Volume 14 • Issue 4 | 2017 | ASIA Miner | 41 China 希尔威矿业探明更多矿化区域 希尔威金属矿业公司在Ying矿区通过坑内钻探和掘 域。该钻探是HZG, HPG, LMW, TLP和 LME 的一部分。 2017年上半年,在HZG, HPG和LMW矿区,该公司完成 了21,675米的坑内钻探和7,989 围内现有作业面以下探明了显著的高品位矿化区, 特别是在HZG 的HZ20和 HPG 额的H17。 坑内钻探持续在3座矿山的矿脉走向和下倾方向上扩 域对已知矿脉结构的走向和下倾方向的延伸进行圈 在6个月内,希尔威在TLP和LME完成了17,230米的坑 内钻探和6,196 探明了高品位的成矿区域。 2季度,Ying矿区矿石开采量为160,408吨,较2016 年同期的173,508吨下降了8%,主要原因是中国国家 电网对电网升级改造导致的数日电力供应中断。这 影响了TLP, LMW 和 LME矿区,同时提升机维护和电 缆铁芯更换影响了SGX 和HZG矿区。 2季度,矿产品销售量为银130万盎司,铅1380万 磅,锌70万磅,2016年同期数据为银150万盎司,铅 1490万磅,锌180万磅。 2季度,希尔威位于广东的GC矿的开采量为64,865 吨,较2016年同期的64,349略微提高。GC矿销售银 189,000盎司,铅210万磅,锌420万磅,2016年同期 数据分别为银149,000盎司,铅190万磅,锌340万 磅. 该季度,GC矿完成了4,972米的坑内钻探和5,292i的 UNDERGROUND drilling and exploration tunnelling by Silvercorp Metals at Ying Mining District continue to identify high-grade min- eralisation beneath current production levels. The drilling is part of 2017 exploration at the HZG, HPG, LMW, TLP and LME mines. At HZG, HPG and LMW the company completed 21,675 metres of underground diamond drilling and 7989 metres of exploration tunnelling in the first half of 2017. The tunnelling, which comprised comprising drifting, crosscutting and raising, exposed significant high-grade mineralised zones be- neath current production levels within major production veins, espe- cially HZ20 at HZG and H17 at HPG. Underground drilling continuously extended major mineralised vein structures along strike and down dip at the three mines. The drilling is mainly conducted from current production levels to de- lineate the down dip and along-strike extensions of known miner- alised vein structures in the production area and test for new veins in the less-explored areas. During the six months, Silvercorp completed 17,230 metres of underground diamond drilling and 6196m of exploration tunnelling at TLP and LME. This extended major mineralised vein structures along strike and down dip while tunnelling exposed high-grade min- eralised zones. During the June quarter at Ying Mining District 160,408 tonnes of ore was mined, down 8% on the 173,508 tonnes in the same period of 2016 mainly due to downtime arising from several power down days caused by power grid upgrades by State Grid Corpora- tion of China. These impacted the TLP, LMW and LME mines while hoist maintenance and cable steel replacement impacted SGX and HZG. There were approximately 1.3 million ounces of silver, 13.8 million pounds of lead and 700,000 pounds of zinc sold, compared to 1.5 million ounces silver, 14.9 million pounds lead, and 1.8 million pounds of zinc in the June quarter of 2016. At GC mine in Guangdong province Silvercorp mined 64,865 tonnes, up slightly from 64,349 tonnes in the corresponding 2016 quarter. GC sold 189,000 ounces of silver, 2.1 million pounds of lead and 4.2 million pounds of zinc compared to 149,000 silver ounces, 1.9 million pounds of lead and 3.4 million pounds of zinc in the 2016 quarter. During the quarter 4972 metres of underground drilling and 5292 metres of tunnelling were carried out at GC. Silvercorp identifies more mineralisation Silvercorp Metals' SGX mine in the Ying Mining District in Henan province.
