Minera Alamos completes phase 2 of test heap leaching at

Santana gold project in Sonora, Mexico with further positive

results

/CNW/ -

Minera Alamos Inc. ("Minera Alamos" or the "Company") (TSX

VENTURE:MAI)

is pleased to report that it has now completed the second phase of its bulk testing heap-leach activities at its 100% owned

Santana gold project in

Sonora, Mexico

. The Company is now performing a full review of the leaching results as part of if its final project

evaluation prior to making commercial production decisions for the project.

Over the past year, the Company's wholly-owned subsidiary Corex Gold has been conducting continuous bulk heap-leach testing activities at the

Santana gold project in accordance with its current test mining permit. Following the successful completion of an initial phase that utilized coarse

crushing (<3") only, the second phase involved fine crushing (<1.2-5/8') and agglomeration of the same mineralized material prior to leaching.

Ultimate gold recoveries from the second phase were excellent and consistent with those from the first phase of testing.

Approximately 5860g (~190 oz) of gold were recovered from a total of 9000 tonnes of material over a three month leach period – 0.65 g/t of

recovered gold. While the use of fine crushing/agglomeration appears to improve the gold leach kinetics, ultimate recoveries remained similar to

those achieved leaching coarse material.

"The results from the bulk heap leach testing program over the past year have been extremely positive. The operation of the Santana test leaching

facilities provides for a significant de-risking of the project by comparing laboratory scale metallurgical results to those achieved at a bulk scale

under conditions similar to those envisioned for commercial operations." stated

Darren Koningen

, CEO of

Minera Alamos

. "To date, the Company

has tested approximately 35,000 tonnes of mineralized material with ultimate gold recoveries exceeding expectations and appearing to be

consistent over the range of crush sizes tested. This creates an ideal environment for a robust commercial heap leaching operation at the Santana

project site. Once a final data review/optimization is completed, incorporating results from the upcoming drill program announced earlier this

month, the Company expects to target the advancement of Santana as the first commercial mining operation from our portfolio of advanced stage

gold projects."

As done previously, the second carbon shipment from the test facility will be shipped later this week for desorption and precious metals recovery

operations at Metals Research Corporation in Kimberly, Idaho. Final doré is delivered for refining to Cascade Refining Inc. of

Salt Lake City

,

Utah.

Note:

The Company is not basing any production decision on a feasibility study of mineral reserves demonstrating economic and technical viability. Minera Alamos

acknowledges and advises there is increased uncertainty and that there are specific economic and technical risks of failure associated with any production decision. The

Company believes the historic experience and track record of senior management with gold heap leaching and by advancing in careful prudent steps helps ameliorate

possible technical risks.
