Silvercorp Metals (TSX:SVM) has recently reported the results of its extensive diamond drilling program at the HPG mine, located in China’s Ying Mining District. The company’s operations, conducted from the beginning of 2022 through mid-November 2023, encompassed a comprehensive exploration initiative.
The drilling program extended over a period of almost two years, during which the company drilled a total of 45,046 meters across 297 diamond drill holes. This intensive effort included 215 underground and 82 surface holes. As of now, the assay results for 270 of these holes have been received, with 139 holes encountering mineralized zones. To continue this exploration, eight drilling rigs are currently operational at the HPG mine site.
Silvercorp’s drilling initiative at the HPG mine concentrated on three primary areas. The first area, known as the upper zone (U), involved drilling near the surface for gold, silver, lead, and zinc vein structures within the resource area. This part of the mine had seen limited exploration in the past. The second focus area, termed the production zone (P), comprised infill drilling above or beneath previously mined stopes. The stopes had been abandoned earlier due to unexpected variability in ore grades, vein thicknesses, and orientations. The third area, identified as the breccia zone (B), involved testing the mineralization potential within a rhyolitic breccia dyke located within the existing underground mining infrastructure.
In the upper zone, the drilling targeted the strike and downdip extent of known vein structures, particularly above the 600 meters above mean sea level elevation. The results from this drilling revealed high-grade gold, silver, lead, and zinc vein structures at higher elevations. The significant findings in this zone included intercepts from various series, such as H13, H15, H16, H17, H32, H42, and others.
The production zone drilling focused on areas previously underexplored due to variability in ore shoot grades and vein trends below the 600-meter elevation. This drilling campaign led to the discovery and expansion of high-grade resources in several vein series, enhancing the understanding of the mine’s potential.
The breccia zone drilling aimed to assess the extent of mineralization within a rhyolitic breccia dyke, specifically in the B8 area. This zone, characterized by disseminated gold, silver, lead, zinc, and copper mineralization, measured approximately 50 meters in length, 30 meters in height, and 20 meters in width. The B8 orebody, discovered during this exploration phase, has been mined since October 2023 using long-hole stoping techniques.
Furthermore, additional drilling was conducted to explore the down-dip extension of major vein structures, including the H15, H16, and H17 series, below the 300-meter elevation in the Deep Zone (zone D). This exploration confirmed the continuation of mineralization along these structures, expanding the potential for further resource development.
Silvercorp Metals’ extensive and methodical exploration program at the HPG mine reflects a significant commitment to understanding and developing the mine’s resources. The results from this program are likely to influence the company’s future mining strategies and operational decisions in the Ying Mining District.
Highlights from the results are as follows:
