Sherritt International Corporation ("Sherritt" or the "Corporation") (TSX:S.TO), the world leader in the mining and refining of nickel from lateritic ores, today reported its financial results for the three months ended March 31, 2016.

"Our focus remains steadfast on maintaining liquidity and enforcing strict cost discipline and smart capital allocation across our business," said David Pathe, President and CEO, Sherritt International. "Consistent with that focus, we continue to decline to fund Ambatovy under the current capital structure. Liquidity at the end of the quarter remained strong after credit facility debt repayment of $45 million."

Q1 HIGHLIGHTS (1)

• Nickel and oil prices made new multi-year lows in the quarter, although prices for both commodities rallied somewhat in April, with WTI crude trading in a volatile fashion. The nickel price rally has been more cautious, with recent US$4/lb nickel up roughly 15% from the low in Feburary. Strong cobalt and fertilizer production provided some support to mitigate the first quarter impact of the lower nickel production and lower nickel and oil average realized prices.

• Net direct cash costs of US$4.41/lb at Ambatovy and US$3.34/lb at the Moa JV remain well below the 50th percentile of C1 costs tracked by Wood Mackenzie, and on average are down 24% from the year ago quarter.

• Finished nickel production was down 4% from the year ago quarter, as Ambatovy's process plant experienced a number of unrelated reliability issues that increased downtime. Although this affected first quarter production by approximately 1,000 tonnes (100% basis), replacement components have been installed or other mitigation has occurred. Production guidance for Ambatovy remains at 48,000 - 50,000 tonnes finished nickel (100% basis).

• Cash, cash equivalents and short-term investments ended the first quarter at $370 million, after repaying and terminating the $35 million line of credit and making a $10 million repayment on the revolving term credit facility.

OUTLOOK AND SIGNIFICANT ITEMS

• Production guidance remains unchanged for all operations.

• Capital spending guidance has been reduced by US$9 million, attributable to lower spending in Oil & Gas as only one well will be drilled in Block 10 this year.

All amounts are Canadian dollars unless otherwise indicated.

During the first quarter, $(79.1) million $(0.27) per share in adjusting items occurred, primarily an unrealized foreign exchange gain of $76 million, as the Canadian dollar strengthened by approximately 10 cents from period end December 31, 2015 to period end March 31, 2016.

REVIEW OF OPERATIONS

METALS

METAL MARKETS

Although nickel prices continued their decline to lows not experienced in the past decade, Sherritt customer demand has been firm with demand from China climbing. Nickel sales into China increased over the prior year period at both the Moa JV and the Ambatovy JV, which is consistent with an overall increase reported in Chinese nickel imports. Importantly, the largest increase has been in non-LME deliverable metal, which indicates demand from end users rather than metal traders who tend to prefer LME-deliverable material. The increase experienced by Sherritt in Chinese demand is linked to declining availability of NPI and stainless steel scrap. Recent Chinese NPI production estimates for 2016 have pointed to approximately 300,000 tonnes compared to levels of approximately 350,000 - 375,000 tonnes in 2015.

Cobalt demand and pricing have been rising slowly, as cobalt supply suffers when nickel and copper production are cut back, and we are beginning to see evidence of supply cuts in these commodities. Cobalt is a smaller market, with most production occurring as by-products of copper or nickel production. Demand growth has come from battery manufacturers shifting from small consumer batteries (laptops, cell phones, etc.) to larger storage applications such as automotive, power tools and industrial/household storage. Sherritt's high grade cobalt remains well positioned to meet the demand for these applications as it is approved by the majority of major rechargeable battery manufacturers and recognized for its high purity.

Moa Joint Venture (50% interest) and Fort Site (100%)

Adjusted EBITDA of $(0.2) million in the quarter declined to levels that have not been seen since the first quarter of 2009, as nickel prices continued their downward trend.

Finished nickel production of 4,242 tonnes (50% basis) in the first quarter of 2016 was down marginally from the comparable quarter in 2015, although above planned levels. Mixed sulphide production was down 11%, which could have an impact on finished nickel production in the second quarter. Heavy rainfall in the first quarter limited access to planned mining faces, which impacted ore grade and was the primary cause for the lower production of mixed sulphides in the quarter. Refinery production remained relatively strong despite the limited mixed sulphide availability because of third party feed usage and a drawdown of mixed sulphides inventory.

Finished cobalt production of 499 tonnes (50% basis) in the first quarter was up 17% from last year's comparable quarter, reflecting stable plant operation.

The nickel recovery was 88% in the first quarter of 2016, consistent with the first quarter of last year.

The NDCC of US$3.34 per pound of nickel in the first quarter of 2016 was a significant improvement over last year's comparable quarter, and reflects mainly lower mining, processing and refining costs (driven by lower fuel oil, sulphuric acid and sulphur prices) and a higher fertilizer credit. In addition, the weaker Canadian dollar had a positive impact on refining costs, as the Fort Saskatchewan refinery costs are Canadian dollar denominated.

Continuing cost discipline is evident, as the first quarter 2016 NDCC is comparable to the fourth quarter 2015 NDCC of US$2.90 per pound when seasonal fertilizer sales are taken into account.

Capital spending of $7.8 million in the quarter is similar to its comparable quarter last year, with most of the capital spending this quarter related to the acid plant construction. The expansion capital of $4 million (US$3 million) refers to the 50% share of the acid plant, which has a total construction and commissioning budget of US$67 million (100% basis). On a 100% basis, counting the US$6 million spent in the first quarter of 2016 plus expenditures incurred in 2014 and 2015, approximately US$47 million has been spent on the acid plant. Acid plant construction progress is greater than 95% complete and pre-commissioning activities have been initiated with full operation expected in the third quarter of 2016.

Ambatovy Joint Venture (40% interest)

Adjusted EBITDA in the first quarter of 2016 was $(12.8) million compared to Adjusted EBITDA of $4.3 million in the same quarter last year. While lower nickel prices were the main factor affecting Ambatovy's results, the quarter's finished nickel production of 4,442 tonnes (40% basis) was also lower than expected. Ambatovy continued to improve in safety performance, and met expectations for ore grade and throughput rate, process control and stability, and product quality. However, the process plant experienced a number of unrelated reliability issues on equipment in the HPAL plant that resulted in lower nickel production. These issues are well understood, and Sherritt is addressing the challenge through both progressive replacement of problematic equipment and the implementation of a comprehensive asset management program. The impacts in the first quarter have not required any change to production or capital spending guidance, as they have been largely addressed during the quarter, with additional improvements to be implemented over the next one or two months.

First quarter finished cobalt production of 365 tonnes was also impacted by the unplanned downtime events, although cobalt revenue benefited from timing of sales as the average reference price of cobalt was approximately 6% higher in the fourth quarter of 2015.

Port operations at Ambatovy were interrupted for 21 days during the quarter while Sherritt confirmed Ambatovy's status regarding the Government of Madagascar's imposition of a new security-related protocol, the Advance Cargo Declaration, on all port users. This matter was resolved with no material financial impact and no impact to production.

Despite the lower first quarter production results, the trend in NDCC continues to be positive, as NDCC of US$4.41/lb is only 8% higher than the fourth quarter 2015 record low NDCC of US$4.07/lb, with finished nickel production down 9% in the same comparison period. First quarter 2016 NDCC was down 23% over its comparable quarter last year (NDCC of US$5.74/lb) on similar production levels.

Ambatovy Funding

As Sherritt announced in its fourth quarter and 2015 year end results disclosure, Ambatovy cash calls due in January this year amounted to US$50 million, with funding of US$30 million provided by partners Sumitomo Corp. and Korea Resources Corp. (KORES). Total cash funding provided by Sumitomo and KORES has increased to US$51 million, pursuant to additional cash calls of US$35 million. By agreement amongst the partners, Sherritt's unfunded amounts remain payable with accrued interest. These amounts will be subtracted from future Ambatovy Joint Venture distributions, or may be set off against other amounts owed to Sherritt. Sherritt also has the option to pay the amounts in cash at any time, at Sherritt's election. Until the funding deficit is addressed, and subject to continued discussions with the Ambatovy partners, Sherritt will not exercise its Ambatovy voting rights.

Sherritt continues not to fund further cash calls at this time due to the structure of the Ambatovy partner loans, which, at current nickel prices, effectively reduce Sherritt's 40% interest in Ambatovy to a 12% economic interest (1). Sherritt continues to serve as operator, as constructive discussions are ongoing between partners and senior lenders regarding future funding of Ambatovy and modifications to the principal amortization on the existing senior loan.

Adjusted EBITDA in the first quarter of $4.0 million remained positive, although reference prices declined further from the lows of the fourth quarter 2015. In the first quarter this year, WTI prices averaged US$33.40/barrel, down 21% from fourth quarter 2015 levels, and down 31% from their average in the first quarter last year. Gulf Fuel Oil 6, the relevant benchmark for Sherritt's Cuban oil production, experienced a larger decline, where prices fell 29% from fourth quarter 2015 levels and 52% from the first quarter 2015. In the first quarter this year, Gulf Fuel Oil 6 averaged only 63% of WTI, compared to 92% in the first quarter of 2015.

Unit operating costs are higher on the lower production base and a lower Canadian dollar, but are lower than fourth quarter 2015 unit operating costs, and will fluctuate during the year, with the amount of workover activity and changes in the exchange rate.

First quarter GWI oil production in Cuba was as expected, down from the same quarter last year, consistent with the natural reservoir declines in our existing Production Sharing Contract (PSC) wells. Net working-interest (NWI) oil production in Cuba of 9,890 bopd, however, is down only slightly from its levels in the first quarter and the fourth quarter last year. This trend follows the pattern established last year with falling oil prices, where cost recovery oil increased because of lower oil prices.

Quarterly free cash flow of $(2.4) million is an improvement over the year ago quarter, when capex was higher. Capital spending in the first quarter of $4.7 million related mainly to drilling rig maintenance, well workovers and equipment purchases. Drilling activity in 2016 will be focused on the preparation and drilling of Block 10, as previously announced. Drilling the first well has shifted to the second half of the year, and with this timing, only one well will be drilled in 2016 (compared to the two originally planned). This is the main reason for the current capital expenditures guidance being revised to US$34 million from previous guidance of US$43 million. Results of the first well are to be evaluated in the fourth quarter.

Block 10 is one of two new PSC's which Sherritt signed in 2014 with the Cuban agency, covering 261 square kilometres for a 25-year term. Sherritt originally held Block 10 in the Bay of Cardenas, and drilled one well in June 1994. The well was drilled using an offshore drilling rig, and was tested at 3,750 barrels of oil per day. Since then, significant advances in horizontal drilling technology have made drilling the prospect from an onshore location viable.

Quarterly Adjusted EBITDA of $8.7 million is up over its comparable quarter last year, mainly due to a higher average realized price from the weaker Canadian dollar. Production was higher than its year ago period, although down from quarterly production in fourth quarter 2015 due to slightly less gas being available for power generation.

The increase in operating costs on a year over year basis reflects mainly the weaker Canadian dollar; however, the first quarter of 2016 unit operating costs have reverted back to more normal ranges following the anomaly that existed in the fourth quarter of 2015 when a number of large maintenance activities occurred which had a disproportionate impact on the quarterly results.

Free cash flow generation of $0.8 million in the quarter is low compared to each of the four quarters last year. The power segment benefited in each of the four quarters of last year from principal repayments and interest payments received on the Energas conditional sales agreement ($71.6 million received for 2015). Due to higher capital spending and the current payment schedule, the repayment under the conditional sales agreement for 2016 is estimated at $34 million.

STRATEGIC PRIORITIES

The table below lists Sherritt's strategic priorities for 2016. The 2016 Strategic Priorities reflect the continuing depressed commodity outlook and the Corporation's responsibility to preserve liquidity, continue to drive down costs, and execute rational capital allocation plans. Sherritt's purpose, originally communicated in 2014, continues to be a low-cost nickel producer that creates sustainable prosperity for our employees, investors and communities.

OUTLOOK

2016 PRODUCTION AND CAPITAL SPENDING GUIDANCE

In 2016, Sherritt has made certain modifications to how guidance is presented. For example, capital spending estimates are presented in US dollars. In the quarterly reporting, actual capital spending is presented in Canadian dollars consistent with Sherritt's reporting currency, but estimates and forward looking information continue to be provided in US dollars. This change in presentation is intended to align with Sherritt's capital budgeting practices, and to mitigate the change to capital spending that arises from translation to the Canadian dollar reporting currency. In Sherritt's full year and Q4 2015 reporting, when guidance was first presented, the forecast exchange rate was Cdn$1.36 per U.S. dollar. Capital projects in the Metals business are generally US dollar expenditures, while in Oil & Gas, the expenditures are roughly 50% Canadian dollar denominated and 50% U.S. dollar denominated.

NON-GAAP MEASURES

The Corporation uses combined results, Adjusted EBITDA, average-realized price, unit operating cost, and adjusted operating cash flow to monitor the performance of the Corporation and its operating divisions and believes these measures enable investors and analysts to compare the Corporation's financial performance with its competitors and evaluate the results of its underlying business. These measures do not have a standard definition under IFRS and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. As these measures do not have a standardized meaning, they may not be comparable to similar measures provided by other companies. See Sherritt's Management's Discussion and Analysis for the period ended March 31, 2016 for further information.

CONFERENCE CALL AND WEBCAST

Sherritt will hold its quarterly conference call and webcast tomorrow at 10:00 a.m. Eastern Time.
