TORONTO, ON — (Marketwired) — 08/10/17 — (Please note that all dollar amounts in this news release are expressed in U.S. dollars unless otherwise indicated. Refer to the Q2 2017 management's discussion and analysis ("MD&A") and financial statements for more information.)

Primero Mining Corp. ("Primero" or the "Company") (TSX: P)(NYSE: PPP) today reported operating and financial results for the second quarter ended June 30, 2017, and provided an update on recent operating and corporate activities.

Highlights:

• Q2 2017 Production: Total production of 35,965 gold equivalent ounces¹, comprised of 11,903 ounces of gold and 0.97 million ounces of silver from San Dimas, and 20,731 ounces of gold from Black Fox, 27% lower than the 49,499 gold equivalent ounces produced in Q2 2016. Consolidated Q2 2017 total cash costs² were $852 per gold equivalent ounce, with consolidated all-in sustaining costs³ ("AISC") of $1,262per gold ounce.
• San Dimas Phased Restart Underway: San Dimas produced 15,234 gold equivalent ounces (11,903 ounces of gold and 0.97 million ounces of silver) in Q2 2017. Production during the quarter was impacted by a strike related to the renegotiation of the Collective Bargaining Agreement ("CBA"), with operations resuming on April 22, 2017. A phased restart of San Dimas operations has been initiated with overall performance in line with the restart plan during the quarter but slowing in recent weeks with continued labour disruption.
• Black Fox Outperforms on Higher Than Expected Underground Grade: Black Fox produced 20,731 ounces of gold in Q2 2017, compared to 15,172 ounces in Q2 2016. Underground mining was primarily focused on production from the Deep Central Zone, with underground gold grades averaging 7.09 g/t and a daily average mining rate of 747 tonnes per day ("TPD") of high-grade ore. All-in sustaining costs of $827 per ounce in Q2 2017 were significantly lower than the $1,362 per ounce realized in Q2 2016. The mine generated positive cash flows during the second quarter of 2017, and remains on track to achieve 2017 production guidance of between 50,000 and 60,000 ounces of gold.
• Financial Results Impacted by Asset Impairments: The Company recognized a net loss of $300.4 million in Q2 2017 compared to a net loss of $19.4 million in Q2 2016. The net loss incurred in Q2 2017 includes a $285.0 million impairment of the Company's assets. Adjusted net loss⁴was $2.9 million ($0.02 per share) for Q2 2017, compared to adjusted net loss of $3.5 million ($0.02 per share) for Q2 2016. Primero generated operating cash flow before working capital changes during Q2 2017 of $8.4 million ($0.04 per share).
• Strategic Review Update: Primero announced today that it has entered into an agreement to sell its Black Fox mine and complex in Timmins, Ontario for $35 million. The Company also continues to explore all alternatives to maximize stakeholder value related to its San Dimas mine in Mexico, including potential strategic investments, joint ventures, revision of the San Dimas Silver Purchase Agreement ("SPA") and a potential divestiture. At this time, there can be no certainty that these discussions will result in a resolution acceptable to all stakeholders.

"Although we saw an improvement in operations at Black Fox during the second quarter of 2017, the strike action at San Dimas early in the quarter followed by further labour disruptions have weighed on the Company," said Joseph F. Conway, Interim President and Chief Executive Officer. "I am pleased that we will reduce our total outstanding debt with the sale of the Black Fox mine. However, we still have outstanding debt that matures in November 2017, that will require additional funding or refinancing to repay in full. We have made progress with the Mexican tax authority and have started receiving VAT refund instalments, which has helped to improve our financial position."

Second Quarter 2017 Operating and Financial Results

Primero produced a total of 35,965 gold equivalent ounces in Q2 2017, which compares to 49,499 gold equivalent ounces produced in Q2 2016. Gold and silver production was 32,634 ounces and 0.97 million ounces respectively in Q2 2017. The Company incurred total cash costs per gold equivalent ounce of $852 during the quarter with AISC of $1,262 per gold ounce.

San Dimas produced 15,234 gold equivalent ounces (11,903 ounces of gold and 0.97 million ounces of silver) during the second quarter of 2017, compared to 34,327 gold equivalent ounces produced in Q2 2016. Production during the quarter was impacted by a strike action taken by unionized employees in February 2017. Agreement on the new CBA was achieved on April 17, 2017. The phased restart of the San Dimas operations commenced on April 22, 2017 with overall performance in line with the restart plan which was developed during the strike.

San Dimas mill throughput was affected by a 13-day suspension of milling activities in mid-June following the failure an anchor block affixed to one of eight cables supporting the tailings pipeline suspension bridge. Mill production was halted in order to reduce the environmental risk and to safely rebuild the anchor and re-tension the cable. The San Dimas mining operations continued uninterrupted during the tailings suspension bridge repair, and all ore produced was stockpiled at the mill site during this period. Full plant operations resumed on June 24, 2017, and the cost to repair the anchor block was minimal. The ore stockpile was fully processed by the mill in July.

Total cash costs on a gold-equivalent and by-product basis in the second quarter of 2017 were $1,144 and $1,115 per ounce, respectively, compared with $843 and $765 per ounce, respectively, in the second quarter of 2016. The increased unit costs were a result of the lower production rates in the current quarter and higher operating costs incurred during the initial restart of the San Dimas operations. All-in sustaining costs per gold ounce were $1,650 per ounce in the second quarter of 2017, compared to $1,063 per ounce in the second quarter of 2016. Sustaining capital expenditures were focused on underground development ($3.8 million) and drilling ($1.3 million). Subsequent to quarter-end, the Company reached an agreement with the union on the annual bonus payout relating to 2016. This resulted in an additional charge of $2.0 million incurred in the second quarter as annual bonus accrual, affecting total cash costs and all-in sustaining costs.

The Black Fox mine produced 20,731 ounces of gold in the second quarter of 2017 compared to 15,172 ounces in the second quarter of 2016. Underground mining in Q2 2107 was primarily focused on production from the Deep Central Zone, with underground gold grades averaging 7.09 g/t, a 59% increase from second quarter of 2016. The Black Fox underground mine averaged 747 TPD of high-grade ore production in Q2 2017.

Mill throughput averaged 2,396 TPD in the second quarter of 2017, compared to 2,524 TPD in the second quarter of 2016. Improved grade and tonnes from the underground mine drove an increase in the average mill head grade to 3.04 g/t compared to 2.14 g/t in the first quarter of 2016. This resulted in higher quarterly gold production despite the lower average milling rate.

Total cash cost per gold ounce were $637 in the second quarter of 2017, 27% lower than the $870 per ounce achieved in the second quarter of 2016. Total operating costs were similar in the second quarter of 2017 compared to the same period in 2016, however the increase in Q2 2017 gold production led to decreased total cash costs per gold ounce. All-in sustaining costs of $827 per ounce in Q2 2017 were significantly lower than the $1,362 per ounce in the second quarter of 2016 due to reduced capital expenditures and higher gold production. Capital expenditures were lower in Q2 2017 mainly due to lower underground development rates and other sustaining capital costs. Significant development costs were incurred in the second quarter of 2016 as Black Fox worked to complete the access ramp to the Deep Central Zone.

The Black Fox mine generated positive cash flows during the second quarter of 2017, as the mine achieved improved grades and a reduced cost structure which drove more profitable operations. The mine remains on track to achieve 2017 production guidance of between 50,000 and 60,000 ounces of gold at total cash costs of between $850 and $950 per ounce with all-in sustaining costs of between $1,150 and $1,250 per ounce.

Primero generated $16.2 million of revenue in Q2 2017, 62% lower than in Q2 2016 as a result selling 54% less gold equivalent ounces from San Dimas, noting that Black Fox has been classified as discontinued operations under IFRS (as a result of it being classified as held for sale). In Q2 2017, the Company sold 9,997 ounces of gold from San Dimas at an average realized price of $1,262 per ounce and 0.85 million ounces of silver at an average realized price of $4.28 per ounce. Revenue in Q2 2016 totalled $42.6 million from selling 28,873 ounces of gold from San Dimas at an average realized price of $1,265 per ounce, and 1.43 million ounces of silver at an average realized price of $4.24 per ounce.

All silver sold was delivered to Wheaton Precious Metals International Ltd. ("WPMI") under the silver purchase agreement⁵. The threshold above which the Company may sell 50% of silver produced for its own account at market rates under the silver purchase agreement for the 2016 contract year (August 6 of a year to August 5 of the following year) is 6.0 million ounces of silver. As of June 30, 2017, the Company has delivered 3.76 million ounces of silver towards this annual threshold. Gold produced at Black Fox is subject to a gold purchase agreement⁶ and as a result 1,472 ounces were sold to Sandstorm Gold Ltd. ("Sandstorm") at a fixed price of $531 per ounce in Q2 2017.

The Company recognized a net loss of $300.4 million in Q2 2017 compared to a net loss of $19.4 million in Q2 2016. The net loss incurred in Q2 2017 includes a $285.0 million impairment of the Company's assets. Adjusted net loss was $2.9 million ($0.02 per share) for Q2 2017, compared to adjusted net loss of $3.5 million ($0.02 per share) for Q2 2016. Adjusted net loss primarily excludes the asset impairments, net tax impact of foreign exchange rate changes on deferred tax balances, and the mark-to-market gain/loss on the convertible debenture and warrants.

As part of the strategic review process and the continued decline in its share price, the Company revalued its assets using assumptions derived from observable market indicators and the current life-of-mines plans for each operation. As a result, an impairment of $285.0 million has been recognized comprised of $195.0 million at the San Dimas mine, $40.0 million at the Black Fox Complex and $50.0 million at Cerro del Gallo project.

Primero generated operating cash flow before working capital changes during Q2 2017 of $8.4 million ($0.04 per share). This compares to operating cash flow of $11.2 million ($0.07 per share) in Q2 2016.

Liquidity Update

The Company's total liquidity position at June 30, 2017 totalled $22.1 million, comprised of $12.1 million in cash and $10.0 million available under its existing revolving credit facility ("RCF"). As previously disclosed, Primero extended the maturity of its RCF to November 23, 2017. Primero's current cash position is similar to its quarter end and the Company has fully-drawn its $75 million RCF.

As at June 30, 2017 there are $33.5 million in VAT and $22.8 million income taxes receivable outstanding. The Company has filed its VAT and income tax refunds in compliance with the Mexican law and is working co-operatively and more closely with the SAT. Subsequent to the quarter end, in July 2017 the Company received $2.4 million in VAT refunds. The Company is working with the SAT to arrange for the remaining eligible outstanding amounts to be refunded in due course.

Primero highlights the significant liquidity risk imposed by the pending RCF maturity date of November 23, 2017, and notes that it may not be able to fully repay its debt obligations under the RCF without obtaining an extension of the existing RCF or an additional source of debt or equity financing. The Company will continue to explore all operational and financial alternatives available.

San Dimas Operations Update

Despite seeing initial improvements in relations with unionized workers following the resolution of the San Dimas strike in Q2 2017, the situation degraded in July 2017 with the negotiation of the 2016 annual workers' bonus ("PTU Bonus"). The site experienced a significant work slowdown in July, which included coercive tactics employed by unionized workers to pressure the Company to agree with their demands, such as a forced shutdown of longhole drill rigs, terminating shifts early by walking off the jobsite, refusing to work as scheduled, and other general production slowdowns.

The PTU Bonus negotiation was resolved on July 29, 2017 with an agreement on the amount of the annual bonus and an immediate payment of two thirds of the agreed bonus. In order to motivate the workers to return to productive work practices, the second payment of one third of the total agreed amount, will be delivered in December 2017, provided there is adherence to the CBA. Despite this, and based on union relations over the last 18 months, the Company believes that labour disruptions may continue to adversely affect the Company's ability to profitably operate the San Dimas mine.

At this time, Primero is not adjusting its San Dimas 2017 production guidance of 90,000 to 110,000 gold equivalent ounces at total cash costs of $650 to $800 per gold equivalent ounce, since the mine currently remains on-plan. However, the Company notes that the phased restart plan requires a step increase in production levels through the remainder of the year. Primero believes that production will track toward the lower end of the guidance range and there is the risk of a guidance reduction in 2017 if productivity does not increase as planned and union relations do not improve.

Despite significant investment at San Dimas, the Company's exploration efforts have not identified large replacement veins for the depleting Roberta and Robertita veins. Without new large veins coming into production or changes to the operating environment, mining rates above 1,800 tonnes per day ("TPD") may not be possible.

In light of current site conditions and the Company's near-term focus on maintaining liquidity and cash conservation, the San Dimas capital plan for 2017 has been re-evaluated and scaled back by $17.7 million to $33.4 million, retaining only capital expenditures necessary to maintain current operating levels. This has resulted in a reduction in the exploration and underground development spending associated with exploration planned for 2017, and as such has resulted in a decrease in expected all-in sustaining costs. All-in sustaining costs are now expected to be between $900 and $1,050 per ounce in 2017 from $1,100 to $1,300 per ounce previously. The reduction in 2017 planned exploration and development spending may affect the Company's ability to achieve expected production levels in future years.

Strategic Review Update

As previously announced, the Company's Board of Directors initiated a strategic review process to explore alternatives to improve shareholder value. Today the Company announced that it has entered into an agreement with McEwen Mining Inc. (NYSE: MUX)(TSX: MUX) ("McEwen") to sell its interest in the Black Fox mine and associated assets located near Timmins, Ontario, Canada (the "Transaction"). Under the terms of the agreement, Primero will receive consideration of $35 million, in cash, subject to certain closing adjustments. Definitive documentation is expected to be completed before the end of this month and the transaction remains subject to customary conditions of closing.

In addition, the Company will continue to explore ways to improve stakeholder value related to its San Dimas mine in Mexico, including potential strategic investments, joint ventures, revision of the Company's streaming agreement and potential divestiture.

Primero has received a number of proposals from interested parties regarding a potential acquisition of the San Dimas operation. However, all proposals received require a significant revision of the SPA with Wheaton Precious Metals ("WPM"). As a result discussions are currently focused on potential changes to the SPA with WPM and distribution of proceeds among stakeholders. At this time, there can be no certainty that these discussions will result in a resolution acceptable to all stakeholders.

The Company has identified that at lower production rates the obligations under the current SPA do not allow for a sustainable operation at San Dimas. The Company has been in discussions WPM about a sustainable solution for all parties but there can be no assurance that an acceptable solution will be achieved. Without a revision to the SPA the San Dimas mine life will become significantly shorter as a result of the Company's inability to invest in exploration and development due to the economics inherent in the SPA and the current operating environment in Mexico and at San Dimas itself.

Primero will continue to advance discussions with financiers to extend or refinance the $75 million RCF due in November 2017 and will look to reduce total debt through potential asset sales, joint ventures and strategic investments. Other potential sources of funds include cash flows from operations, VAT and income tax refunds, and additional debt or equity financings.

This release should be read in conjunction with Primero's second quarter 2017 financial statements and MD&A report on the Company's website, www.primeromining.com, in the "Financial Reports" section under "Investors", or on the SEDAR website at www.sedar.com, or on the Edgar website www.sec.gov.

⁽¹⁾ "Gold equivalent ounces" include silver ounces produced, and converted to a gold equivalent based on a ratio of the average commodity prices realized for each period. The ratio for the second quarter 2017 for San Dimas was based on realized prices of $1,262 per ounce of gold and $4.28 per ounce of silver.

⁽²⁾ Total cash costs per gold equivalent ounce and total cash costs on a by-product basis are non-GAAP measures. Total cash costs per gold equivalent ounce are defined as cost of production (including refining costs) divided by the total number of gold equivalent ounces produced. Total cash costs on a by-product basis are calculated by deducting the by-product silver credits from operating costs. The Company reports total cash costs on a production basis. In the gold mining industry, these are common performance measures but do not have any standardized meaning, and are non-GAAP measures. The Company follows the recommendations of the Gold Institute standard. The Company believes that, in addition to conventional measures, prepared in accordance with GAAP, certain investors use this information to evaluate the Company's performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. See the second quarter 2017 MD&A for a reconciliation of total cash costs to reported operating expenses (the nearest GAAP measure).

⁽³⁾ The Company, in conjunction with an initiative undertaken within the gold mining industry, has adopted an all-in sustaining cost non-GAAP performance measure that the Company believes more fully defines the total cost associated with producing gold; however, this performance measure has no standardized meaning. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The Company reports this measure on a gold ounces produced basis. For the purposes of calculating all-in sustaining costs at individual mine sites, the Company does not include corporate general and administrative expenses. Corporate general and administrative expenses are included in the computation of all-in sustaining costs per consolidated gold ounce. Refer to the Company's second quarter 2017 MD&A for a reconciliation of all-in sustaining costs per gold ounce.

⁽⁴⁾ Adjusted net income (loss) and adjusted net income (loss) per share are non-GAAP measures. Neither of these non-GAAP performance measures has any standardized meaning and is therefore unlikely to be comparable to other measures presented by other issuers. The Company believes that, in addition to conventional measures prepared in accordance with GAAP, the Company and certain investors use this information to evaluate the Company's performance. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Refer to the second quarter 2017 MD&A for a reconciliation of adjusted net income (loss) to reported net income (loss).

⁽⁵⁾ According to the silver purchase agreement between the Company and WPM, until August 6, 2015 Primero delivered to WPM a per annum amount equal to the first 3.5 million ounces of silver produced at San Dimas and 50% of any excess at $4.12 per ounce (increasing by 1% per year). Thereafter Primero will deliver to WPM a per annum amount equal to the first 6.0 million ounces of silver produced at San Dimas and 50% of any excess at $4.20 per ounce (increasing by 1% per year). The Company will receive silver spot prices only after the annual threshold amount has been delivered.

⁽⁶⁾ Black Fox was subject to a gold purchase agreement which continues and was assumed by the Company upon its acquisition of the mine. According to the gold purchase agreement, Sandstorm is entitled to 8% of production at the Black Fox mine and 6.3% at the Pike River property.
