VANCOUVER – TheNewswire - August 19, 2022 — China Gold International Resources Corp. Ltd. (TSX:CGG) and (HKEx:2099) (“China Gold International Resources”, “CGG”, or the “Company”) today announced that it has filed on SEDAR a National Instrument 43-101 — Standards of Disclosure for Mineral Projects (“NI 43-101”) Technical Report with respect to the new Mineral Resource estimates for the Chang Shan Hao (“CSH”) Gold Project (the “Project”) in Inner Mongolia Autonomous Region, the People’s Republic of China.

The current life of mine for the Project runs until October 2025 at a production rate of 40,000 tonnes per day (“tpd”). The Company has been carrying out exploration programs aimed at extending the area of known mineralization and determining mineral resources at depth that could be mined as an underground operation following the depletion of the mineral reserves at the open pit operations.  

Highlights

• Measured and Indicated Mineral Resources mainly outside and below the ultimate shell of the existing open pit mine increased by 151% from 56.6 tonnes (”) (1.82 million ounces “Moz”) to 142 t 4.57 Moz) of gold at an average grade of 0.63 g/t Au, providing basis for further studies on development of the mineral resources at depth; 

• For the existing open pit, Proven and Probable Mineral Reserves increased by 18% from 26.3 t (0.85 Moz) to 31 t 1 Moz) of gold at an average grade of 0.65 g/t Au; 

• Mining production rate at northeast open-pit operation is planned at 40,000 tpd or 13.2 million tonnes per annum (Mtpa”) of run-of-mine (“ROM”) ore from 2022 to 2025; and 

• Annual gold production is estimated at 4.6 t or 147,893 oz from current open-pit operation between April 2022 and October 2025 

Overview

The CSH Gold Project is a brown-field exploration project. The target zones are located outside and below the ultimate shell of the existing open pit mining operation. The Project is located in Wulate Middle Banner, Bayannao’er City, Inner Mongolia Autonomous Region, the People’s Republic of China, about 630 kilometres northwest of Beijing. Inner Mongolia Pacific Mining Co., Ltd., a 96.5% subsidiary of the Company, owns a 100% interest in the Project area, including all mineral resource and mineral reserve estimates, and mining operation reported in the technical report.

Geology

Tectonically, the CSH gold deposit is located in the North China platform, proximal to the edge of North China platform with contact to the JunggarInner MongoliaHinggan fold belt, and hosted in the Bilute Formation of Mesoproterozoic Bayan Obo Group. The gold mineralization is controlled by a brittle-ductile shear structure, which is likely developed along the contact between physical hard rocks and soft rocks, but preferentially within the soft horizon.

 

Mineral Resource Estimate

A Mineral Resource estimate, with an effective date of April 1, 2022, has been completed by CGME Consulting Ltd. (“CGME”) 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 368 drill holes totaling 158,092 m completed as of March 2022, of which 65 drill holes totaling 51,986 m were newly completed prior to this resource estimate.

 

The Mineral Resources are summarized in Table below.

Notes: Mineral Resources are reported in relation to a conceptual open-pit mining and underground block caving mining. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. All figures are rounded to reflect the relative accuracy of the estimate. Raw assays have been capped. Mineral Resources include Mineral Reserves.

Mineral Resources are reported at a cut-off grade of 0.28 g/t Au for open-pit mining, based on the following parameters: the heap leaching & metallurgical recovery of 60% and gold bullion market price of USD 1,980 per ounce. Additional Mineral Resources are reported at a cut-off grade of 0.30 g/t Au for underground block caving mining, based on the following parameters: the heap leaching & metallurgical recovery of 60% and gold bullion market price of USD 1,980 per ounce. USD 1.0000=RMB 6.3457 dated in April 2022, and one troy ounce is equal to 31.1035 grams.

Mineral Reserve Estimate

For the existing open pit mining operation, a Mineral Reserve estimate, dated effective April 1, 2022, has been completed by CGME in accordance with the CIM Definition Standards and Best Practice Guidelines under NI 43-101.
