From October 1, 2019 to June 30, 2021 , 72,878 metres ("m") from a total of 704 underground diamond drill holes were completed at the GC mine, including 27,527 m from 268 holes completed in the first six months of 2021.  Assay results for all the holes have been received, with 577 holes intercepting mineralization.

 

The diamond drilling program at the GC mine targeted: (1) blocks of known silver-lead-zinc veins in and above the production area; and (2) exploration drilling at higher elevations in the north and south sides of the resource areas.

 

  Drilling Intersected Thick and High-Grade Veins In and Above the Production Areas  

 

Detailed drilling of blocks of known silver-lead-zinc veins in and above the GC mine production areas intersected high-grade veins. These mineralized occurrences were previously missed due to limited drilling and tunneling, changes in the strikes and dips, and/or pinch-swelling of the pay-zones in the veins.

 

The high-grade intercepts from this period are associated with parallel silver-lead-zinc veins V2-2, V2-3, V2-4, V2-4E, V2-7, V2E, V2E1, V2E6, V2W, V2W-4, V2W-9, V5-7, V5-9, V7, V7-1, V7-1E, V7-3, V9-4, V9-5, V9W-2N, V9W-5, V10, V10-1, V10-20, NV10, V19, V19-8, V25, V25-1, and V25-4. Other veins include V11, V16, and NV28.  There are 24 new vein structures discovered in and above the production areas, including V2E4, V2E-4E, V2E-8, V7-2, V7-5, V7S, V8-2, V8-5, V10-10, V10-11, C10-17, V10-1S, V10W, V18-2, V18-3, V18-4, V19-2, V19-7, and V19-8. The Company is currently working on a technical report on the GC mine to update the resources and reserves as of December 31, 2020 . It is expected that mineralization in these structures can be converted quickly into reserves and mined with existing underground workings.

  Tunneling Programs at the GC Mine  

 

In addition to the drilling program, 16,070 m of exploration drift tunneling were developed at the GC mine during this period. The exploration tunneling, comprised of drifting, cross-cutting and raising, was driven along and across major mineralized vein structures to upgrade the drill-defined mineral resources and test for new parallel and splay structures. The results of the exploration tunneling are summarized in the following table.

  Quality Control  

 

Drill cores are NQ size. Drill core samples, limited by apparent mineralization contacts or shear/alteration contacts, were split into halves by saw cutting. The half cores are stored in the Company's core shacks for future reference and checks, and the other half core samples are shipped in securely sealed bags to the on-site laboratory (Laboratory of Guangdong Found).

 

Channel samples are collected along sample lines perpendicular to the mineralized vein structure in exploration tunnels. Spacing between sampling lines is typically 5 m along strike. Both the mineralized vein and the altered wall rocks are cut by continuous chisel chipping. Sample length ranges from 0.2 m to more than 1 m , depending on the width of the mineralized vein and the mineralization type. Channel samples are shipped in securely sealed bags to the on-site laboratory.

 

For analysis, the   sample is dried and crushed to minus 1 mm and then split to a 200-300 g subsample which is further pulverized to minus 200 mesh. Two subsamples are prepared from the pulverized sample. One is digested with two-acids for analysis of silver, lead, zinc and copper with atomic absorption spectroscopy (AAS), and the other is retained as pulp reject at the lab for future reference.

 

A routine quality assurance/quality control (QA/QC) procedure is adopted to monitor the analytical quality at each lab. Certified reference materials (CRMs), pulp duplicates and blanks are inserted into each batch of lab samples. QA/QC data at the lab are attached to the assay certificates for each batch of samples.

 

The Company maintains its own comprehensive QA/QC program to ensure best practices in sample preparation and analysis of the exploration samples. Project geologists regularly insert CRMs, field duplicates and blanks to each batch of 30 core samples to monitor the sample preparation and analysis procedures at the labs. The analytical quality of the labs is further evaluated with external checks by sending approximately 3-5% of the pulp samples to higher level labs to check for lab bias.  Data from both the Company's and the labs' QA/QC programs are reviewed on a timely basis by project geologists.

Any statements or information that express or involve discussions with respect to predictions, expectations, beliefs, plans, projections, objectives, assumptions or future events or performance (often, but not always, using words or phrases such as "expects", "is expected", "anticipates", "believes", "plans", "projects", "estimates", "assumes", "intends", "strategies", "targets", "goals", "forecasts", "objectives", "budgets", "schedules", "potential" or variations thereof or stating that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved, or the negative of any of these terms and similar expressions) are not statements of historical fact and may be forward-looking statements or information.  Forward-looking statements or information relate to, among other things: the price of silver and other metals; the accuracy of mineral resource and mineral reserve estimates at the Company's material properties; the sufficiency of the Company's capital to finance the Company's operations; estimates of the Company's revenues and capital expenditures; estimated production from the Company's mines in the Ying Mining District; timing of receipt of permits and regulatory approvals; availability of funds from production to finance the Company's operations; and access to and availability of funding for future construction, use of proceeds from any financing and development of the Company's properties.  

 

  Forward-looking statements or information are subject to a variety of known and unknown risks, uncertainties and other factors that could cause actual events or results to differ from those reflected in the forward-looking statements or information, including, without limitation, risks relating to: social and economic impacts of COVID-19; fluctuating commodity prices; calculation of resources, reserves and mineralization and precious and base metal recovery; interpretations and assumptions of mineral resource and mineral reserve estimates; exploration and development programs; feasibility and engineering reports; permits and licenses; title to properties; property interests;  joint venture partners; acquisition of commercially mineable mineral rights; financing; recent market events and conditions; economic factors affecting the Company; timing, estimated amount, capital and operating expenditures and economic returns of future production; integration of future acquisitions into the Company's existing operations;  competition;  operations and political conditions; regulatory environment in China and Canada;  environmental risks; foreign exchange rate fluctuations; insurance; risks and hazards of mining operations; key personnel; conflicts of interest; dependence on management; internal control over financial reporting as per the requirements of the Sarbanes-Oxley Act; and bringing actions and enforcing judgments under U.S. securities laws.  

 

  This list is not exhaustive of the factors that may affect any of the Company's forward-looking statements or information. Forward-looking statements or information are statements about the future and are inherently uncertain, and actual achievements of the Company or other future events or conditions may differ materially from those reflected in the forward-looking statements or information due to a variety of risks, uncertainties and other factors, including, without limitation, those referred to in the Company's Annual Information Form for the year ended March 31, 2021 under the heading "Risk Factors".  Although the Company has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated, described or intended.  Accordingly, readers should not place undue reliance on forward-looking statements or information.  

 

  The Company's forward-looking statements and information are based on the assumptions, beliefs, expectations and opinions of management as of the date of this press release, and other than as required by applicable securities laws, the Company does not assume any obligation to update forward-looking statements and information if circumstances or management's assumptions, beliefs, expectations or opinions should change, or changes in any other events affecting such statements or information. For the reasons set forth above, investors should not place undue reliance on forward-looking statements and information.  

 

   CAUTIONARY NOTE TO US INVESTORS   

 

  The disclosure in this news release and referred to herein was prepared in accordance with NI 43-101 which differs significantly from the requirements of the U.S. Securities and Exchange Commission (the "SEC").  The terms "proven mineral reserve", "probable mineral reserve" and "mineral reserves" used in this news release are in reference to the mining terms defined in the Canadian Institute of Mining, Metallurgy and Petroleum Standards (the "CIM Definition Standards"), which definitions have been adopted by NI 43-101.  Accordingly, information contained in this news release providing descriptions of our mineral deposits in accordance with NI 43-101 may not be comparable to similar information made public by other U.S. companies subject to the United States federal securities laws and the rules and regulations thereunder.  

 

  Investors are cautioned not to assume that any part or all of mineral resources will ever be converted into reserves. Pursuant to CIM Definition Standards, "Inferred mineral resources" are that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling.  Such geological evidence is sufficient to imply but not verify geological and grade or quality continuity.  An inferred mineral resource has a lower level of confidence than that applying to an indicated mineral resource and must not be converted to a mineral reserve. However, it is reasonably expected that the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration.  Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases.  Investors are cautioned not to assume that all or any part of an inferred mineral resource is economically or legally mineable.  Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures.  

 

  Canadian standards, including the CIM Definition Standards and NI 43-101, differ significantly from standards in the SEC Industry Guide 7.  Effective February 25, 2019 , the SEC adopted new mining disclosure rules under subpart 1300 of Regulation S-K of the United States Securities Act of 1933, as amended (the "SEC Modernization Rules"), with compliance required for the first fiscal year beginning on or after January 1, 2021.  The SEC Modernization Rules replace the historical property disclosure requirements included in SEC Industry Guide 7.  As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of "Measured Mineral Resources", "Indicated Mineral Resources" and "Inferred Mineral Resources".  In addition, the SEC has amended its definitions of "Proven Mineral Reserves" and "Probable Mineral Reserves" to be substantially similar to corresponding definitions under the CIM Definition Standards.  During the period leading up to the compliance date of the SEC Modernization Rules, information regarding mineral resources or reserves contained or referenced in this news release may not be comparable to similar information made public by companies that report according to U.S. standards.  While the SEC Modernization Rules are purported to be "substantially similar" to the CIM Definition Standards, readers are cautioned that there are differences between the SEC Modernization Rules and the CIM Definitions Standards.  Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules.

Editor's Picks: Silver Price Hits 13 Year High, Gold Takes a Breather

Gold was on the decline this week, closing just below US$3,370 per ounce, after tensions in the Middle East pushed it past the US$3,430 level toward the end of last week.

All eyes were on the US Federal Reserve, which in a widely expected move left interest rates unchanged on Wednesday (June 18) following its two day meeting. The central bank cut rates in December 2024, but has kept them steady for its last four gatherings.

US President Donald Trump wasn't pleased, calling Powell "too late" in a Thursday (June 19) post on Truth Social. While speculation that Trump will fire Powell has died down, the president did recently say he intends to announce his next pick for the Fed leader position "very soon."

10 Silver ETFs for Every Investing Style in 2025

Investors looking for exposure to the silver price and silver-mining companies should consider silver exchange-traded funds (ETFs).

Spurred by moves in the gold market, safe-haven buying as well as increasing demand from industrial sectors, silver saw strong price movements in the first half of 2025, breaching US$37 per ounce for the first time since 2011.

While silver has often been seen as a more approachable precious metal owing to its lower per ounce price, its performance has lagged gains seen in the gold price over the past few years. However, silver stole some of the spotlight in the second quarter of 2025 as it saw significant gains on the back of geopolitical tension and economic uncertainty from the US trade and tariff policy.

Silver Price Surges to US$37, Highest Value Since May 2011

After being overshadowed by gold early in the year, silver has been in the spotlight in recent weeks.

The white metal broke through the US$37 per ounce mark on Tuesday (June 17) for the first time since May 2011.

Recent economic and geopolitical events have raised analysts’ expectations of a September rate cut from the US Federal Reserve, helping to fuel safe-haven buying of silver and gold.
