Sparton Resources has received very positive results from the initial surface sampling program completed on its Rentian Vanadium Project in Jiangxi Province. The sampling identified base metal and silver values, including up to 2% vanadium oxide.

An 1100 metre drilling program using three drill rigs is under way to test the down dip extension of the surface zones sampled. About 1.2km of the 1.6km strike length is being tested in 10-15 shallow holes to intersect the vanadium and base metal rich unit at depths of 25-75 metres. Holes are about 150 metres apart and fill in drilling is planned once the geometry of the mineralized unit is better understood.

The company’s vanadium projects are held by VanSpar Mining, a new subsidiary company that holds Sparton’s various vanadium rights and assets in China, including Rentian and the nearby Guojiaping project.

As part of its ongoing due diligence of the Rentian Mining Licence and processing plant, the company has completed a comprehensive surface sampling program as well as a review of the Rentian processing plant operating systems and infrastructure.

More than 160 grab and chip samples were taken covering most of the vanadium unit rock exposures in the 1.6sqkm licence. There are no previous records of similar sampling and no previous drilling has been done to evaluate the vanadium rich stratigraphic unit which trends across the licence. The sampling covered most of the 1.6km strike length of the vanadium rich horizon. The vanadium rich unit appears to be about 30 metres thick, strikes northwest and dips gently 10-15 degrees to the northeast.

The best continuous chip sample returned an average of 1.10% vanadium oxide across a 24 metre-wide sampled zone. Within this interval a 12 metre wide zone averaged 1.31%. The highest value in this zone was 2% over a 1 metre interval. Other samples included 0.75% over 12 metres and 0.73% over 7 metres.

The average vanadium oxide content for the entire 162 sample group including mineralized and non mineralized zones was 0.43% and about 20% of samples assayed over 1%.

Of significant interest is that significant amounts of copper, zinc and silver are associated with the vanadium mineralization. These were detected in a number of multi element and individual analyses done for the quality control program. Values of 0.92% copper, 0.53% copper, 0.42% copper and 0.05% copper with 0.53% zinc were reported.

Significant silver values were also associated with the higher grade vanadium results. These include 1 metre chip samples grading 39.9 grams/tonne silver with 1.66% vanadium oxide, 23.1 grams/tonne silver with 1.21% vanadium oxide and 18.2 grams/tonne silver with 1.20% vanadium oxide.

钒矿采样工作取得积极的结果 

斯帕顿资源公司旗下的仁天钒矿项目的首次地表采样工作取得了积极的结果,该项目位于中国江西省。采样工作确定了贱金属和银的价值,包括高达2%的钒氧化物。

使用了3个钻机、共计1100米的钻探作业正在进行中,旨在测试已采样的地表区域的下倾延伸区域。沿走向1.6公里的长度中约1.2公里共被施工10-15个近地表的钻孔用以进行测试工作,得到深度在25-75米之间的钒和碱金属富集的成矿带。各钻孔之间的距离大约为150米,将在矿化单位的几何结构得到更好的认识之后被填堵上。

公司的钒矿项目属于旗下一个新的子公司VanSpar矿业公司所有,斯帕顿的许多位于中国的钒矿股权和资产也归VanSpar所有,其中包括仁天项目和附近的郭家坪项目。

作为正在进行的仁天采矿执照和加工厂的尽职调查的一部分,公司已经完成了一个详尽的地表取样工作,并且重新审查了仁天加工厂的运营系统和基础设施。

超过160个的岩屑抓样包含了1.6平方公里采矿执照范围内的大部地表钒矿石单元。之前没有类似的采样记录,也没有实施过用以评估钒富集地层单位的钻探作业。采样覆盖了钒富集区域水平走向1.6公里的大部分区域。钒富集单元大约30米厚,沿西北走向,向东北方向下倾大约10-15度。

得到的最佳的连续性岩屑样本结果为:在一个24米宽的采样区域,钒氧化物平均品位为1.10%。在这一区间,12米宽的区域平均品位为1.31%。该区域得到的最高价值是1米宽的区域平均品位为2%。另外的样本包括:12米宽的区域品位为0.75%,以及7米宽的区域品位为0.73%。

同时包括矿化和非矿化区域在内的所有的162个样本集合中,钒氧化物平均含量为0.43%,大约有20%的样本超过了1%。

最令人感兴趣的是钒矿化带中伴生大量的铜、锌和银。这些是在进行质量控制工作而完成的许多多元素和个体分析中被发现的。

高品位的钒矿中也伴生大量的银。包括:1米的岩屑样本中,银品位为39.9克/吨且钒氧化物品位为1.66%,银品位为23.1克/吨且钒氧化物品位为1.21%,银品位为18.2克/吨且钒氧化物品位为1.20%。
