Sparton Resources (SRI-V) has intersected significant gold, adding to the resource at the Guanlingpo mine, part of the Luxi project in Yunnan province, southwest China.
Seven holes (totaling about 1,000 metres) have been drilled so far this summer and an eighth is underway.
The first 3 holes were collared 50 metres northwest of (and outside) the Guanlingpo mining lease. Highlights from these holes include an intersection of 2.6 grams gold over a width of 59 metres starting from 26.7 metres down-hole. This intersection contains a 6-metre intercept grading 7 grams gold, 23 metres grading 3 grams gold and 12 metres grading 4.4 grams gold per tonne. This hole was drilled at a 70 angle.
Another hole drilled from the same set-up (but at 50) intersected 33.4 metres grading 2.85 grams gold from 46 metres down-hole. Again this intersection contained several intercepts with higher grades, such as a 5-metre intercept grading 7.52 grams gold (including one metre grading 35 grams gold) and 12.4 metres grading 4.35 grams gold (that includes 2 metres grading 14.75 grams gold and 5.4 metres grading 3.5 grams gold).
Hole 07, drilled 225 metres northeast of the aforementioned holes, intersected 23.8 metres grading 3.24 grams gold. This includes an 8-metre intercept grading 4.43 grams gold and a 5-metre intercept grading 4.24 grams gold. This hole was collared close to the boundary of the open pit, however it is within the mining lease.
Hole 04 was drilled 75 metres northwest of holes 01-03 and intersected anomalous gold grades from 0.3-0.8 gram gold over widths of 3-15 metres. The lower grades intersected in two of the holes may indicate that proximity to the fault is an important factor controlling gold mineralization.
Mineralization at Guanlingpo is associated with the 10-km-long Shangmangyang fault zone. This strikes northeast across the open pit, which is characterized by silicified, altered and stockwork-veined dolomite. The sediments dip 40 northwest. Above the dolomite is a mudstone unit containing local pyrite. This unit hosted the gold mineralization in several holes. Both primary sulphide and oxidized material are present in the pit.
Systematic chip samples were collected in sulphidized sections of the Guanlingpo main pit area. Highlighting this sampling is a 10-metre section grading 3.1 grams gold and a 6-metre section grading 7.9 grams gold. Other sections graded from 0.5-1.24 grams gold over 10-14 metres.
Samples are being prepared and analyzed at an on-site laboratory, which has been inspected by SGS Lakefield Research and duplicate analyses are being done by SGS in Canada.
Samples from the first drill hole have been sent for preliminary metallurgical gold recovery testing to consulting firm Kappes Cassidy and Associates of Reno, Nevada.
Sparton owns an 80% interest in the 250-sq.-km Luxi gold project through the joint venture company Yunnan Sparton Minerals; 20% is held by Yunnan Nuclear Geological Exploration Brigade 201. Sparton also has an option to earn 62% of the deep exploration licence area below the open pit mining licence area.
