TORONTO, Dec. 19, 2024 (GLOBE NEWSWIRE) -- Wallbridge Mining Company Limited (TSX:WM, OTCQB:WLBMF) ("Wallbridge" or the "Company") today reports the results of its 2024 metallurgical testing program for its Martiniere Gold Project ("Martiniere"). Test work completed by SGS Lakefield Research Ltd. ("SGS Lakefield") indicates gold recoveries of up to 84.8% can be achieved using conventional and proven technologies.
The 2024 metallurgical testing program was done as an initial test to evaluate potential gold recoveries for various grind sizes and processing technologies applied to a representative sample composite collected from five holes drilled along the Bug Lake zone at Martiniere (see map below). Material collected was tested for its amenability to gravity separation, flotation, and cyanidation under varying grind sizes and conditions. Testing shows gold recoveries up to 84.8% can be achieved using a combination of gravity, flotation, regrind and cyanidation of sulfide concentrate and flotation tailings (see table below).
"These initial metallurgical test results are positive and achieve two important objectives," stated Brian Penny, Wallbridge Chief Executive Officer. "First, they demonstrate that good gold recoveries can be attained from Bug Lake mineralization. Second, they indicate these recoveries can be achieved using well-established time-tested mineral processing technologies. Moreover, the information generated by this year's metallurgical testing program at Martiniere provides a solid foundation for the design of future metallurgical and related technical studies as we continue to explore the deposit and advance the project."
Metallurgical test work results:
The grade of the composite sample averaged 3.21 g/t Au. A gold recovery of 18.5% was achieved by gravity separation for material with a P80 grind size of 150 microns ("μm"). Flotation testing conducted on material with a P80 grind size of 83 μm achieved a gold recovery of 89.5%. Cyanidation ('CN') testing done on flotation tailings material yielded a maximum gold recovery of 68.2%. Cyanidation of sulfide concentrate re-ground to P80 at 29 μm and 16 μm returned gold recoveries of 62.0% and 82.9% respectively.
Overall, an average gold recovery of 84.8% was achieved after a 48 hour processing cycle involving a combination of gravity recovery, sulfide flotation, regrind of sulfide concentrate to P80 at 16 μm, and cyanidation of sulfide concentrate and residual flotation tailings.

Quality Assurance / Quality Control
Wallbridge maintains a Quality Assurance/Quality Control ("QA/QC") program for all its exploration projects using industry best practices. Key elements of the QA/QC program include verifiable chain of custody for samples, regular insertion of blanks and certified reference materials, and completion of secondary check analyses performed at a separate independent accredited laboratory. Drill core is halved and shipped in sealed bags to SGS in Val d'Or, Quebec where they are re-distributed to other SGS laboratory facilities according to the analytical method being requested by Walbridge. Gold analyses are routinely performed via fire assay with ICP-OES finish methods. For greater precision and accuracy, samples assaying 10 g/t Au or greater are re-assayed via metallic screen fire assay method or fire assay/gravimetric finish, depending on the amount of sample material remaining available. Samples containing visible gold are submitted directly for analysis by metallic screen fire assay method.
Material collected for metallurgical testing was selected by Wallbridge geologists from individual drill core samples based on their analyzed gold grades and style of mineralization consistent with the broader Bug Lake zone. A total of 180 kilograms of mineralized drill core was collected and submitted to SGS Lakefield Research facility, a division of SGS Canada. SGS Lakefield is the only commercial laboratory that is accredited to ISO Guide 25, supplemented by CAN-P-1579 for mineral analysis.
SGS Natural Resources analytical laboratories operate under a Quality Management System that conforms to the requirements of ISO/IEC 17025. All of SGS' Canadian analytical sites are accredited by the Standards Council of Canada (SCC) for specific mineral tests listed on the scope of accreditation to the ISO/IEC 17025 standard. ISO/IEC 17025 addresses both the quality management system and the technical aspects of operating a testing laboratory. Physical sample preparation involving accredited test methods as listed on the scope of accreditation may be performed at other sites listed on the SGS Canada Inc – Natural Resources – Minerals group accreditation or at offsite sample preparation laboratories that are monitored regularly for quality control and quality assurance practices, including SGS Canada Inc, Garson, SGS Canada Inc, Val d'Or and SGS Canada Inc, Grand Falls-Windsor.

多伦多,2024年12月19日(环球新闻专线)——沃尔布里奇矿业有限公司(多伦多证券交易所股票代码:WM,OTCQB: WLBMF)(“Wallbridge” 或 “公司”)今天公布了其2024年马蒂内尔黄金项目(“马蒂尼埃尔”)冶金测试计划的结果。SGS 莱克菲尔德研究有限公司(“SGS Lakefield”)完成的测试工作表明,使用传统和成熟的技术可以实现高达84.8%的黄金回收率。
2024年的冶金测试计划是作为初步测试完成的,目的是评估应用于从马蒂尼埃尔Bug Lake地区钻探的五个孔中采集的代表性复合样本中采集的各种研磨尺寸和加工技术的潜在金回收率(见下图)。对收集的材料进行了测试,以确定其在不同的研磨大小和条件下是否适合重力分离、浮选和氰化。测试表明,结合使用硫化物精矿和浮选尾矿的重力、浮选、再研磨和氰化可以实现高达 84.8% 的金回收率(见下表)。
Wallbridge首席执行官布莱恩·彭尼表示:“这些初步的冶金测试结果呈阳性,实现了两个重要目标。”“首先,他们表明,Bug Lake矿化可以获得良好的黄金回收率。其次,他们表明这些回收可以通过久经考验的成熟矿物加工技术来实现。此外,在我们继续勘探矿床和推进项目的过程中,今年的马蒂尼埃尔冶金测试项目生成的信息为未来冶金和相关技术研究的设计提供了坚实的基础。”
冶金测试工作结果:
复合样品的平均品位为3.21克/吨金。通过对P80研磨尺寸为150微米(“μm”)的材料进行重力分离,金回收率为18.5%。对P80研磨尺寸为83微米的材料进行的浮选测试实现了89.5%的金回收率。对浮选尾矿材料进行的氰化(“CN”)测试得出的最大黄金回收率为68.2%。硫化物精矿的氰化反应在29微米和16微米处重新研磨成P80,金回收率分别为62.0%和82.9%。
总体而言,经过48小时的加工周期,包括重力回收、硫化物浮选、将硫化物精矿在16 μm处重磨至P80,以及硫化物精矿和残留浮选尾矿的氰化处理相结合,实现了84.8%的平均黄金回收率。

质量保证/质量控制
Wallbridge使用行业最佳实践为其所有勘探项目维持质量保证/质量控制(“QA/QC”)计划。质量保证/质量控制计划的关键要素包括样品的可核查监管链、定期插入空白和经认证的参考材料,以及完成在单独的独立认证实验室进行的二次检查分析。钻芯被切成两半,装在密封袋中运往位于魁北克瓦尔德奥的SGS,在那里根据沃尔布里奇要求的分析方法将其重新分配到其他SGS实验室设施。黄金分析通常通过 ICP-OES 表面处理方法进行火法分析。为了获得更高的精度和准确性,根据剩余样品材料的数量,通过金属丝网火焰分析方法或火焰分析/重量法进行重新分析,金含量为10 g/t Au或更高的样品。含有可见金的样品直接提交给金属屏幕火灾分析方法进行分析。
为冶金测试收集的材料是由Wallbridge地质学家根据分析的金等级和与更广泛的Bug Lake区域一致的矿化风格从单个钻芯样本中选择的。共收集了 180 千克的矿化钻芯,并将其提交给 SGS 加拿大分公司下属的 SGS 莱克菲尔德研究设施。SGS 莱克菲尔德是唯一一家获得 ISO 25 号指南(由 CAN-P-1579 补充的矿物分析)认证的商业实验室。
SGS 自然资源分析实验室在符合 ISO/IEC 17025 要求的质量管理体系下运行。SGS 的所有加拿大分析场所均获得加拿大标准委员会 (SCC) 的认可,可进行 ISO/IEC 17025 标准认证范围内列出的特定矿物测试。ISO/IEC 17025 既涉及质量管理体系,也涉及运营测试实验室的技术方面。涉及认证范围中列出的经认可的测试方法的物理样本制备可在加拿大通用检验集团——自然资源——矿产集团认证中列出的其他地点进行,也可以在定期进行质量控制和质量保证措施监测的场外样本制备实验室进行,包括加拿大SGS公司、Garson、SGS加拿大公司、Val d'Or和SGS加拿大公司、大瀑布温莎公司。
