Canatuan Mine

The Canatuan mine is located in the province of Zamboanga del Norte in the Philippines. Small scale gold panning in the area was first recorded in the 1980s, and by the 1990s prospectors had discovered significant gold deposits. The mine is an open pit operation extracting gold, silver, copper, and zinc. It began commercial operations in 2009 under ownership of TVI Pacific, with an annual production of around 100,000 ounces of gold and 1,700 ounces of silver from its oxide deposits from 2004-2008. Rehabilitation and environmental management efforts at the mine focus on water management, tailings containment, and reforestation activities.

Canatuan mine

Location

- located in the province of Zamboanga del Norte, Philippines.

Mining History

- Gold panning activity in the Canatuan Creek area was first recorded in the mid

1980s.

- In 1990 prospectors discovered an extensive field of gold-bearing boulders and

the first test pit was sunk that year.

- By 1994, the area was being worked by nearly 1,500 small scale miners.

- In 1994 TVI Pacific reached an option agreement with the initial prospectors and

continued extensive exploration.

- In 1995 a pre-feasibility study was carried out, and in 1996 a two feasibility

studies were completed.

- In 2003 a new feasibility assessment was carried out, which recommended

further infill drilling to better define the deposit, and this drilling was carried out in

2004. Two more feasibility studies were carried out in 2004 and 2006.

- In April 2008 operations to mine and recover gold and silver from the oxide layer

were concluded, and the related ore processing facilities were being converted

to process the sulphide deposit.

- The sulphide deposit mining and processing achieved commercial operations on

March 1, 2009.

- In January 2010 TVI announced a joint venture with the Philippine-based

company DACON.

Ore Type

- gold, silver, copper and zinc.


Separation Process

- Canatuan sulphide open pit operation is designed such that the water from the

pit (acid mine drainage) flows to the lowest elevation and is impounded at the

tailings dam. This is unlike the typical open pit operations where a burrow will be

dug out from the mountain and mechanical dewatering systems are applied.

Annual Production

- Gossan phase gold and silver operation (now closed) from 2004 to 2008 TVIRD

operated an open pit mine, milling and processing operation producing gold and

silver doré from the Gossan ore deposit. Over that period the operation

produced in the order of 100,000 oz of gold (Au) and 1,700 oz of silver (Ag).

- Sulphide phase copper and zinc production capacity is 1,850 tonnes per day of

ore, with a request to increase this to 2,500 tonnes per day. Total material moved

has averaged 3,800 tonnes per day and will peak at 6,700 tonnes per day in

2012 . The operating fleet of the mine includes 54 haul trucks, 9 excavators, six

bulldozers, and four loaders.

Company Existing Social Environment and Rehabilitation Project

- The principal control activities related to the current operation are those of water

management (runoff and process water), and water monitoring tailings

management (permanent containment of the non-mineral material that is

physically separated from the ore in the process plant).

- TVIRD's annual activities include progressive rehabilitation with the primary focus

on slope stabilization and erosion control, revegetation and reforestation

activities including soil conditioning and sediment control.
