VANCOUVER – TheNewswire - June 30 , 202 6 — China Gold International Resources Corp. Ltd. (TSX:CGG and HKEx: 2099) (“ China Gold International Resources ”, “ CGG ”, or the “ Company ”) today announced that it has completed mineral resource and reserve estimate update and the NI 43-101 Technical Report with respect to the Mineral Resource and Reserve E stimates Update for the Jiama (“ JIAMA ”) Copper Polymetallic Project (the “ Project ”) in Tibet Autonomous Region , the People’s Republic of China.

Following an extensive exploration campaign, the Company has completed a major update to the Mineral Resource and Mineral Reserve estimates for the Jiama Copper Polymetallic Project. The updated Mineral Resource significantly expands the Project's scale and development potential, providing a robust foundation for future production expansion, mine life extension and further technical studies on larger-scale mining scenarios.

The updated Mineral Resource and Mineral Reserve estimates have been depleted to account for production up to December 31, 2025. The significant increase in the updated estimates reflects the success of the Company's multi-year exploration programs, which have substantially expanded the known mineralized system and delineated additional mineral resources and reserves at depth and in surrounding areas of the Jiama Project.

Highlights

• Measured mineral resource increased 523% from 100 Mt to 623 Mt.  

• Total mineral resource of metal amounts has increased significantly. Compared with resource estimate in 2012 by Mining One, The Measured and Indicated r esources are 1335 Mt with copper metal increasing by 3 million tonnes, gold by 7.12 million ounces, silver by 247.23 million ounces. The inferred resources are 454.7 Mt with copper metal increased by 1.74 million tons, gold by 2.72 million ounces, silver by 116.3 million ounces.  

• The average grade of the updated Measured Mineral Resources is 0.6 % Cu or 1.12% CuEq, while the average grade of the updated Inferred Mineral Resources is 0.6 % Cu or 1.0 % CuEq, reflecting the high quality of the significantly expanded Mineral Resource.  

• Total reserve increased 51% from 440 Mt to 665 Mt.  

• Compared to the 2013 Reserve Estimates by Mining One, the current open-pit ore reserves have dropped from 240 million tons to 110 million tons although it still can support more than 20 year mine life for two current open pit operation at the current mining capacities.  

• Underground ore reserves have increased from 200 million tons in 2013 to 550 million tons, copper metal from 1.47 million tons to 5.2 million tons, molybdenum from 100,000 tons to 220,000 tons, gold from 2 million ounces to 8 million ounces, and silver from 88 million ounces to 354 million ounces  

• The average grade of the updated Mineral Reserves is 0.86% Cu or 1.40% CuEq, providing a strong foundation for future production expansion and mine life extension.  

• The new mineral resource providing basis for further studies on the proposed large open pit studies on the Jiama project  

Overview

Jiama Copper polymetallic Project is a large metallic deposit of copper, molybdenum, gold, silver, lead, and zinc. Tibet Huatailong Mining Development Company (“ Huatailong ” or “ Huatailong Company ”), a subsidiary of China Gold International Resources Corporation ("CGG"), listed on the Toronto Stock Exchange in Canada and the Hong Kong Stock Exchange in China, owns 100% of the Jiama project. Development of the Jiama copper polymetallic mine began at the beginning of this century.

The first phase of the Jiama project's Tongqianshan and Niumatang open pit mine began commercial operation in 2010. The Phase II development and expansion was completed in 2018. Currently, the Jiama project is operating at a production rate of 34,000 tons per day and is expected to return to its designed capacity of 50,000 tons per day in 2028.

Currently, Huatailong runs two open-pit mines and two underground mining district s in one underground mine at Jiama.

Geology

The Jiama mining area is in the Gangdise Cu, Mo, Pb, Zn, Au and Ag metallogenic belt of the Tethys-Himalayan orogenic region, one of the world's major porphyry copper ore-forming regions. The geo-tectonics lie in the northern middle segment of the Late Yanshanian Gangdise – Early Himalayan epicontinental magmatic arc in the Gangdise-Nyenqing Tangura secondary structural unit with multi-stage and multi-type magmatic activities and structural-processes, providing favorable geological conditions for mineralization. The rock types within the Jiama mining area are usually passive epicontinental clastic rocks and carbonate rocks. The strata consist of the Upper Jurassic Duodigou Formation dominated by marble and limestone, and the Lower Cretaceous Linbuzong Formation dominated by sandstone, slate and hornfels. The mining area is located at the front section of the regional thrust system. The structure plays a role in allocating and storing magma and ore-bearing fluids, mainly through the south-to-north slip-over and the north-to-south thrust-over in the area, specifically through interlayer slip structures and the resulting secondary fold controls the mineralization bodies.

Within the Jiama mining area, there are three types of copper polymetallic mineralization: skarn, hornfels, and porphyry mineralization. These three types of mineralization form a complete porphyry mineralization system.

Mineral Resource Estimate

A Mineral Resource estimate, with an effective date of June 30, 2026, has been completed by Changchun Gold Design Institute (“CGDI”) in accordance with the CIM Definition Standards and Best Practice Guidelines under NI 43-101, based on a Reasonable Prospect for Eventual Economic Extraction. The updated Mineral Resource is delineated based on 582 surface drilling holes totaling 289342.79 m and 150 underground drilling holes totaling 20958.46m completed as of December 31 of 2025.

The Mineral Resources are summarized in Table below.
