Panoro Minerals Ltd. announces Column Leaching Test Results for Antilla Copper Project, Peru
August 07 2018 - 8:20AM
Panoro Minerals Ltd. (TSXV: PML, Lima: PML, Frankfurt: PZM)
(“Panoro”, the “Company”) Panoro is pleased to announce
results of column leach testing of the supergene secondary
sulphides at the 100% owned Antilla Copper Project.
The column leach testing indicates that copper
extractions of up to 77% are potentially achievable from the
secondary sulphides. The PEA results announced in May 2018
included an estimated 72.5% copper recovery over a 200 day span
from the secondary sulphides. The PEA mine plan included 117
million tonnes of secondary sulphide or 98% of the feed to the heap
leach pad. The column testwork was initiated early in 2018
while the PEA was underway but final results were not available
until July 2018. The recoveries estimated for the PEA were
derived from bottle roll and mineralogic testwork available at the
time of the completion of the PEA. Based on the foregoing 75%
Cu extraction in 200 days is an appropriate figure to use for PEA
level studies.
“We are pleased that the column leach tests
indicate the potential for recoveries higher than estimated by the
bottle roll tests included in the PEA estimate. A potential
increase in recoveries will further enhance the economics of this
already robust project. Additional testing is planned as part
of feasibility studies for the Antilla Project. The Company
is currently reviewing strategic alternatives to advance the
Antilla Project into feasibility studies, permitting and
development,” stated Luquman Shaheen, President & CEO of Panoro
Minerals.
The Antilla Project process included in the 2018
PEA is based on leaching secondary sulphides. This led to a column
leach program, together with associated mineralogical and bottle
roll leach testwork, being implemented during March 2018 at Aminpro
Laboratories, an ISO 9001 and 14001 Laboratory based in Lima, Peru.
All works were designed and supervised by Andrew Carter, General
Manager of Mining and Minerals of Tetra Tech Inc., UK Office.
About Panoro
Panoro Minerals is a uniquely positioned Peru
focused copper exploration and development company. The
Company is advancing its flagship project, Cotabambas
Copper-Gold-Silver Project and its Antilla Copper-Molybdenum
Project, both located in the strategically important area of
southern Peru. The Company is well financed to expand, enhance and
advance its projects in the region where infrastructure such as
railway, roads, ports, water supply, power generation and
transmission are readily available and expanding quickly. The
region boasts the recent investment of over US$15 billion into the
construction or expansion of four large open pit copper mines.
Since 2007, the Company has completed over
80,000 meters of exploration drilling at these two key projects
leading to substantial increases in the mineral resource base for
each, as summarized in the table below.

The PEAs are considered preliminary in nature
and include Inferred Mineral Resources that are considered too
speculative to have the economic considerations applied that would
enable classification as Mineral Reserves. There is no certainty
that the conclusions within the updated PEA will be realized.
Mineral Resources are not Mineral Reserves and do not have
demonstrated economic viability.
