Maya Gold & Silver Inc. Files Technical Report on Positive PEA at the Zgounder Silver Mine in Morocco

MONTREAL, QUEBEC--(Marketwired - Feb 22, 2018) - Maya Gold & Silver Inc. ("Maya" or the "Corporation") (TSX VENTURE:MYA) is pleased to announce that it has filed on SEDAR a Technical Report in compliance with National Instrument 43-101 (NI 43-101) to support the mineral resources estimates declared on January 8^th and the PEA declared on February 5^th 2018.

This press release confirms the February 5^th disclosure.

The Corporation presents the results of an independent NI 43-101 Preliminary Economic Assessment Study ("PEA") on its Zgounder Silver Mine in Morocco. The mine is owned by Zgounder Millenium Silver Mining S.A. (ZMSM), a Maya 85% owned joint venture with l'Office National des Hydrocarbures et des Mines of the Kingdom of Morocco (15%). The PEA Study, prepared by GoldMinds Geoservices Inc. from Québec City (GMG), is dated January 30^th 2018 and relies on mineral resource estimates reported on January 8^th 2018.

Maya started the first diamond-drilling program at Zgounder in April 2015 and both the diamond drilling programs of 2015 and 2017 allowed Maya to increase the mineral resource estimates of Zgounder. The milling operations began in July 2014 and Maya announced the first silver pour in August 2014 with the production of the 20 silver ingots. Maya has produced a total of 1.35 million ounces of silver at its Zgounder mine as of December 2017.

Highlights of the Zgounder Silver Mine PEA Study:

• A project life of 10 years with the current resources up to 2027;
• ZMSM Internal Rate of Return of 134% and 118% after taxes;
• ZMSM pre-tax Net Present Value of US$215.1M (discounted at 6.5%) at variable silver price from US$17.50 to US$21.50 per ounce with yearly average of US$20.50 per ounce;
• ZMSM after-tax Net Present Value of US$200.2M (discounted at 6.5%) at variable silver price from USD$17.50 to USD21.5 USD per ounce with average of US$20.5 per ounce;
• The extraction of 3.974Mt at 292 g/t Ag for silver production of 33.682M ounces;
• Milling to increase to 500 tpd in 2018 then up to 2020 followed by a 2000 tpd in 2021;
• Production increase to 1.354M ounces per year up to 4.762M ounces of silver per year;
• Total operating cost of US $63.64 per tonne (averaged over the expected mine's life);
• Capex and sustaining capital requirements of US $46.9M
• MAYA Internal Rate of Return of 121% with an NPV of US$209.86M;
• The Zgounder PEA was prepared as combination of underground extraction, open pit extraction of mineralized material as well as reprocessing of old tailings based on the mineral resources reported on January 8, 2018.

Cautionary Statements

The PEA is preliminary in nature and includes the use of inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. Thus, there is no certainty that the results stated in the PEA will be realized. Actual results may vary, perhaps materially. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Additional exploration work is required to increase the quality of the mineral resources.

Message From the President

Noureddine Mokaddem, President of Maya, stated: "These positive results of the PEA are an important milestone reached at the Zgounder silver mine. We are very excited to see such high NPV, a break-even point before taxes of US$10.40/ounce Ag, well positions Zgounder to face severe commodity fluctuations. The financial results outlined in the PEA are highly encouraging, indicating the economic viability of the known resources and supports our belief that Zgounder is a robust project, and has the upward potential in inferred resources to grow into an important silver producer. These results will help Maya continue to scale and achieve its aspirations."

Mineral Resource Used in the PEA

The NI 43-101 PEA Study was based on the undiluted mineral resource estimate prepared by GMG previously reported by Maya on January 8^th, 2018. The table below summarizes the mineral resource estimated by GMG combining forty-eight (48) envelopes and the old tailings.

A cut-off grade of 61.89 g/t was applied for the in-pit mineral resources and a cut-off grade of 125 g/t was applied for the underground mineral resources (just under the pit surface).

The sensitivity analysis suggests that the most sensitive parameters are the head grade, the recovery and the silver price. The project outlook calculation presents a robust positive project even at US$14.35/Oz silver and also shows important NPV with the increase in Metal price.

Operating Costs

The operating costs, also called operating expenditures (Opex), are expressed in USD per tonne processed, and are summarized below. This next Table outlines the costs of the total project.

Operating Costs
Items	Cost	Cost
	US	US/t milled
Waste development cost	$102,074,242	$20.72
Mineralized Material production cost	$51,842,142	$10.52
Mineralized Material process cost	$95,507,510	$19.39

Royalty & Management fees (incl. NPI)	$40,765,601	$8.27
Total	$313,514,993	$63.63

Note: The internal shaft, main ramp with all major underground developments of the mine down to 1620m level are in the Capex sustaining capital. Provision for additional underground development is taken into account with a 20% waste development of mineralized material mined at year 2021 as it is currently at 10%.

Capital Costs

The breakdown of the surface, mill and underground remaining capital cost expenditures (Capex) and sustaining capital to materialize the study is summarized in the following table. It is important to realize that the Zgounder project capital costs for the 500 tpd mill has already been paid with the mine revenues.

The sensitivity analysis suggests that the remaining capital cost has low impact on the economical results.

It is important to mention that operating costs are based on existing real cost adapted to up scaling scenarios. Moreover, the mill capital costs are based on real effective quotes received from Xinhai based in China. The 500 tpd mill is already on site and is being installed.

In addition to the capital cost needed of US $5,000,000 initially, there is an estimated amount of US $41,900,000 required for the sustaining capital included in the cash flow. No contingency on the Capex has been added, as it is a preliminary economic assessment with a +/- 30% precision.

The Zgounder Cash Flow after tax is positive every year from its own revenues except for year three, which will require financing, and with a payback of one year. The 500 tpd mill is uphill near the existing base camp, while the proposed new 2000 tpd mill should be installed south of the 2000m level entrance and the existing 200 tpd mill.

Mining

The Zgounder deposit assumes the processing of an average of 340 tpd for the first year (half at 187.5 tpd and half at 500 tpd), with an envisioned expansion to 500 tpd forecasted for two years and 2000 tpd for the remaining seven years of production.

The Zgounder deposit is located in competent rock and has a steep overall dip, making it easily mined using free falling methods. It is recommended to use the open long-hole mining method with sub-levels for the proposed new mining sites.

It is proposed to excavate a main ramp to connect all existing levels to the East above the 2,000m up to 2,100m level. Continued ramp access to the 1,800m level below the 2000m level and reach out the develop levels down to 1,925m and the future levels down to 1,800m; this will facilitate the development and also the transportation of backfill when required. Above 2,100 m elevation, the levels are accessible by adits. As the mine has previously been in production, few new developments are required above 2000m. The total of additional development required is estimated at 20% of mineralized material tonnage with an average of 3.0m linear meters per working day. There is a provision in the Capex (sustaining capital) for an average of 6.0m linear per working day, including the ramp (3.4m x 4m section), for a total of 4,691 meters for the major access and a 315m internal shaft for the life of mine (LOM).

The current processing plant was built to process 200 metric tons per day, assuming 350 working days per year, amounting to 70,000 tonnes per year. With the implementation of the new 500 tpd, mill assuming 350 working days per year, amounting to 175,500 tonnes a year, the feed would come from the underground mine above the 2000m level. Subsequently with the implementation of the 2000 tpd mill, mining and mill feed should come from the surface, underground and the ancient tailings in a proportion of 45%, 42% and 13% respectively. The scheduled tonnage for the 2000 tpd from surface is 900 tonnes, 840 tonnes from underground and 260 tonnes from the old tailings. This has been applied to the ratio of available resources and optimization has not been done.

The surface extraction should use drill, blast, load, haul to crusher and/or ore pass of the existing Alimak. A fleet was initially selected and the management of ZMSM prefers to use national mining contractors to reduce the Capex burden. As well, underground mining equipment was initially selected as a fleet, as the mine is actually mining contractors, the Corporation wishes to pursue that path and equipment list elaborated by Goldminds should be used as reference for the equivalence. With the present total mineralized material being in the order of 4Mt, the mine life would be 10 years with the upgrade to 500 tpd and the 2000tpd. The mineralized material available is 1.681Mt at 331 g/t from UG, 1.79Mt at 300 g/t from potential quarry and 500,000 tonnes at 132 g/t Ag from the old tailings. Material at the surface is pit constrained.

According to the historical and the current mine production, the mining dilution is 10% and the mining recovery is 97%. The 10% mining dilution is applied up to year 2020 and afterward 30% as it represents the 10% from underground and an expected 50% dilution in the pit. These values are applied in the PEA Study. A dilution grade of 50 g/t Ag to the mill feed grade is applied.

The Zgounder mine is accessible from adits on each main level, offering the advantage of straightforward dewatering and good natural air circulation from surface to the 2000m Level. Existing levels down to 1925m should be used in the redevelopment below the 2000m main level.

Metallurgy and Processing

Actual mill operation is about 185 tpd, the feed grade approximately 330 g/t Ag, and the silver recovery is in the 87% range. The intent of Maya is to gradually increase the Zgounder mill feed rate from +/- 200 tonnes per day to 2,000 tonnes per day.

• First step is to increase the mill feed rate to 500 tpd (2018 -2020)
• Second step is to increase the mill feed rate to 2,000 tpd (2021 -2027)

The object of this chapter of the PEA is to describe in broad detail the mill operation at 500 and 2,000 tonnes per day. If this PEA proves successful, the 500 tpd operation will be addressed later in a future prefeasibility study.

The 500 tpd process plant is designed to recover the silver by a gravity-flotation process followed by the cyanide leaching of the gravity and the flotation concentrates in two different mills. The "upper" mill, designed by Yantai Xinhai Mining Research & Design Co., Ltd. (Xinhai), which will be located some 1.5 km from the actual mill will incorporate the following sections: run of mine mineralized material storage, a three stage crushing plant, two 500 tonne fine mineralized material bins, a two stage grinding bay integrating gravity, a flotation section followed by gravity and flotation concentrates thickening and regrinding spaces.

The "lower" mill (actual Zgounder mill), will essentially remain the same as it is now except for the removal of the two small ball mills and changing of the present clarifier by four filter-presses. The "lower" mill will be fed by gravity from the gravity-flotation concentrates (cyclones O/F) coming from the "upper" mill. The expected mill recovery based on provided met test is set to 80%.

For the 2,000 tonnes per day operation (2021 - 2027), ZMSM will need a complete new mill. Mill feed averaging 233 g/t (at least for years 2021 to 2024) will come from 3 different locations. Around 45% will come from the open pit, 12% from the old tailings and the other 43% from deep underground-mineralized sectors. To have a smooth and steady operation and to avoid large variations in feed grade and quality, the design criteria for the processing plant is based on a continuous and homogenous feed rate from all sources. The 2,000 tpd processing plant will be designed to recover the silver mainly by cyanide leaching followed by a CIP (carbon in pulp) process. The mill tentatively proposed by Goldminds Geoservices Inc. (GMG) should be located some 250m from the actual 200 tpd mill and will incorporate the following sections: run of mine mineralized material storage, a one stage crushing plant, two fine mineralized material bins, a two stage grinding bay integrating gravity, cyanide leaching followed by carbon adsorption, carbon elution and finally refining. The expected mill recovery based on provided met test with a complete new mill is set to 90%. Additional metallurgical testing is required to validate all parameters of the proposed process.

Mill rejects should undergo cyanide destruction before disposal into the tailings pond or will be naturally destroyed in the pond. GMG is of the opinion that the new conceptual tailings pond has the capacity to store the whole mine life production of this PEA, that is to say during the next ten years of operation. Additional work will need to be done to validate the conceptual design.

Supernatant from the tailings ponds will flow by gravity to a small polishing pond, where it will be treated if necessary, and approximately 80% will be pumped back to the mill. The other 20%, free of any cyanide, will be discharged in the valley connected to the small Zgounder River.

Infrastructure

The energy is coming from a new power line rating 22 KV, having a power of 2500 KVA, is expected to be powerful enough for the milling operation of the 500 tpd. Subsequently, for the 2000 tpd mill, a new line will have to be installed from Taliouine and preliminary discussions with the Office National of Energy (ONE) set the total Capex to US3.5 million.

A new water line will have to be installed for the 2000 tpd mill upgrade and there is a provision in the Capex for this. As well, the existing tailings will be reinforced and modified to accommodate the whole mine life of the PEA. A polishing pond with water containment of 450,000 cubic meter is planned to assist in the management of recycle water. Provision for a water treatment plant near the polishing pond has been done.

A provision in the Capex exists for the expansion of the existing accommodation camp will be required to lodge the additional workforce (the staff and mining contractors).
