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

The Balabag NI 43-101 technical report dated June 23, 2012, and entitled
“NI 43-101 Technical Report on the Balabag Gold Project, Zamboanga
Province, Philippines” is available on SEDAR at www.sedar.com and on TVI’s website at www.tvipacific.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.
