VANCOUVER, BRITISH COLUMBIA--(Marketwired - March 31, 2017) - FIRST MAJESTIC SILVER CORP. (the "Company" or "First Majestic") (TSX:FR)(NYSE:AG)(FRANKFURT:FMV)(BVM:AG) is pleased to announce its 2016 Mineral Reserve and Resource estimates for its existing mineral property assets in Mexico as of December 31, 2016. Metal prices used to estimate the 2016 Reserve estimates were increased slightly compared to previous estimates to: $18.00/oz for silver, $1,250/oz for gold, $1.00/lb for lead and $1.15/lb for zinc.

"We began 2016 with a small exploration budget of only $9.9 million designed to primarily assist with our mining activities," stated Keith Neumeyer, President and CEO. "In the second half of 2016, we increased the exploration budget by 71% and returned our focus on growing the ounces in the ground. For 2017, we are investing $27.0 million to complete over 183,000 metres of diamond drilling across our Mexican assets. This renewed investment is expected to add significant growth to our Reserves and Resources in the years ahead."

The following table shows the total tonnage mined from each of the Company's six producing properties during 2016, including total ounces of silver and silver equivalent ounces produced from each property and the tonnage mined from delineated Reserves and Resources at each property. A portion of the production from each mine came from material other than Reserves or Resources, as set out below under the heading "Material Not in Reserves".

(1)    Silver-equivalent ounces are estimated considering: metal price assumptions, metallurgical recovery for the corresponding mineral type/mineral process and the metal payable of the corresponding contract of each mine. Details as to the method of calculation can be found in the applicable tables within the remainder of this section.
(2)    Totals may not add up due to rounding.

The Company completed a total of 97,576 metres of diamond drilling at its six operating mines in 2016, representing a 170% increase in metres drilled compared to the prior year.

For 2017, First Majestic is planning to invest $27.0 million towards exploration to drill approximately 183,000 metres at its core Mexican assets consisting of approximately 43,000 metres of diamond drilling intended to upgrade Resources to Reserves at La Parrilla, Del Toro, La Guitarra and Santa Elena; approximately 100,000 metres of diamond drilling intended to increase or add new Measured & Indicated or Inferred Resources at the six operating mines, with a focus at Nazareno in La Guitarra and the Ermitaño West project in Santa Elena; and drill approximately 40,000 metres at the Plomosas Silver Project. A combination of surface and underground drill rigs will focus on assisting mining activities, definition drilling and to support future updates to the Company's NI43-101 Technical Reports.

As of December 31, 2016, Proven and Probable Reserves totaled 116.7 million silver equivalent ounces, representing a 14% decrease or 18.6 million silver equivalent ounces in metal content compared to the prior estimate. This reduction is primarily due to the production depletion of 14.5 million silver equivalent ounces despite a modest increase of 3% in the assumed silver and gold prices and higher metal prices for lead and zinc. In addition, the reduction is the effect of an average increase of 10% in the cut-off grades for most of the mines. The escalation in the cut-off grade is a reflection of an increase of the mining and sustaining cost per tonne motivated by adopting more selective mining methods and the re-activation of sustaining development and near-mine exploration.

The Company's consolidated Measured and Indicated Resources totaled 139.6 million silver equivalent ounces, representing an 11% decrease from 2015 estimates primarily due to the production depletion and an increase of the production cost per tonne. In addition, Inferred Resources decreased 15% to 233.2 million silver equivalent ounces primarily due to the escalation in the cut-off grade as a reflection of an increase of the mining and sustaining cost per tonne.

The complete 2016 Mineral Reserve and Resource estimates for all metals, tonnage and grades are shown below in the following tables:

SPECIAL NOTE REGARDING FORWARD-LOOKING INFORMATION

This news release includes certain "Forward-Looking Statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995 and applicable Canadian securities laws. When used in this news release, the words "anticipate", "believe", "estimate", "expect", "target", "plan", "forecast", "may", "schedule" and similar words or expressions, identify forward-looking statements or information. These forward-looking statements or information relate to, among other things: the price of silver and other metals; the accuracy of mineral reserve and resource estimates and estimates of future production and costs of production at our properties; estimated production rates for silver and other payable metals produced by us, the estimated cost of development of our development projects; the effects of laws, regulations and government policies on our operations, including, without limitation, the laws in Mexico which currently have significant restrictions related to mining; obtaining or maintaining necessary permits, licences and approvals from government authorities; and continued access to necessary infrastructure, including, without limitation, access to power, land, water and roads to carry on activities as planned.

These statements reflect the Company's current views with respect to future events and are necessarily based upon a number of assumptions and estimates that, while considered reasonable by the Company, are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies. Many factors, both known and unknown, could cause actual results, performance or achievements to be materially different from the results, performance or achievements that are or may be expressed or implied by such forward-looking statements or information and the Company has made assumptions and estimates based on or related to many of these factors. Such factors include, without limitation: fluctuations in the spot and forward price of silver, gold, base metals or certain other commodities (such as natural gas, fuel oil and electricity); fluctuations in the currency markets (such as the Canadian dollar and Mexican peso versus the U.S. dollar); changes in national and local government, legislation, taxation, controls, regulations and political or economic developments in Canada, Mexico; operating or technical difficulties in connection with mining or development activities; risks and hazards associated with the business of mineral exploration, development and mining (including environmental hazards, industrial accidents, unusual or unexpected formations, pressures, cave-ins and flooding); risks relating to the credit worthiness or financial condition of suppliers, refiners and other parties with whom the Company does business; inability to obtain adequate insurance to cover risks and hazards; and the presence of laws and regulations that may impose restrictions on mining, including those currently enacted in Mexico; employee relations; relationships with and claims by local communities and indigenous populations; availability and increasing costs associated with mining inputs and labour; the speculative nature of mineral exploration and development, including the risks of obtaining necessary licenses, permits and approvals from government authorities; diminishing quantities or grades of mineral reserves as properties are mined; the Company's title to properties; and the factors identified under the caption "Risk Factors" in the Company's Annual Information Form, under the caption "Risks Relating to First Majestic's Business".

Investors are cautioned against attributing undue certainty to forward-looking statements or information. Although the Company has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be anticipated, estimated or intended. The Company does not intend, and does not assume any obligation, to update these forward-looking statements or information to reflect changes in assumptions or changes in circumstances or any other events affecting such statements or information, other than as required by applicable law.
