Arc: Drilling at Trenggalek gold project suspended for evaluation, to resume in July
Tuesday, June 21 2016 - 02:06 AM WIB
ASX-listed Arc Exploration Limited announced that a new phase of diamond drilling at Trenggalek gold and copper, in East Java, which started in early February of this year, has been stopped at the commencement of the Islamic fasting month and the results received to date will be evaluated during this period. Drilling may recommence in July 2016.
The company said in a statement that a total of 2745 meters in 20 holes has been completed to-date in this latest drilling phase. These holes test for mineralized extensions to within the large Sentul and Buluroto epithermal gold veins, which were previously tested with scout diamond drilling by ARX in 2010/11.
The company provides the following explanation in the statement.
Gold results for the first five holes in this latest drilling program were reported in an earlier announcement. This announcement reports the gold results for the next eleven holes; STDH03 to STDH09 (Sentul) and BRDH03 to BRDH06 (Buluroto)
The most significant gold intercepts from the latest results are:
? 1.80 m at 3.8 g/t Au from 38.2 m down-hole in STDH03 on Sentul East vein
? 5.15 m at 6.89 g/t Au from 50.55 m down-hole in STDH04 on Sentul East vein
? 1.75 m at 1.6 g/t Au from 104.0 m down-hole in STDH08 on Sentul West vein
The two gold intercepts returned on the Sentul East vein, STDH03 and STDH04, were obtained between previous lines of drilling completed by ARX in 2010. These holes confirm the presence of shallow gold mineralization within a segment of the East Sentul vein, having about 150-meter strike-length and at less than 50 m below surface. The true-width of the mineralized intersections is estimated to vary from 1 to 3.5 metres within the mineralised segment. The gold mineralization is believed to be open at depth.
Narrow low-grade gold (<1 g/t Au) intercepts were returned from the Buluroto vein. Recent drilling here was done at the northern end of the northeast-trending vein. This is less prospective than the southern end of the vein where previous drilling by ARX returned significant gold intercepts in mineralized breccia such as 13.75 m at 3.19 g/t Au & 60 g/t Ag.
Gold results for the remaining holes completed in this latest drilling program (STDH10 to STDH12) are awaited. These are expected to be received soon and will be reported accordingly. A low-level of field activity is currently in progress during the Islamic fasting month at Trenggalek.
