Ini dia Beutong Copper Project
The Beutong Project is located in Indonesia on the island of Sumatra,
approximately 180 kilometres south east of Banda Aceh, the capital of
Aceh province. The tenement covers an area of 100km2 and is held under
an exploration license (IUP), granted according to Indonesian mining
law. The forestry classification in the Beutong prospect area allows for
exploration and open pit mining.
Access to the Beutong Project is via the town of Meulaboh, 55kms to the south east of Beutong, via a sealed road.
TR Metals has an agreement with PT Emas Mineral Murni (EMM) to earn up to an 80% interest in the Beutong Project. TR Metals currently holds a 20% equity interest in the project.
The geological setting of the region is complex. The Beutong porphyry copper (+ gold, molybdenum)deposit lies along the western tip of the Sunda Banda Arc on a north-west fault splay that parallels the major Trans-Sumatran fault. Major deposits such as Batu Hijau (13Moz Au and 6Mt Cu), Tujuh Bukit (14Moz Au and 4Mt Cu), Martabe (>8 Moz Au) and Miwah (>2 Moz Au) occur along the same structural setting .

The Beutong Project is a large copper-gold-molybdenum system, with at least three styles of mineralisation recognised to date. Porphyry copper-gold mineralisation outcrops over 2,200 x 300m, where previous explorers identified the “East Porphyry” and “West Porphyry” systems,believed to be a single large system.
Approximately 300m north of the porphyry systems is skarn hosted copper-gold mineralisation that outcrops over a strike length of at least 1,000mtrs and is up to 50mtrs wide. High sulphidation copper-gold mineralisation has been identified west and south of the east porphyry, but is relatively untested and dimensions are currently unknown.

Exploration
Drilling by previous explorers encountered broad
zones of moderate to high grade copper-gold-silver-molybdenum
mineralisation, including porphyry style mineralisation of 150mtrs @
1.50% CuEq and skarn style mineralisation of 33mtrs @ 3.14% CuEq and
107.9mtrs @ 1.39% CuEq. Molybdenum values are locally very high in the
porphyry system with intervals up to 12mtrs @ 0.13% Mo reported. TR
Metals is systematically defining the high grade mineralisation
(porphyry or skarn), and each remains open in all directions and at
depth.
TR Metals has completed 4,150m of drilling focused on infill and extension of the higher grade central core of the porphyry deposit and on defining and expanding skarn hosted high grade copper-gold mineralisation to the north. High grade copper mineralisation has been confirmed to 450mtrs RL (bottom of targeted resource shell) on section lines TRM-BEU0800 and 0900, with recent results including:

- 343mtrs @ 1.22% CuEq from 7mtrs in DDH BEU0800-02
- 374.2mtrs @ 1.01% CuEq from 5mtrs DDH BEU0900-01
A deep drill hole has confirmed that strong copper mineralisation
continues to depth below the current estimated resource envelope, and
with a notable increase in silver, molybdenum and locally gold. Deep
hole BEU0900-01 returned 160m (549–709mtrs) grading 1.00% CuEq (0.75%
Cu, 0.19 g/t Au and 7.07 g/t Ag and 248 ppm Mo). To date, all drill
holes have intersected broad zones of high grade Cu, Au, Ag and Mo
mineralisation, and significant assays are listed in Table 1.
A resource of +100Mt is being targeted by end of the third quarter, 2012.
Figure 8: Cross section TRM-BEU0800, showing the high grade porphyry envelope core and high grade skarn mineralisation to the north
Drilling at the East Porphyry has confirmed covellite – digenite dominated copper mineralisation from surface (925m RL) down to the 450m RL, hosted in a diorite porphyry and diatreme breccia system (Figure 8). Deep drilling has demonstrated the high grade core of the East Porphyry may be significantly larger than estimated, with strongly mineralized porphyry and diatreme breccias continuing to depth. S ignificant assays from the east porphyry and skarn drilling are listed in Table 1. It should be noted that sulphide and alteration zonations observed in the East Porphyry are comparable to those reported for the Wafi – Golpu porphyry/diatreme system in Papua New Guinea.

The Beutong Mineralized System comprises porphyry copper (gold-molybdenum) and associated skarn copper–gold styles of mineralization. The majority of holes drilled by previous explorers tested only the upper levels of both the porphyry and skarn, and TR Metals drilling has confirmed broad zones of economic grade copper–gold mineralization continues to much deeper levels of the system (i.e. >1% CuEq). TR Metals considers Beutong to be a high quality porphyry copper-gold project and is aiming to rapidly delineate a medium sized copper–gold resource at the East Porphyry that can be rapidly advanced through to feasibility study stage. This will be followed by a more extensive drilling campaign at the West Porphyry, which is expected to delineate a much larger copper–gold resource (with associated silver and molybdenum credits).
