Silvercorp Announces Project Update for El Domo
VANCOUVER, British Columbia – February 4 , 2026 – Silvercorp Metals Inc. (“Silvercorp” or the “Company”) (TSX/NYSE
American: SVM) (the “Company”) announces an update for its budget and construction schedule for the construction of the
El Domo Project (the “Project”).
The construction budget for the Project has been updated to $284 million, an increase of $44 million compared to the $240
million estimate dated March 31, 2025 (for reference, the 2021 Feasibility Study Budget was $248 million). The main items of
increase or decrease are as follows:
1. The VAT: rate has been revised from 10% ($19 million) to 15% ($35 million), resulting in a $16 million increase, which
represents 36% of total budget growth. The Company expects to recover this VAT as a tax credit in the first year of
operations once concentrate exports commence.
2. Package #1 Construction: $5.1 million increase due to detailed design changes, construction of two rock buttress for waste
dumps (SWD and WRF1) were added.
3. The equipment and material purchases of the process plant have increased by $15 million due to:
a. Some equipment was previously missing in both the April 2025 and 2021 Feasibility Studies, e.g. water recycling
system from Tailing Storage Facility (“ TSF”), SAG mill, regrind mill, bigger flotation cells and thickeners required to
accommodate an increase in sulfur content from 9% (2021 Feasibility Study design) to 25% (current design) (~ $11
million).
b. Logistics costs increased by $4 million (considering 15% of all equipment for sea freight, customs fees, storage, local
transport, insurance, plus ~ 3.5% import tax), which was previously underestimated.
4. The estimated construction and installation of the process plant have increased by $7.2 million based on the actual
construction quotes for the 5000-square-metre ROM ore shack currently under construction.
5. Bypass roads and access roads: $3.3 million increase mainly due to the upgrade of the new southern access road, so that
40-foot container trucks can pass.
6. External powerline: added $2.3 million for payment on behalf of the Ecuador National Power Company (CNEL)for third-
party supervision and land easements.
7. Missing items such as Engineer of Record (“EoR”), and construction quality assurance and control (“QA/QC”) supervision
for TSF construction, site internal power distribution facilities, environment rehabilitation and protection, 4G network
added another $10.1 million.
8. Added $6.6 million in local purchases to support local supply chains and economy.
9. Owner’s Cost has increased from $30 million to $32.5 million, based on the monthly burn rate and additional expenses
(e.g. insurance, services, community and institution al relationship, and security) plus a six-month extension for the
construction period-~$2.5 million increase.
2
10. Package #2 Mining and Stripping: estimated cost has decreased by $4.2 million based on the winning bidder’s unit prices.
11. Achieved savings of $4.7 million across various other projects.
12. Contingency has been reduced from 20% ($32 million) to 8% ($17 million), a reduction of $15 million, reflecting more
accurate estimates for the current budget. The contingency may account for the diesel price increase during construction
(~10% to ~15% increase in unit costs for civil works), and inherent uncertainties as engineering design work continues.

Based on this new budget, the El Domo P roject is scheduled to be in production by July 1st, 2027, representing a six-month
delay from the previous estimate of early-2027.
Progress Achieved in 2025:
2025 has been a productive year, as we focused on construction Package #1: including Site preparation, Roads, Non-contact
Water Channels, TSF, Saprolite Waste Dump (“SWD”), and proceeded with other packages. During the year, we established
a new project construction team, while overcoming an exceptionally heavy and long rainy season that lasted well into June,
working with different communities and government agencies to ensure a sound working environment. Through the hard
work of our local team, CRCC 14 and other contractors, along with the support of communities and government authorities,
the Company made significant progress at the Project.
1. Spent $44.5 million in 2025, representing approximately 16% of the total new budget.
2. Successfully cleared 1,040 of the total 1,109 archaeological units, completing archaeological clearance in full
compliance with permit conditions to start earth-moving activities.
3. Over 2.6 million cubic metres of material were moved (including topsoil, saprolite and andesite material) for site
preparation of Process plant, roads, TSF, SWD, and other site preparation.
3
4. Built 8.1 km of internal haul roads, providing comprehensive access across the site, and upgraded and repaired 23.1
km of external roads, allowing 40-feet haul truck access. Additionally, 2.1 km of non-contact water channels were
excavated as part of a robust water management system.
5. Completed and commissioned the Construction Camp with a capacity of over 600 beds.
6. Blasted at an on-site quarry and from Process plant Site Preparation to generate fresh non-acid generating rock for
roads and the construction of the starter dam of the TSF, plus laid the foundation for a 5000 square metre ROM
Ore Shed, which will serve as a warehouse initially during the construction period.
7. Yantai Jinpeng Mining Machinery Co.,Ltdhas finalized the detailed process flowsheet, equipment selection and cost
estimates for the processing plant construction and equipment. The improved process flowsheet introduced a
standalone sequential flotation of copper-gold into copper concentrates first; all other parts of the flowsheet follow
the previous design. The new metallurgical recovery test results for the sequential flotation of copper -gold into
copper concentrates first show a 5.4% increase in copper recovery and a 6.2% increase in gold recovery, enhancing
the Project's projected economics.
8. Ordered most of the long -lead time major equipment for the process plant and Diesel Power Generator Sets
providing backup power for the entire site ; paid a down payment of $7.2 million towards a total contract price of
$16.9 million.
9. Continuously engaged with different communities and stakeholders for support.
10. Built an effective, integrated construction team, collaborating among team members at the El Domo construction
site, Quito, Vancouver and Beijing.
11. Strong and improving safety culture and management at site, with more than 960,000 hours worked with no major
incidents.
12. Implemented and complied with the Environmental Management Plan during construction activities.
Bidding for the Package #2 - Open Pit Mining and Stripping
After a competitive bidding process and several months of negotiation, the Company is expected to execute the mining
contract for the construction and operation of the Project with China Railway 19th Bureau Group Co., Ltd. (“CRCC 19”) on a
“Unit Cost” basis, that is , the cost of drilling, blasting, hauling and dumping or compacting each cubic metre of rock over a
certain distance. The fixed unit rate contract is structured into two primary phases: 1) the Construction Phase, valued at $35
million for mining and stripping, includes pre -stripping activities such as earthworks, rock stripping, and by -product ore
mining; and 2) the Operations Phase, valued at approximately $63 million over the subsequent five years, covers annual
mining and stripping of ore and waste rock. In addition, the contract includes the construction and management of the multi-
stage raising of the Tailings Storage Facility (TSF) dam ($8 million). CRCC19 has a regional headquarter in Quito with over ten
years operating experience in Ecuador building a large open pit copper -gold mine and ongoing mining and stripping. In
advance of executing the contract CRCC 19 began mobilizing personnel to the El Domo site in January 2026 and equipment
mobilization will begin this month.
Package #3 - Processing plant construction and equipment
Yantai Jinpeng Mining Machinery Co.,Ltd is expected to complete the detailed engineering design of the processing plant
based on the new flowsheet by early April 2026. This will serve as the cost base to initiate the bidding process for construction.
With most equipment already ordered , the primary budget variables for Package #3 would be the construction cost and
materials
Packages #4 - External Powerline and standby diesel generators
4
The total distance of the external powerline is 61.3 km. The northern section (27.5 km) and three substations, with a $10.15
million budget, have been awarded to two Ecuadorian contractors last September , but only recently received the approval
by CNEL required before construction can be started. The southern part (33.8 km) is pending the completion of detail ed
engineering design. The powerline is expected to be completed in 202 7. As a backup plan, the company has ordered 14MW
of diesel generator sets which will be delivered to site by December 2026 for installation . This mitigation plan will ensure
power is available for commissioning of the process plant in July 2027, regardless of the External Powerline status.
