SILVERCORP ANNOUNCES NON-BINDING TERM SHEET FOR PROPOSED ACQUISITION OF CELSIUS RESOURCES LIMITED

Silvercorp Metals Inc. has signed a non-binding term sheet with Celsius Resources Ltd. regarding a proposed transaction pursuant to which Silvercorp will acquire all of the issued and outstanding shares of Celsius. The addition of Celsius's advanced-stage Maalinao-Caigutan-Biyog copper-gold project (MCB project) in the Philippines to Silvercorp's profitable underground silver mining operations will move Silvercorp into being a diversified precious-base metals producer.

The major terms of the proposed transaction are:

1. Silvercorp has offered to acquire all of the outstanding shares of Celsius from the shareholders of Celsius, at a fixed price of three Australian cents per share, in exchange for consideration comprising 90 per cent Silvercorp shares plus 10 per cent in cash. Silvercorp's share price will be determined based on the volume-weighted average trading price on the New York Stock Exchange for the 20 business days ending on the scheme record date.
2. The consideration of three Australian cents per share represents a 76-per-cent premium to the 20-day volume-weighted average price of Celsius as of the close of trading on the Australian Securities Exchange (ASX) on May 11, 2023. The total consideration is approximately $56-million (Australian). Using Silvercorp's current share price, the proposed transaction will result in Silvercorp issuing approximately 9.7 million shares and paying $5.6-million (U.S.) the shareholders of Celsius.
3. Celsius and Silvercorp have also executed a private placement subscription agreement at 1.5 Australian cents per Celsius share for a total of $5-million (Australian). This will provide interim financning for further development of Celsius's MCB project. On closing of the private placement, Silvercorp will own approximately 15 per cent of the outstanding shares of Celsius.
4. In addition to the consideration, Celsius shareholders will receive shares in a new exploration company (Spinco) which will hold all of Celsius's rights and interests with respect to the Sagay (Philippines) and Opuwo (Namibia) projects. The Spinco shares will be distributed on the basis of 10 Celsius shares for one Spinco share. Spinco will seek a listing on the ASX or London Stock Exchange Alternative Investment Market (AIM) through a demerger and concurrent initial public offering. Silvercorp has agreed to invest $4-million (Australian) in Spinco, valued at a postfinanced market capitalization of $30-million (Australian).
5. The proposed transaction will be implemented by way of a scheme of arrangement or other appropriate form of transaction under Australian laws, under a definitive agreement to be negotiated and entered into by Silvercorp and Celsius within one month of the term sheet. The final structure of the proposed transaction will be governed by the terms of the definitive agreement. The term sheet does not create a binding agreement with Celsius for the proposed transaction, and there is no assurance that Silvercorp and Celsius will reach agreement on the terms of the definitive agreement as set out in the term sheet, or at all. If the proposed transaction is not completed, Silvercorp will have the right to maintain its percentage interest in Celsius pursuant to the placement agreement. In addition to entering into the definitive agreement, completion of the proposed transaction is subject to, among other conditions, satisfactory completion of due diligence, voting support of key Celsius shareholders, Celsius shareholder approval and regulatory approvals.

Dr. Rui Feng, chairman and chief executive officer of Silvercorp, commented:

"The addition of the MCB project to our growing project portfolio aligns with our strategic objectives of diversifying and growing our asset base and will position us to benefit from copper's strong fundamentals, a key ingredient in the green energy revolution. We believe this is a rare opportunity to leverage our underground mining expertise and financial strength to unlock value for all shareholders through the development of the MCB project, as well as aggressive exploration programs in the Pacific Rim metallogenic belt, one of the most important porphyry copper-gold belts in the world.

"We look forward to partnering with the government of the Philippines to make a successful entry into the region, leveraging Celsius's well-established team and strong local relationships to ensure a smooth transition and continued development that benefits all stakeholders."

Transaction rationale for Silvercorp:

• Greater diversification: The acquisition of Celsius's MCB project gives Silvercorp exposure to a high-grade copper-gold project well suited to its extensive underground mining experience, in a promising jurisdiction with substantial local relationships and support, and together with Silvercorp's continuing acquisition strategy, provides the opportunity for a significant rerate upon successful development of the MCB project.
• Enhanced strategic positioning: The MCB project provides significant exposure to copper and aligns with Silvercorp's strategy of being a responsible supplier of strategic metals for the expanding green energy sector.
• Exploration upside: Silvercorp's substantial free cash enables financing exploration programs to test numerous, high-priority brownfield and greenfield exploration targets within a land package covering 27.2 square kilometres of the highly prospective (and productive) MCB project area.
• Significant pro forma synergies: The acquisition of Celsius will combine Silvercorp's strong management and underground mining skill set with Celsius's deep experience and network in the Philippines to ensure near-term development of the MCB project.
• Strong financial position: Through a share and cash transaction, Silvercorp can preserve its cash reserves while minimizing dilution. As a result, the company's strong financial position, supported by its robust cash flow profile, will provide ample financing to optimize and develop the MCB project, as well as pursue additional merger and acquisition opportunities.

The MCB project

Based on Celsius's publicly released information, the MCB project is located in the Cordillera Administrative Region of the Philippines, approximately 320 km north of Manila. Porphyry-style mineralization in the MCB project area was first discovered in the early 1930s, but modern exploration was limited until Freeport McMoRan entered in 2006. Over the next seven years, Freeport conducted systematic exploration work and completed approximately 25,500 metres of drilling in 46 diamond drill holes. Celsius entered an agreement to acquire the MCB project in September, 2020, and has since drilled nine more diamond holes, bringing the total number of drill holes to 55.

A maiden JORC compliant mineral resource estimate (MRE) was released for the MCB project in January, 2021, reporting 290.3 million tonnes of indicated resources grading 0.48 per cent copper and 0.15 gram per tonne gold, and 23.5 million tonnes of inferred resources grading 0.48 per cent copper and 0.10 g/t gold.

An updated JORC compliant MRE was announced in December, 2022, reporting 296 million tonnes of measured and indicated resources grading 0.46 per cent copper and 0.12 g/t gold, containing 1.36 million tonnes of copper and 1,146,000 ounces of gold, and 42 million tonnes of inferred resources grading 0.52 per cent copper and 0.11 g/t gold, containing 218,000 tonnes of copper and 149,000 oz of gold.

A scoping study for the MCB project was released by Celsius in December, 2021, which outlined a development plan for an underground mining operation with backfilling and a flotation mill at 2.28 million tonnes per year to produce high-quality copper-gold concentrates for a 25-year mine life. The estimated average head grade is 1.18 per cent copper and 0.56 g/t gold with a 94-per-cent recovery rate for copper and 79 per cent for gold, producing 22,000 tonnes of copper and 27,000 oz of gold annually for the first 10 years.

Assuming a copper price of $4 (U.S.)/pound, a gold price of $1,695 (U.S.)/oz and an estimated initial capital expenditure of $253-million (U.S.), the scoping study concluded that the MCB project has a posttax net present value (8 per cent) of $464-million (U.S.), an internal rate of return of 31 per cent and a payback period of approximately 2.7 years.

Significant MCB permitting progress

A memorandum of agreement (MOA) was signed with the local communities and the National Commission on Indigenous Peoples (NCIP) in November, 2022, which allows the development and operation of the MCB project for 25 years, renewable for another 25 years. With the endorsement of local communities and an environmental compliance certificate issued by the Philippine government, Celsius is in the final stage of obtaining the mining permit from the Philippine government, the mining production sharing agreement (MPSA), necessary for the development of the MCB project.
