First Majestic Updates Mineral Reserve and Resource Estimates for Year End 2015 and Files Form 40-F Annual Report

VANCOUVER, BRITISH COLUMBIA--(Marketwired - March 31, 2016) - FIRST MAJESTIC SILVER CORP. (the "Company" or "First Majestic") (FRANKFURT:FMV)(TSX:FR)(NYSE:AG)(BVM:AG) is pleased to announce its 2015 Mineral Reserve and Resource estimates for its existing mineral property assets in Mexico as of December 31, 2015. Metal prices used to estimate the 2015 reserve estimates were reduced compared to previous estimates to: $17.50/oz for silver, $1,200/oz for gold, $0.85/lb for lead and $0.85/lb for zinc.

The following table shows the total tonnage mined from each of the Company's six producing properties during 2015, 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.

(1) Silver-equivalent grade is 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.
(2) Santa Elena production corresponds to the period October 1, 2015 to December 31, 2015.
(3) Totals may not add up due to rounding.

The Company completed 36,098 metres of diamond drilling at its six operating mines in 2015, representing an 18% reduction in metres drilled compared to the prior year. For 2016, First Majestic is planning to drill approximately 65,000 metres to further define known mineralized ore bodies at its operating mines. 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 NI 43-101 Technical Reports.

Metal content in the Proven and Probable Reserve category totaled 100.6 million ounces of silver, relatively unchanged from the Company's previous estimate of 101.1 million ounces of silver. The most significant change to Mineral Reserves, apart from the addition of the Santa Elena mine, occurred at La Encantada where the old tailings were upgraded from Inferred Resources to Probable Reserves following the significant improvement in silver recoveries from 15% to 70% due to the roasting of tailings. This upgrade resulted in a 48% decrease in the silver reserve grade to 143 g/t due to a 109% increase in tonnes, mostly consisting of low grade tailings. Silver metal content in the Measured and Indicated Resource category totaled 115.2 million ounces, representing a 24% decrease from 2014 estimates primarily due to the reclassification of the La Luz project as a historical resource, offset by the addition of the Santa Elena mine. In addition, the silver metal content in the Inferred Resource totaled 184.9 million ounces, representing an increase of 9% compared to previous estimates primarily due to the addition of the La Joya property which was acquired as a result of the acquisition of SilverCrest Mines Ltd.

The complete 2015 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.
