A second ball mill for the mine expansion has passed through all upgrades and inspections and is now on

site and placed into the supporting structure (see photo). This second mill has a larger capacity and once

commissioned the mine’s installed capacity will be 1,250 tpd. Ancillary equipment (cyclones, pumps etc. )

will be delivered to site before mid -

October. Testing of the new mill is

planned for late -November and , if

successful, ramp-up will commence

shortly after.

The flotation and concentrate filtration

circuits already have an installed capacity

of 1,000 tpd.

A second tailings filter press, with a

nominal capacity of 500 tpd, will be

transported to site within a week . The

foundations for this press are completed.

The third (back-up) tailings filter press has

been secured and is undergoing inspections and refurbishments prior to shipping to site.

Construction of the second stage of the tailings embankment is currently 56% complete and progressing

well.

Mike Struthers, CEO, commented: “The team at Tahuehueto, including our contractors and senior

management, have done a great job in maintaining construction progress, pushing towards our 1,000 tpd

goal, and we are on track to achieve this by year-end. We plan to be testing the second mill by late-

November, and if successful we should be able to start ramping up to 1,000 tpd shortl y afterwards. We

are very close now to delivering Tahuehueto as the next, new profitable gold mine in Mexico. ”

Cautionary Note Regarding Production Decisions and Forward-Looking Statements

It should be noted that Luca declared commercial production at Campo Morado prior to completing a feasibility study

of mineral reserves demons trating economic and technical viability. Accordingly, readers should be cautioned that

Luca’s production decision has been made without a comprehensive feasibility study of established reserves such that

there is greater risk and uncertainty as to future economic results from the Campo Morado mine and a higher technical

risk of failure than would be the case if a feasibility study were completed and relied upon to make a production decision.

Luca has completed a preliminary economic assessment (“PEA”) mining study on the Campo Morado mine that

provides a conceptual life of mine plan and a preliminary economic analysis based on the previously identified mineral

resources (see News Release dated November 8, 2017, and April 4,2018).

Statements contained in this news release that are not historical facts are “forward -looking information” or “forward -

looking statements” (collectively, “Forward-Looking Information”) within the meaning of applicable Canadian securities

of mining operations at Campo Morado; and other possible events, conditions or financial performance that are based

on assumptions about future economic conditions and courses of action; the timing and costs of future activities on the

processing activities, and timing for processing at its own mineral processing facility on the Tahuehueto project site. In

certain cases, Forward -Looking Information can be identified using words and phrases such as “plans,” “expects,”

“scheduled,” “estimates,” “forecasts,” “intends,” “anticipates” or variations of such words and phrases. In pre paring

the Forward -Looking Information in this news release, the Company has applied several material assumptions,

including, but not limited to, that the current exploration, development, environmental and other objectives concerning

the Campo Morado Mine and the Tahuehueto Project can be achieved; that recommencement of operations at Campo

Morado will proceed as planned; the continuity of the price of gold and other metals, economic and political conditions,

and operations. Forward-Looking Information involves known and unknown risks, uncertainties and other factors which
