Business Overview

In 2019, we were faced with many challenges, both from an operational and management perspective. The significant and ongoing reviews of mine plans during the year negatively impacted our ability to practically implement a plan at the mine, leading to lower than anticipated productivity performance, the mining of satellite ore bodies with mixed success, and the processing of ore from low grade stockpiles.

We continued to review a significant number of mine plans and scenarios during the first quarter of 2020 to find a mine sequence with continuous ore release while safely progressing waste stripping of the next phase of open pit mining, but concluded that these objectives were not achievable in tandem. The life of mine plan developed by Roscoe Postle Associates Inc., as disclosed in the Technical Report dated March 31, 2020 (the "New LOM Plan") incorporated the results of our comprehensive review and reflected a four to six month ore gap which would commence in the second quarter of 2020. The New LOM Plan, if implemented as contemplated, requires approximately $100 million in funding for the next phase of mine development, excluding potential impacts of the Covid-19 worldwide pandemic or delays in financing. Management evaluated a number of potential financing alternatives to address the funding gap and commenced a concurrent review of strategic alternatives in the first quarter of 2020.

Transaction Update and Upcoming Shareholder Meeting

As announced on April 27, 2020, the Company has entered into a definitive arrangement agreement (the "Arrangement Agreement") with Silvercorp whereby Silvercorp will acquire all of the issued and outstanding common shares of the Company not already owned by Silvercorp pursuant to a court-approved plan of arrangement under the Canada Business Corporations Act (the "Arrangement"). Concurrently with entering into the Arrangement Agreement, Silvercorp and the Company also entered into an agreement for a bridge loan facility (the "Bridge Loan Facility"), whereby Silvercorp will lend the Company up to $15 million for use by the Company related to ongoing operations at the Aurora Mine, as well as for certain working capital and general corporate purposes.

The closing of the Arrangement is subject to satisfaction of certain conditions, including the approval of 66?% of votes cast by shareholders of the Company, obtaining court and regulatory approvals and other customary conditions for a transaction of this nature to be satisfied or waived.

We have scheduled an annual and special meeting for June 29, 2020 (the "Meeting"), at which time shareholders will be asked to vote on the Arrangement. Subject to the receipt of shareholder approval and all other necessary approvals and the satisfaction of all other closing conditions, the Arrangement is expected to close in early July 2020. A copy of the Arrangement Agreement and related documents are available on the Company's SEDAR profile at www.sedar.com.

Outlook for 2020

On March 18, 2020, as a result of COVID-19 related travel restrictions in and out of Guyana, we announced the temporary suspension of underground development. Total development meters reached 1,156 meters prior to work being suspended.

In addition, given the current travel restrictions, and the funding gap for the next phase of the New LOM Plan, the next phase of mine development will not proceed until these restrictions are lifted. This will result in a period of care and maintenance at site once Rory's Knoll Phase 4 is completed and satellite ore and low-grade stockpiles are depleted in the second quarter of 2020. Thereafter, a period of care and maintenance of more than a quarter will likely result in no further production from the open pit in 2020. Production, prior to care and maintenance, is estimated to total approximately 35,000 to 45,000 ounces in the first half of 2020. The site will continue to be maintained and environmental risks managed to ensure safety and security of the mine until operations can be resumed.

CEO Commentary

"Following a challenging 2019 we are pleased to be moving forward with implementing the arrangement transaction with Silvercorp. This transaction will allow the citizens and the Government of Guyana to continue to benefit from the Aurora Gold Mine and will facilitate the transition from open pit to underground mining" said Alan Pangbourne. "While we will be entering into a temporary period of care and maintenance once the current open pit mining ceases, we are pleased that Silvercorp, with its significant underground experience and strong balance sheet, will continue to advance the underground project at Aurora."

Mr. Pangbourne further commented; "This transaction is a good outcome for our shareholders and provides them with an immediate and significant upfront premium and exposure to a geographically diverse mid-tier precious metal company through the opportunity for ownership of shares of Silvercorp. We look forward to working with Silvercorp to close this transaction."
