TVI Pacific Reports Pilot Plant Metallurgical Test Work Results For Its Balabag Gold-Silver Project, Philippines

June 26, 2013


Initial Results Confirm Balabag Deposit Highly Amenable To Leaching

  • Gold and silver recoveries average 93% and 90%, respectively
  • Demonstrated effectiveness of carbon in leach circuit ("CIL")
  • Amenability of CIL over other processing could translate into lower capex
  • Pilot Plant testing continues to focus on optimizing process efficiencies

CALGARY, June 26, 2013 /CNW/ - TVI Pacific Inc. (TSX: TVI) (OTCQX: TVIPF) ("TVI" or the "Company") announced today that its Philippine operating affiliate, TVIRD has established a pilot plant at its nearby Canatuan mine site to carry out metallurgical test work on samples of the different  types of mineralization at Balabag, the initial results of which are reported herein. The establishment of a pilot plant marks another key step forward for the Balabag project, located approximately 75 kilometres east-northeast of TVI's Canatuan copper-zinc mine on the island of Mindanao, Philippines.

The principal objectives of the pilot plant test work are to confirm the results obtained in previous laboratory cyanide leaching tests, optimize the metallurgical processing under an environment that more closely resembles actual operations, provide design parameters for engineering, and to start training personnel in operations and metallurgical process control.

Initial results from the first 30 tonnes of sample material grading 4.8 g/t Au and 212 g/t Ag indicated average overall recoveries of 93% for gold and 90% for silver after 36 hours leach time (Figure 1). The sample material analysed represents different types of vein mineralization distributed throughout the deposit. The results to date validate Balabag test material's amenability to leaching as determined from prior laboratory scale tests.  Results also demonstrate the effectiveness of carbon-in-leach ("CIL") over both carbon-in-pulp ("CIP") and Merrill-Crowe recovery processes in processing the test material.

The one metric ton per day pilot plant initially had been operated for 21 days simulating CIP plant operations. After some reconfiguration in the circuit, it was operated for three days simulating actual CIL plant conditions.  The amenability of CIL over CIP processing could translate into a lower capex due to shorter leach times and elimination of the unit operations associated with the Merrill-Crowe section of the planned plant. Pilot test work will continue to produce sufficient loaded carbon for design purposes while evaluating variabilities of potential ore grades and further optimizing the process efficiencies.

"These initial metallurgical test work results are very encouraging," said Cliff James , Chairman and President of TVI Pacific Inc.  "Confirmation of metal recoveries in this larger-scale pilot plant will help establish the recoveries of gold and silver that can be achieved in a commercial process."

The results from this test work will be incorporated into the detailed planning for the construction of the plant, which is expected to commence as soon as an Environmental Clearance Certificate (ECC) is granted by the Environmental Management Bureau and approval is received of the Declaration of Mining Project Feasibility, by the Philippine Mines and Geosciences Bureau of the Department of the Environment and Natural Resources.

About the Balabag Project

The Balabag epithermal gold and silver project is located within an area covering approximately 52 square kilometres (20 square miles) and is situated approximately 75 kilometres (47 miles) east-northeast of TVI's Canatuan mine.

The Balabag NI 43-101 technical report dated June 23, 2012, and entitled "NI 43-101 Technical Report on the Balabag Gold ProjectZamboanga Province, Philippines" is available on SEDAR at www.sedar.com and on TVI's website at tvi2014.q4web.com.  The technical report, which incorporates results of drilling completed to the end of June 2011, provides estimates of an indicated mineral resource of 1.78 million tonnes averaging 2.34 grams per tonne of gold and 72.3 grams per tonne of silver containing 134,262 ounces of gold and 4,148,196 ounces of silver.  The Company continues to conduct exploration work with the goal of expanding the resource.
