TORONTO (miningweekly.com) – Exploration junior East Asia Minerals on Monday reported positive results from its Phase 1 drilling programme at the company's Sangihe project, in Indonesia.

East Asia Minerals VP of exploration Frank Rocca said the results were in line with the resources and grades identified in the National Instrument (NI) 43-101 technical report, completed in 2009.

"The latest drilling results identified another significant mineralised intercept to the north-west with hole BOD093, which may enable us to extend the current resource," Rocca said.

The exploration programme, which entailed 4 600 m of drilling, was divided between the Binebase zone extension that consists of 12 holes totalling 1 800 m, the Bawone zone extension consisting of 12 holes totalling 1 800 m and ten scout holes at the Kupa and Taware areas, totalling 1 000 m.

The Phase 1 drilling programme at Bawone resulted in the expansion of the Bawone resource to the north-west with drill hole BOD093. This hole contained a significant intercept measuring 20 m in length from 73.7 m in depth, and an average grade of 1.06 g/t of gold and 0.43% copper.

The intercept included a 3 m interval from 76.7 m in depth with an average gold and copper grade of 1.59 g/t of gold and more than 1% copper. This intercept also had a 2 m interval from 80.7 m with an average grade of 2.59 g/t of gold and 0.44% copper.

The company added that the scout hole drilling in the Taware valley had been successful with four of the ten drill holes intercepting targeted mineralised quartz veins.

A significant intercept occurred from drill hole TAD006 that intercepted a 0.9-m-wide vein with an average gold grade of 14.6 g/t at a depth of 45.25 m.

TAD006 also contained a second significant intercept from a down hole with depth of 101.9 m measuring 3 m wide, with a gold grade average of 1.38 g/t.

Taware drill hole TAD005 contained two significant intercepts. The first at a down-hole depth of 53.4 m, with a 0.8 m breccia zone, had a gold grade average of 2.12 g/t and  a copper grade average of 0.12%.

The second, at a down-hole depth of 138.3 m and 0.6 m wide, had an average grade of 2.09 g/t gold and 0.06% copper.

Taware drill hole TAD004 also contains two significant intercepts, with the first intercept containing an average gold grade of 1.92 g/t, at a depth of 30.4 m and 1 m wide. The second, with a length of 0.8 m at a down hole depth of 34.4 m, had a gold grade average of 1.12 g/t.

Drill hole TAD009 contained one significant intercept at a down-hole depth of 36 m with a 0.5-m-wide breccia zone that had an average grade of 2.32 g/t gold and 0.04% copper.

"The results further demonstrate the potential at Sangihe to increase the existing mineral resource. The Phase 1 drilling programme will be complete by April 15, after which we are moving to drill other prospective areas at Sangihe and start metallurgical studies to consider processing options,” CEO Ed Rochette said.

The second phase of drilling, comprising of 10 000 m, was planned to start in the second quarter of this year. The objective of Phase 2 would be to identify resource extensions and definitions at Binebase, Bawone and Taware.

The company would also drill scout holes to test for extensions from Bawone to Salurlang. Further scout holes were planned for the Kuring and Kupa valley prospects. Kuring and Kupa were known to contain high-grade veins and have extensive artisanal mining activity. Trenching samples retrieved by the company from Kupa had been assayed at 30 g/t of gold.

The Sangihe gold/copper project is located on the island of Sangihe off the northern coast of Sulawesi, in Indonesia. Sangihe has an existing NI 43-101 compliant inferred mineral resource of 27.3-million tonnes averaging 0.95 g/t of gold and 13.58 g/t of silver for 836 718 oz gold and 11.92-million ounces of silver at a 0.25 g/t gold cutoff.

The company's strategy was to first develop the smaller Sangihe deposit, before turning to its flagship Miwah project, in the Aceh province of northern Sumatra.
