G-RESOURCES continues its successful exploration program at the Martabe Gold-Silver Project in North Sumatra. Recent drilling has focused on the potential for expanding the mineral resource estimates with campaigns conducted on extensions to known resources at the Purnama, Barani, Uluala Hulu and Tor Uluala deposits.

Trenching results at Tor Uluala have extended mineralization to the north and confirms that mineralization extends to surface in some areas. Best results from the trenching are 11 metres @ 6.36 grams/tonne gold, including 5 metres @ 8.17 grams/tonne, and 33 metres @ 13.49 grams/tonne, including 14 metres @ 29.2 grams/tonne.

Exploration continues to define extensions to Purnama deposit. Recent work has focused on defining the limit of mineralized zones to the southeast of the current pit and locating depth extensions of Purnama.

G-Resources has received final results of 12 drill holes at Purnama South East deposit with best results being 36.3 metres from 137.2 metres @ 1.14 grams/tonne gold and 28 metres from 129 metres @ 1.24 grams/tonne. This drilling will be incorporated into a new resource estimate to be released in 2015.

The continuation of feeder system depth extensions to Purnama deposit was the result of successful application of a geological model to the exploration program, made possible by the introduction of specially modified diamond drill rigs capable of drilling horizontal holes.

Following the initial results, the horizontal drilling program continued in the second half of 2014 and defined three dimensional continuity of mineralization in these feeder zones. Several wide zones were intersected. Best results are: 66 metres from 207.7 metres @ 1.43 grams/tonne and 25 metres from 319.8 metres @ 1.13 grams/tonne; 11 metres from 132 metres @ 1.36 grams/tonne and 38 metres from 147 metres @ 0.84 grams/tonne; and 49.5 metres from 104.5 metres @ 1.03 grams/tonne.

This work confirms that mineralization extends downwards in some places to at least 100 metres under the current mineral resource block model. An infill drilling program is under way to infill between this new horizontal drilling and the existing resource. This will be completed in 2015, at which point a new resource will be estimated.

Drilling at Barani is targeting the southern extension of the planned Barani South open pit, and extensions at depth. Mineralization outcrops at the surface. To date the mineralization has been extended immediately south of the planned pit by 200 metres. Best results are 15.2 metres from 72.1 metres @ 3.8 grams/tonne and 23.8 metres from 26.5 metres @ 3.8 grams/tonne.

Additional extensions to Uluala Hulu resource have been identified and drilled. An updated estimate was expected by the end of 2014. Best results are 71.8 metres from 56 metres @ 3.30 grams/tonne and 19.2 metres from 12 metres @ 1.20 grams/tonne.
