In the news release, Guyana Goldfields Inc. Reports Financial Results, Sets 2019 Production and Cost Guidance, issued 26-Mar-2019 by Guyana Goldfields Inc. over CNW, we are advised by the company that the 2019 Guidance section, 2nd sentence should read "152,500 ounces" rather than "152.5 million ounces" as originally issued inadvertently. The complete, corrected release follows:

TORONTO, March 26, 2019 - Guyana Goldfields Inc. (TSX: GUY) (the "Company") today disclosed financial results for the fourth quarter and full year 2018.

The Company also announced 2019 production and cost guidance for its wholly-owned Aurora Gold Mine ("Aurora") in Guyana. The guidance represents management's estimates following the development of a new mine plan by independent consultant Roscoe Postle Associates Inc., separately disclosed today.

A conference call is scheduled for tomorrow, Wednesday, March 27, 2019 at 10:00 am ET to discuss the results, as well as updated life of mine plan results. The Company previously released fourth quarter and full year 2018 operational results on January 14, 2019. All amounts are expressed in U.S. dollars unless otherwise stated.

Scott A. Caldwell, President & CEO, states, "The past year saw the Company deal with a number of challenges resulting from our lower than forecast planned mining rates and grades at Aurora. In response, the Company has acted on a number of fronts, starting with a refreshed Board of Directors, including the appointment of a new, non-executive Chairman, and a strengthened management team.

"With the right team, we developed a new strategy and began executing.  Among other things we eliminated an ineffective dual reporting structure, we refocused our mining exploration program and we restructured operations in Guyana. 

"We now have an accurate mine plan forecasting tool which will allow us to re-establish market expectations and meet our 2019 guidance. As we open a new chapter at Aurora, we will continue to focus on improving efficiency and maximizing operating cash flow, while maintaining our admirable safety record, including our achievement earlier this month of one million-person hours without a lost time injury."

Aurora Gold Mine Operational and Financial Summary Results

Fourth Quarter and Full Year 2018 Operational Results Summary

• Fourth quarter production of 42,750 ounces was the highest of 2018.
• On a full year basis, the Company produced 150,450 ounces, a decrease of 10,050 ounces compared to production from the prior year. The decrease was mainly attributable to a lower head grade of 1.99 g/t Au (2017 – 2.46 g/t Au), offset by higher mill throughputs averaging 7,100 tpd (2017 – 6,100 tpd).
• The daily average mining rate continued to increase through the fourth quarter, averaging 69,200 tpd, representing a new record and an increase of 176% when compared to the same quarter in 2017.  On a full year basis, the daily average mining rate improved by 50% in order to meet the increase in stripping ratio for Rory's Knoll open pit development.
• The mill processed 657,000 tonnes or 7,100 tpd in the fourth quarter. For the full year, the mill processed an average of 7,000 tpd, a 15% increase compared to an average of 6,100 tpd in the prior year. The increase can be mainly attributable to improved capital investment in the process plant and operating efficiencies. The Phase 2 mill expansion was commissioned in February 2019 and is expected to further improve recovery by up to 2%, throughput by 10%, and allow for 75% redundancy of the primary crusher.
• The mill head grade averaged 2.03 g/t Au for the quarter and 1.99 g/t Au for the year, a decrease from the prior year of 2.46 g/t Au. The decrease in head grade for the year was due to the unforeseen, late mobilization of the contractor (Stracon S.A) which resulted in a slow ramp up in the mining rate, limiting access to higher grade ore. This resulted in low grade stockpiles fed to the mill. In addition, the grade in the fourth quarter was lower than the model forecast, prompting management to engage a consultant to review the underlying resource model. 
• The increase in costs on a quarterly and full year basis were largely driven by increased mining and processing volumes, lower gold ounces sold from a lower average head grade and a higher strip ratio due to mine sequencing, and increased production costs.   

Selected Key Financial Statistics

Fourth Quarter and Full Year 2018 Financial Performance

• In the fourth quarter, a total of 37,450 ounces of gold were sold with an average realized gold price of $1,244 per ounce, resulting in revenues of $46.5 million, a decrease of $14.9 million compared to the fourth quarter of 2017. The decrease was due to fewer ounces of gold sold due to lower head grades, combined with a lower average realized gold price. On a full year basis, the Company generated revenues of $187.8 million from the sale of 148,350 ounces at an average realized price of $1,266 per ounce.
• Earnings from mine operations were $36.6 million for the year, a decline of $21.6 million from the prior year and largely driven by increased mining and processing volumes, lower gold ounces sold from lower average head grade and increased production costs. These declines in production costs were offset by lower deprecation and lower cost of sales adjustment.
• Net loss for the quarter amounted to $2.0 million ($0.01 earnings per diluted share) and earnings of $5.4 million ($0.03 earnings per diluted share) for the year.

Fourth Quarter and Full Year 2018 Liquidity and Capital Resources

• The Company finished the year with a cash balance of $82 million and total debt reduced to $40 million, down from $60 million as at the end of 2017. The Company elected not to make the voluntary accelerated debt repayment of $20 million during the fourth quarter of 2018, providing the Company with additional short-term liquidity.  Under the current terms of the loan agreement, the Company is scheduled to make eight additional quarterly payments of $5 million to retire the debt over the next two years.

2019 Guidance

The Company expects gold production to be between 145,000-160,000 ounces in 2019. The mid-point of production guidance is 152,500 ounces, which, if achieved, would represent an increase of 1.4% from 2018. The Company expects production will be evenly weighted in first and second half of the year.

The table below provides guidance for production and costs in 2019. As noted above, the 2019 guidance reflects an updated resource model and life of mine plan disclosed today.

The mining rate is expected to average 70,000 tpd through the year, with the primary ore sourced and development stripping at the Rory's Knoll pit. The development stripping will bring the average strip for the year to 10.9:1.

The mill is expected to run at an average of 7,000 tpd with recoveries expected to average 91.8%. Operating costs (including depreciation) and all-in sustaining costs are expected to be $1,175-$1,225. The higher costs are a result of the higher stripping during the year. Management will continue to actively pursue initiatives to lower costs. Some cost saving initiatives have already been executed in the early part of 2019 with the completion of the Phase 2 mill expansion and the reduction of the expatriate workforce.

The Board has approved an exploration program budget of $6.8 million covering additional surface brownfield drilling, initial underground drilling and the resumption of greenfield exploration for a combined total of approximately 30,000 metres.

Exploration Activities

During the third quarter of 2019, the Company shifted its exploration focus to more attractive near-mine targets.  Field programs were completed on Iroma, Wynamu and Arangoy.  Results of each project are being reviewed, and follow-up campaigns are being developed. 

Highlights from the 2018 program include:

• High grade assays returned from infill drilling at East Walcott, Mad Kiss, Aleck Hill and West Mad Kiss
• Underground targets generated within the Golden Square Mile for definition and resource category conversion drilling.
• Integrated data capture and management system fully implemented for Exploration and Mine Geology.
• Drilling expected to ramp up in 2019 with a focus on resource infill and evaluation of early-stage brownfield exploration targets. The 2019 budget of $6.75 million covers additional surface brownfield drilling, initial underground drilling and the resumption of greenfield exploration for a combined total of approximately 30,000 metres.

Two diamond drills were in operation in the fourth quarter and 34 holes totaling 5,527 metres were completed at an average rate of 42 metres per day on each rig. Drilling was conducted in Aleck Hill, North Aleck Hill, East Walcott, Mad Kiss, West Mad Kiss and Walcott Hill with the aim of defining high grade lodes and further understanding the structural controls on mineralization in Aurora.  Assay results can be found on the Company's press release filed February 11, 2019 entitled, "GUYANA GOLDFIELDS INC. REPORTS RESULTS FROM Q4/18 BROWNFIELD EXPLORATION DRILLING".

Underground Exploration Update

Mobilization and field work commenced in October 2018, with the portal collar scheduled to be completed in the fourth quarter.  The Company temporarily suspended work on the underground decline in November 2018 at the request of the Guyanese Environmental Protection Agency ("EPA"). Subsequently, the Company addressed all matters raised by the EPA and, in February 2019, received environmental authorization from the EPA to resume construction and development work on an underground exploration decline at Aurora. The underground decline is intended for exploration and definition drilling in support of eventual planned underground production.

Going forward, the contractor will complete and reinforce the collar and extend the decline 200 metres to fulfil the scope of the early works phase. The Company expects this work will take approximately three months to complete once the contractor is fully mobilized.  A budget of $2.0 million has been approved for the early works phase.

The Company is finalizing the review of bids received for the underground development contract with the target of final award in the second quarter of 2019.

The plan is to advance the exploration decline approximately 2,500 metres and provide a platform for further underground exploration and definition drilling. The decline is intended to provide access to all principal underground mining areas, including certain higher-grade zones in Mad Kiss and East Walcott that will allow the Company to further delineate exploration targets, potentially add mineral resources and help convert mineral resources to mineral reserves. In addition, the permit allows for test mining of up to 350,000 tonnes that could potentially provide supplemental mill feed during the development period and further unlock value at the Aurora Gold Mine. Management's intention is to develop an Underground Technology Centre, with a purpose of educating and transferring skills and technology required in all areas of underground technology.
