GEOLOGICAL PERSPECTIVE地质远景

  • Uranium Resource – 11.6Mt @ 425ppmU3O8@425ppmU3O8>for contained inferred resource of 10.8Mlbs cut off used was 150ppmU3O8.

  铀矿资源–1160万吨,品位425 ppm u3o8至425 ppm u3o8,其中推断矿产资源量1080万磅,采用的边界品位为150 ppm u3o8。

  • A mining lease (M38/1253) has been applied for over the area of mineralisation;

  • 已经在矿化区域,申请一个采矿租约区(M38/1253);

  • Secondary Uranium mineralisation.

  • 属于次生铀矿化矿床

  The Thatcher Soak Uranium Project is 100% owned by Magnis Resources and located approximately 160km Northeast of Laverton in the Yilgarn Province of Western Australia and covers an area of approximately 150 hectares. The principal exploration target for the area is the drainage system that contains the calcrete and silcrete units that host the carnotite-bearing secondary uranium mineralisation. Mineralisation is tabular and lies at a shallow depth between 0-17m. Magnis Resources has drilled 826 Aircore holes, 40 RAB holes and 12 Sonic Core holes defining a mineralised area with an Inferred Mineral Resource of >11.6Mt @ 425ppmU3O8; for contained inferred resource of 10.8Mlbs  Cut off used was 150ppmU3O8.

  Thatcher Soak铀矿项目的100%股份由马格尼斯资源公司持有,该项目位于西澳大利亚州伊尔冈砷拉弗顿东北大约160公里处,占地面积约150公顷。该区域的主要勘探目标是,含有钙质结砾岩和钒钾铀矿砾岩石单元的水系,这些岩石赋存着含有钒钾铀矿的次生矿化带。这种矿化带属于板状,其埋藏深度浅,介于0-17米之间。马格尼斯资源公司已经钻探826个Aircore孔,40个旋转空气冲击钻孔以及12个Sonic Core孔,在圈定的矿化区域内,推断矿产资源为1160万吨,品位425ppm u3o8,其中推断资源含量为1080万磅,所采用的边界品位为150 ppm u3o8。

   The Uranium mineralisation has similarities to other calcrete channel hosted Uranium deposits in the region including Yeelirrie, Lake Way and Centipede.

  铀矿化区域类似于该地区其他钙质结砾岩通道型铀矿床,包括伊利里、湖路和蜈蚣矿床。

  The Thatcher Soak exploration has defined mineralisation within most of the identified channel and although further adjacent exploration into the ‘dog-leg’ area in the central eastern part of the resource is likely to extend the known mineralisation there are other aspects for an upside in the Thatcher Soak Deposit. Although it is known that the channel sediment unconformably overlies the crystalline basement rocks the gap between basement and the base of known resources is relatively unknown for thickness and potential mineralisation, future investigations could target this zone for potential mineralisation associated with the sands and silts within the lower channel zone. Project upside includes potential increase in head grade as there are now clear indications that a discounted factor for disequilibrium of 0.9 relied heavily upon in the resource estimate was under stating grade and this could be increased to a factor of 1.0 or more if ambiguous regression interpretations can be clarified by additional data. This could increase the grade by 10% or more and subsequently increase the available Uranium. Given the nature of uranium mineralisation within calcrete deposits the higher grades can be hidden within downhole gamma results and programs that include bulk sampling or other methods of acquiring larger representative samples for XRF analysis can prove realistic grade relationships.

  Thatcher Soak项目的勘探工作已在大部分通道内,确定出了矿化区域,虽然在该资源区域中东部的“狗腿型”区域,开展进一步相邻勘探作业,有可能是对已知矿化区域进行延伸,但是对于撒切尔浸泡的矿床资源来说,还有其他因素证明其扩大的潜力。虽然已知任命,通道型沉积呈非整合型,覆盖于结晶基底岩石上,但是该基底和已知资源基础之间的差距相对未知,包括厚度和潜在的矿化情况,因此未来的研究可以将这一区域作为目标,研究下方通道区域内砂砾及淤泥相关的潜在矿化情况。项目资源扩大的潜力包括,原矿品位可能出现增加,因为现在有明确的迹象表明,在资源估算中,0.9的失衡折让因子均将位于开始品位之下,这一因子可以增加到1.0或更大,只要有额外的数据可以对模糊回归的解释明确化。这可能会使品位增加10%或更多,从而增加可利用铀的资源量。由于钙质矿床内的铀矿的矿化性质,下向钻孔的伽马结果可能掩盖较高品位,有关作业程序,包括在进行XRF分析时,采用的批量取样或其他获取具有更大代表性样品的方法,可以证明存在这种现实品位的关系。
