CGG:CC - China Gold International Resources Corp. Ltd. Announces Updated Mineral Resource for CSH Gold Property -- M&I Estimates Increased 151%
(TheNewswire)
VANCOUVER – TheNewswire- August 19 , 2022 — ChinaGold International Resources Corp. Ltd. (TSX:CGG ) and ( HKEx:2099) (“ China Gold International Resources ”,“ CGG ”, or the“ Company ”) todayannounced that it has filed on SEDAR a National Instrument 43-101 — Standards ofDisclosure for Mineral Projects (“ NI43-101 ”) Technical Report with respect to thenew Mineral Resource estimates for the Chang Shan Hao ( “ CSH ”) GoldProject (the “ Project ”) in Inner Mongolia Autonomous Region, the People’sRepublic of China.
The current life of mine for the Project runs untilOctober 2025 at a production rate of 40,000 tonnes per day(“ tpd” ). The Companyhas been carrying out exploration programs aimed at extending the areaof known mineralization and determining mineral resources at depththat could be mined as an underground operation following thedepletion of the mineral reserves at the open pit operations.
Highlights
-
Measured and Indicated Mineral Resources mainly outsideand below the ultimate shell of the existing open pit mine increasedby 151% from 56.6 tonnes ( ”) (1.82 million ounces “Moz”) to142 t 4.57 Moz ) of gold at an average grade of 0.63 g/t Au, providing basisfor further studies on development of the mineral resources atdepth;
-
For the existing open pit, Proven and Probable MineralReserves increased by 18% from 26.3 t (0.85 Moz) to 31 t 1 Moz) of gold atan average grade of 0.65 g/t Au;
-
Mining production rate at northeast open-pit operationis planned at 40,000 tpd or 13.2 million tonnes per annum( Mtpa ”) of run-of-mine(“ ROM ”) ore from 2022to 2025; and
-
Annual gold production is estimated at 4.6 t or 147,893oz from current open-pit operation between April 2022 and October2025
Overview
The CSH Gold Project is a brown-field explorationproject . The target zonesare located outside and below the ultimate shell of the existing openpit mining operation. The Project is located in Wulate Middle Banner,Bayannao’er City, Inner Mongolia Autonomous Region, the People’sRepublic of China, about 630 kilometresnorthwest 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, andmining operation reported in the technical report.
Geology
Tectonically, the CSH gold deposit is located in theNorth China platform, proximal to the edge of North China platformwith contact to the Junggar ? InnerMongolia ? Hinggan fold belt, and hosted in the Bilute Formation of Mesoproterozoic Bayan OboGroup. T he gold mineralization is controlled bya brittle-ductile shear structure, which is likely developed along thecontact between physical hard rocks and soft rocks, but preferentiallywithin the soft horizon.
Mineral Resource Estimate
A Mineral Resource estimate, with an effective date ofApril 1, 2022, has been completed by CGME Consulting Ltd.(“ CGME ”) in accordancewith the CIM Definition Standards and Best Practice Guidelines underNI 43-101, based on a Reasonable Prospect for Eventual EconomicExtraction. The updated Mineral Resource isdelineated based on 368 drill holes totaling 158,092 m completed as ofMarch 2022, of which 65 drill holes totaling 51,986 m were newlycompleted prior to this resource estimate.
The Mineral Resources are summarized in Tablebelow.
