2017 FIRST QUARTER HIGHLIGHTS

--  At Juanicipio, as a result of the significant mineralized discoveries
    beneath the Bonanza zone, Fresnillo plc and the Company have been
    considering alternate mine plans and other project enhancements to
    maximize the value of both the Bonanza Zone and the new Deep Zone.
    Considerations include increasing the processing plant nameplate
    capacity from 2,650 tonnes per day to 4,000 tonnes per day and sinking
    an internal shaft (or winze) to access the deeper zone sooner.

--  Fresnillo has indicated that permitting based on the upgraded design has
    already commenced, and that it expects its Board to give formal project
    development approval in the second quarter 2017.

--  A new resource estimate and the design upgrades are planned to be
    incorporated into a revised mine plan and a new MAG technical report,
    anticipated to be completed in the second quarter of 2017 and form the
    basis for MAG's formal project development approval.

--  The Juanicipio underground ramp decline reached the uppermost reaches of
    the Valdecanas Vein in December 2016 and intensified underground
    development has commenced to allow for the planned increase in
    processing capacity.

--  Assays from 13 additional exploration and infill drill holes were
    released in the quarter (see Press Release February 14, 2017), which
    along with the previously announced results (see Press Releases August
    15, 2016 and April 23, 2015) have:

    --  confirmed that continuous mineralization extends below the
        Valdecanas Bonanza Grade mineralization in both the East and West
        Veins;
    --  revealed a substantial widening of this deeper mineralization into a
        well-defined dilatant zone; and,
    --  resulted in the discovery of the new "Anticipada Vein", within the
        vein system.

--  A 20,000 metre 2017 exploration drill program for Minera Juanicipio was
    initiated subsequent to the quarter end, and will test various targets
    within the Joint Venture boundaries.

--  The Company remains well funded, with cash, cash equivalents, and term
    deposits totaling $132,442 as at March 31, 2017.

George Paspalas, President and CEO, commented, "as we head towards a Production Decision for Juanicipio, and embark on a more expanded exploration program this year, Minera Juanicipio remains focused on bringing the Bonanza Zone into operation as early as possible to maximize the return to shareholders."

FINANCIAL RESULTS - THREE MONTHS ENDED MARCH 31, 2017

As at March 31, 2017, the Company had working capital of $133,638 (March 31, 2016: $143,496) including cash, cash equivalents and term deposits of $132,442 (March 31, 2016: $142,028). The Company currently has no debt and has sufficient working capital to maintain all of its properties and currently planned programs for a period in excess of the next year.

In the three months ended March 31, 2017, the Company funded advances to Minera Juanicipio, which combined with MAG's Juanicipio expenditures on its own account, totaled $4,378 (March 31, 2016: $3,034). The Company makes cash advances to Minera Juanicipio as 'cash called' by the operator Fresnillo, based on approved joint venture budgets. Subsequent to the quarter end, the Company advanced a further $6,160 to Minera Juanicipio, representing its 44% share of a $14,000 cash call to fund intensified underground development on the Juanicipio Property.

The Company's net loss for the three months ended March 31, 2017 decreased to $312 (March 31, 2016: $1,297) or $0.004/share (March 31, 2016: $0.02/share) primarily due to deferred tax recoveries resulting from a strengthening Mexican Peso relative to the US dollar. A deferred (non-cash) tax recovery of $589 (March 31, 2016: $63) was recognized in the quarter related to the reversal for the deferred tax liability that was set up at December 31, 2016 in relation to temporary differences between the book and tax base of its Mexican non-monetary assets. With the strengthening of the Mexican Peso against the US$ from 20.66 Pesos/US$ on December 31, 2016 to 18.71 on March 31, 2017, the previously recognized deferred tax liability was reversed in the period. Likewise, the Company recorded its 44% equity income pick-up from Minera Juanicipio amounting to $572 (March 31, 2016: $43 equity loss pick up) related to this same strengthening of the Mexican Peso and the associated deferred tax recovery. No equity incentives other than 2,916 DSUs (March 31, 2016: 3,254) granted to directors in lieu of cash retainer and meeting fees, were granted in the quarter ended March 31, 2017 (March 31, 2016: nil). The Company recorded $367 (March 31, 2016: $579) of share based payment expense (a non-cash item) relating to equity incentives (stock options, restricted share units, performance share units and deferred share units) vesting to employees and consultants in the period. In other income and expenses during the quarter ended March 31, 2017, the Company recorded interest income on its cash, cash equivalents and term deposits of $362 (March 31, 2016: $113).

At Cinco de Mayo, the Company continues to believe that the property has significant geological potential and continues to maintain the mineral concessions in good standing. Although the Company has previously recognized an impairment on the property and has no current plans to conduct any geological exploration programs, efforts to regain the surface access continue.
