EAminerals project in Takengon



Takengon East Asia Minerals Corporation announced on February 26, 2007 that it has acquired a 75% interest in the Takengon property which covers approximately 19,000 hectares in Aceh Province, North Sumatra, the most under-explored part of the highly prospective Indonesian archipelago. Under the terms of the joint venture agreement East Asia will initially own a 75% interest in the project with no annual payments or minimum work commitments. The Takengon property encompasses the large, drill ready Collins epithermal gold prospect, a low sulphidation mineralized system associated with an elliptical magnetic feature, a NE-SW trending fault system, and indicative alteration. The mineralization consists of gold-bearing vein swarms and stockwork covering at least 400 by 800 metres. Of particular interest is detailed induced polarization data which suggests that the epithermal veins coalesce below the surface. Assays from several historic channel samples in the veins returned up to 11 ppm gold over 5 metres, along with elevated copper, lead and zinc. In addition to the Collins epithermal gold prospect, the Takengon tenement hosts three other known interesting prospects, identified by historic sampling. These include an outcrop of supergene enriched copper porphyry material immediately adjacent to the Collins prospect containing 2.58% copper and significant elevated gold; a gold-copper skarn mineralization zone returning up to 1 ppm gold and 1240 ppm copper; and another porphyry style mineralization zone just south of the Collins prospect where quartz vein stockworks contain visible chalcopyrite.Initial exploration work at Collins was completed during 1998. Drill targets were selected at that stage but were not drilled due to external issues. East Asia Minerals plans to re-establish these drill pads with minor compilation, confirmatory sampling and mapping, and then begin drilling.

EAminerals project in Tangse


TangsePrevious limited drilling by CRA (Conzinc RioTinto Australia) in the 1980s at Tangse outlined a large porphyry copper-molybdenum deposit containing a coherent zone of copper-molybdenum mineralization five kilometres long and one to two kilometres wide. Historical order of magnitude estimates (non-NI 43-101 compliant) are at least 600 million tonnes (Mt) of lower grade material, including a higher grade zone of 30 Mt with grades between 0.3 and 0.8% copper (Cu), and 0.02 to 0.03% molybdenum (Mo) (van Leeuwen et al, 1987). The Tangse porphyry system has been subjected to widespread supergene enrichment. This is most prevalent in the higher grade, hypogene portion of the deposit where the primary copper grade has reportedly been upgraded by a factor of 1.5 to 3, to grades in excess of 1% copper. EAS exploration will initially focus on this enriched zone. The Tangse project has excellent logistics, and is located only 100 kilometres to the southeast of the Provincial capital of Banda Aceh. It is adjacent to a main regional highway and the power grid.Referencesvan Leeuwen, T.M., Taylor, R.P., and Hutagalung, J., 1987, The geology of the Tangse porphyry copper-molybdenum prospect, Aceh, Indonesia: Economic Geology, v. 82, 27-42

Miwah is a high-level, high sulphidation epithermal gold prospect. The Miwah Gold Prospect was partially defined by approximately 3,000 metres of drilling in eleven holes by a previous explorer in 1997. All holes drilled during this program intersected significant alteration and mineralization with intercepts including 71 metres of 1.4 g/t gold and 58 metres of 1.1 g/t gold. The previous explorer suggested potential for 100 Mt at 1.1 to 1.2 g/t gold, however a review of the historical data indicates that early drilling was parallel to higher grade (greater than 5 g/t gold) structures at surface. Hence, in addition to greater mineralized tonnage, significantly higher overall grades are anticipated from better geological understanding, results of the Company's detailed sampling, and properly oriented drill holes.Based on the Company's work Miwah is resolving into two components; a large 1,200 metre long, 300 to 400 metre wide, approximately 200 metre thick tabular zone; and vertical diatreme breccia feeder zones that are beneath and cut through this. Within the tabular zone East Asia has over 2,000 metres of rock sawn channel samples which average 1.2 g/t gold (see summary table below). Ongoing sampling verified the Company's confidence that higher overall gold grades can be achieved due to the presence of multiple high grade rock sawn channel samples throughout the strike, including 4.11 g/t gold over 200 metres at the eastern part of the gold zone, and 4.35 g/t gold over 27 metres at the western part. Recent drilling has supported this. In addition to the tabular zone the Company has begun to characterize some of the diatreme breccia feeder zones, with rock sawn channel samples including 83.59 g/t gold over 24 metres and 20.14 g/t gold over 12 metres. Recent drilling has supported this. These feeder zones have great potential to develop into substantial tonnages of higher grade gold mineralization in an area adjacent to the Main Miwah Gold Zone.The Miwah Property is in a very similar volcanic setting to the Martabe gold-silver deposit, also located in North Sumatra (Purnama and Baskara resources: 127.8 million tonnes at 1.4 g/t gold (5.5 million ounces gold) and 15 g/t silver (60 million ounces silver), and the alteration system is of a comparable size. Miwah also exhibits a likeness to the size, style and geometry of the alteration system developed at the Pierina gold deposit in Peru (67.7 Mt grading 2.98 g/t gold and 22 g/t silver, giving a total 6.49 million ounces gold and 47.9 million ounces silver)*.EAS is currently drilling at Miwah (see drill summary below). In September 2009 EAS announced that based on consistent strong gold results across the mineralized body diamond drilling will continue uninterrupted for approximately 45 holes to gather the information required to complete a NI43-101 resource estimate.
