Update on Construction Plan and Schedule

for the Development of the El Domo Project

VANCOUVER, BRITISH COLUMBIA, April 23rd 2025 -- SALAZAR RESOURCES LIMITED (TSXV: SRL,

OTCQX: SRLZF, Frankfurt: CCG.F) (“Salazar” or the " Company") provides an update on El Domo

Construction.

Silvercorp Metals Inc. (“Silvercorp”) and the Company are in a joint venture (“Joint Venture”) for the

development of the El Domo mine with Silvercorp holding a 75% interest and the Company a 25% carried

interest. Silvercorp (TSX/NYSE American: SVM) is operator of the Joint Venture and has been moving

forward with construction of the El Domo mine. Silvercorp has recently provided an update to the

Company on the development plans as the Joint Venture moves to bring El Domo into production.

The Joint Venture is targeting the start of production for the Project by the end of 2026 at an estimated

cost of $240.4 million, compar able to the $247.6 million estimate in the feasibility study (NI 43 -101

Technical Report - Feasibility Study - Curipamba El Domo Project, Central Ecuador) published in 2021

("2021 Feasibility Study").

The Company holds a 25% free carried interest on the Project and, once commercial production is

achieved, Silvercorp will receive 95% of the dividends from the Project until its aggregate investment, has

been recouped minus the approximate Salazar carrying value of US$ 20 million, after which dividends will

be shared on a 75%/25% pro -rata basis with Salazar . The payback time is estimated to be 2.6 years

according to the 2021 Feasibility Study, which is bound to improve with this updated plan and budget.

The Company is thrilled to see the advances in the construction of the Project and is committed to

continue supporting Silvercorp with its local expertise.

As discussed in its January 7, 2025 Press Release, the Joint Venture has been building upon the 2021

Feasibility Study, with work to date focusing on:

1. Advanced Detailed Engineering for: a) Optimized design with Klohn Crippen Berger (KCB) for the

Tailings Storage Facilities (“TSF”), Saprolite Waste Dump (“SWD”), and non -contact water

channels; b) Optimized open pit mine design for mining, stripping, and scheduling, and

coordinated the mining schedule with ongoing tailings dam construction by internal mining

engineers; and c) by Yantai Jinpeng Min ing Machinery Co. Ltd and Yantai Orient Metallurgical

Design and Research Institute Co., Ltd (together “Jinpeng”), a China certified Engineering Design,

Manufacture and Construction Group which has provided design, equipment, and construction

for mining process plants in China and internationally.

2. Advanced Project Infrastructure for: a) Optimized designs for a new public bypass road and

internal operational haul roads; b) Executed a powerline contract with the Ecuadorian state -

owned power company (CNEL EP) including initiating bidding process for contractor selection; and

c) permitting and sourcing for standby diesel power generat ors for the dry season, as climate

change has impacted the power supply situation in Ecuador.

3. Produced Project Materials Balance for: a) Bid Package 1: Construction of temporary camp, TSF

to starter dam phase, SWD, non-contact water channels, internal haul roads, and preparation of

the process plant site and permanent camp site; b) Bid Package 2: Open Pit Mining, stripping and

ongoing ta ilings dam raises using stripped waste rocks; c) Bid Package 3: Construction of the

process plant, tailings discharge and reclaim back water systems, water treatment plants,

permanent camp, and other site infrastructures; d) Bid Package 4 for the construction of the Power

line; and e) Bid Package 5 for the diesel power generators.

Package #2 – Open pit Mining and Stripping

The cost estimates are based on the optimized mine plan, which is based on the 2021 Feasibility Study,

and the initial quotations received from interested contractors on a “Unit Cost” basis, that is the cost of

drilling blasting and removing each cubic metre of rock a certain distance . The Company has not yet

awarded the commercial contract for Package #2. The table below summarizes the estimated schedule

and costs for Package #2.

Package #2 – Open pit Mining and Stripping $7.0 $32.0 $39.0

The Joint Venture expects to commence stripping of the open pit in August 2025, and a total of 5.4 million

cubic metres of sediments and waste rocks will be stripped among this 3.5 million cubic metres of non -

acid generation (NAG) waste rocks will be stripped and used to build the starter dam and Stage 2 dam of

the TSF, and 43,000 tonnes of ore to be produced by the end of 2026. With this stripping of waste rocks,

ore in pit, ready to be mined, is expected to be 550,000 cubic metres to support three years of ore

production.

Package #3 - Processing Plant Construction and Equipment

The Company has engaged Jinpeng to complete the detailed engineering design of the processing plant

based on the 2021 Feasibility Study. Jinpeng is also finalizing the detailed flowsheet, equipment selection

and cost estimates for the processing plant construction and equipment. The improvements from the

design of the 2021 Feasibility Study are to build a steel- framed building to cover run of ore to avoid

tropical storm leaching, and to cover all equipment and operational facilities with steel-framed building.

The cost estimates are based on the engineering design, initial bidding price for major equipment from

international vendors, market prices for minor equipment in China plus shipping cost, current

construction cost in Ecuador.

The total cost for the processing plant and equipment is estimated at $33.0 million. The major equipment

bid process and ordering are expected to be completed by the end of May 2025. Construction of the main

plant and auxiliary facilities are expected to commence in September 2025, with major equipment

installation expected to commence in May 2026. The Joint Venture expects to complete construction and

equipment installation by November 2026, with commissioning of the process plant occurring in

December 2026.

Power line construction and Stand-by Diesel Power Generators

The Joint Venture is currently updating the engineering work for the power line construction and is in the

process of selecting contractors to construct the power line. The construction of the power line is expected

to be initiated in May 2025 and completed in 13 -17 months. The Joint Venture has also sourced diesel

power generators as standby and emergency power to satisfy Ecuador market conditions . The standby

diesel generators are expected to be in operation before completion of the process plant.

Cost estimates comparison

Compared to the cost estimate of $247.6 million in the 2021 Feasibility Study, differences are:

• Direct costs reduced by $32.6 million to $159.4 million from $192 million, due to savings by

employing a Unit Cost contract and detailed engineering

• VAT reduced by $5.9 million to $19.1 million from $25 million due to reduction of direct costs;

offset by

• Contingency increased by $9.9 million to $31.9 million from $22.0 million; and,

• Owner's costs and burn rates increased by $20.0 million to $30.0 million from $10 million.
