; and the accuracy of publicly disclosed

expectations for the development of underlying properties that are not yet in production . Summit and

Star caution that the foregoing list of material factors and assumptions is not exhaustive. Many of these

assumptions are based on factors and events that are not within the control of Summit or Star, and there

is no assurance that they will prove correct. Forward‐looking statements also involve significant known

and unknown risks and uncertainties. Many factors could cause ac tual results, performance or

achievement to be materially different from any future forward‐looking statements. Factors that may

cause such differences include, but are not limited to, changes to general economic, market and business

conditions; Summit and Star's future financial and operating performance; the ability of Summit and Star

to complete the Transaction; Summit's and Star's ability to provide a return on investment; Summit's and

that other events will not intervene to delay or result in the failure to complete the Transaction. There is a

risk that some or all the expected benefits of the Transaction may fail to materialize or may not occur

within the time periods anticipated by Summit and Star. Material risks that could cause actual results to

differ from forward‐looking statements also include the inherent uncertainty associated with the

financial and other projections; the prompt and effective integration of the combined company; the

ability to achieve the anticipated synergies and value‐creation contemplated by the Transaction; the risk

associated with Summit's and Star's ability to obtain the approvals required to consummate the

Transaction and the timing of the closing of the Transaction, including the risk that the conditions to the

Transaction are not satisfied on a timely basis or at all; the risk that a consent or authorization that may

be required for the Transaction is not obtained or is obtained subject to conditions that are not

anticipated; the outcome of any legal proceedings that may be instituted against the parties and others

related to the Agreement; unanticipated difficulties or expenditures relating to the Transaction, the

response of business partners and retention as a result of the announcement and pendency of the

Transaction; risks relating to the value of Summit Shares to be issued in connection with the Transaction;

the im pact of competitive responses to the announcement of the Transaction; and the diversion of

management time on transaction‐related issues. Consequently, there can be no assurance that the

actual results or developments anticipated by Summit and Star (including the Transaction and impact

or benefits related thereto) will be realized or, even if substantially realized, that they will have the

expected consequences for, or effects on, Summit, Star, their respective shareholders, or the future results
