Technical Report on the 阿维诺 Property

阿维诺 Silver and Gold Mines Ltd.(ASM:TSX.V,ASM:NYSE-MKT;“Avino” or “the Company”) 很高兴宣布Tetra Tech(“Tetra Tech”),由Avino委托的独立工程顾问。该技术报告于2012年7月25日在SEDAR上提交,属于公司’s SEDAR profile.

阿维诺财产的技术报告是根据《 NI 43-101矿产项目披露标准》,《伴侣政策》 43-101CP和表格43-101F1编写的,其中包括以下内容:

  • A mineral 资源 estimate and preliminary economics assessment (PEA) on the oxide tailings; and
  • 确定和讨论以硫化物尾矿为开发目标,以圣贡萨洛和阿维诺静脉为目标进行进一步调查。

物业位置

The 阿维诺 Property is located 82 墨西哥杜兰戈东北方公里。

矿产资源讨论

  • 氧化尾矿 - A mineral 资源 was estimated for the oxide tailings generated from prior historical mining operations, using ordinary kriging (OK) interpolation and uncapped grades. The assay values for this estimate are based on 28 drill holes, which were completed on the tailings by CMMA in 1990, and include 407.75 米的钻探和383种金和银测定法。氧化物尾矿估计包含2.34 Mt inferred mineral 资源 at a grade of 91.3 g/t silver and 0.54 g/t gold, with a 50 g/t silver cut-off. The entire 资源 is classified as an inferred mineral 资源, based on the historical nature of the drilling (prior to the institution of NI 43-101 and associated quality assurance/quality control (QA/QC) requirements). Verification samples collected by 利乐科技 confirmed the presence of gold and silver mineralization at grades similar to those obtained in the original tailings drilling campaign and confirmed that the Mine’实验室的检测方法与外部实验室没有实质性区别。是利乐科技’s opinion that the oxide tailings sampling data are considered sufficient to support the purpose of the Technical Report and a current inferred mineral 资源.
  • 硫化尾矿 -硫化物尾矿覆盖了一部分氧化物尾矿,并且主要来源于深部地下作业的材料。目前尚不清楚两者之间化学差异的真正本质是什么,但是它们的颜色明显不同。在没有任何确定的采样数据可以穿透桩的深度的情况下,硫化物尾矿充其量只是一个勘探目标。
  • 圣贡萨洛静脉 -San Gonzalo静脉系统位于2 阿维诺主矿东北方公里。它构成了超过25个强烈发育的静脉系统 跨度m,趋向300至325度,倾斜80 NE to 70 SW。历史上曾开采过该矿脉,地下工程遍及约150个区域 m沿罢工和136 m in depth. An historical mineral 资源 was estimated on the San Gonzalo vein and disclosed in 2009 by Dave Gunning of Orequest Consultants. As there have been the subsequent development of a ramp, bulk sampling, production, channel sampling and additional delineation drilling along the vein, these developments have effected a material change in the 2009 资源 estimate. 利乐科技 is therefore of the opinion that the 2009 资源 calculation can no longer be considered current, and thus there is no current mineral 资源 estimate for the San Gonzalo vein portion of the Property.
  • 阿维诺 Main Vein (ET Zone) –Avino静脉开采是在2001年之前的27年露天开采和地下开采过程中进行的。该开采率为1.6 km long and 60 米宽的表面。开采的最深层是2,070级(330 m below the surface). There is no current mineral 资源 estimate for the 阿维诺 Vein. This vein is a target for future study.

氧化尾矿

选矿,冶金测试和回收方法

利乐科技研究了重力分离,浮选,氰化物浸出,纸浆碳和堆浸处理方法。利用这些测试产生的回收率和工艺条件,确定了使用所选工艺选项建设加工厂的资本成本,同时确定了与每个选项相关的运营成本并编制了财务模型。堆浸操作表明最好的财务选择。

开采方法

The oxide tailings mineral 资源 will be mined through surface methods and without blasting. Initially, the oxide tailings will be processed without having to move the sulphide tailings which cover a portion of the oxide tailings. Approximately 0.5 氧化尾矿将每年发送至堆浸垫。

经济分析

A preliminary economic assessment should not be considered to be a prefeasibility or feasibility study, as the economics and technical viability of the Project have not been demonstrated at this time. The preliminary economic assessment is preliminary in nature and includes inferred mineral 资源s that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral 保留s. Furthermore, there is no certainty that the preliminary economic assessment will be realized. Mineral 资源s that are not mineral 保留s do not have demonstrated economic viability.

利乐科技 prepared an economic evaluation of the Project, based on a pre-tax financial model.

推荐建议

技术报告包含以下建议,以进一步开展工作:

资源估算

  • In order to improve confidence in the inferred mineral 资源 of the oxide tailings and evaluate the overlying sulphide tailings, a sonic drill program of 90 holes with 50 m x 50 m钻collar间距总计1,800 m is recommended.
  • 为了矿山规划的目的,应该完成阿维诺矿脉,圣贡萨洛矿脉和尾矿的ET区的资源估算。
  • 在进行估算之前,应合并钻孔数据库并更新开采消耗。

处理

  • 从氧化物尾矿和硫化物尾矿中获取足够量的样品,以获得具有代表性的样品,用于化验和冶金测试工作,以确定矿床的品位以及从堆浸过程中回收银和金。
  • 使用来自冶金测试工作程序的冶金结果来确认/定义在垫板上的浸出时间,试剂消耗量以及银和金的沉淀效率。
  • 使用来自冶金测试工作程序的冶金结果来准备经济分析,以处理氧化尾矿坝材料,硫化物尾矿坝材料以及处理氧化物尾矿坝材料和硫化物尾矿材料。

环境因素

  • 应该进行详细的权衡研究,以表征硫化物尾矿的当前状况,并确定对该材料的再处理是否将有助于该项目的盈利。

矿产资源说明

Mineral 资源s that are not mineral 保留s do not have demonstrated economic viability. The PEA is preliminary in nature as it includes inferred mineral 资源s that are considered too speculative geologically to have the economic considerations applied to them that would enable to them to be categorized as mineral 保留s. At this time there is no certainty that the results of the PEA will be realized.
