Filo Mining Reports Q1 2021 Results; Extends The Field Season and Prepares for Year-Round Exploration

VANCOUVER, May 6, 2021 - Filo Mining Corp. (TSXV: FIL) (Nasdaq First North Growth Market: FIL) (OTCQX: FLMMF) ("Filo Mining" or the "Company") is pleased to announce its results for the three months ended March 31, 2021. View PDF version

HIGHLIGHTS AND OUTLOOK

2020/2021 Campaign Exceeds 8,000 Drill Metre Target, Yields Exciting Initial Results, and Supports Increased Exploration Plans

Jamie Beck, President & CEO, commented, "It has been a really successful field program at Filo del Sol this year and with our strong treasury position we have elected to extend our drilling through the end of May 2021. As a result of this two-month extension, the Company now anticipates completing almost 12,000 metres of drilling - a 50% increase over the original plan. We are also undertaking efforts to prepare our camp to allow for year-round exploration activities, reducing the seasonality of our work programs and exploration news flow. Our initial findings have significantly expanded the Filo del Sol system, confirming the broader underlying system extends well beyond the deposit as currently defined. Clearly, we are encouraged by the early season results and look forward to reporting on additional assays once received."

The main focus of the Company during the first quarter of 2021 was the safe and effective execution of a diamond drill program at its flagship Filo del Sol Project. The program was designed to:

• Explore the 1.7 km gap between hole FSDH032 and a mineralized intersection in hole VRC093;
• Clarify the geological controls of significant zones of high-grade copper, gold and silver mineralization present within the overall mineralized envelope; and
• Allow for a portion of the sulphide mineralization to be added to Filo del Sol's Mineral Resource estimate by tightening the drill spacing within this deeper mineralization.

As of March 31, 2021, the Company has successfully completed approximately 8,500 metres of core drilling for the campaign, which exceeds the goal set at the outset. More importantly, the Company's initial assay results from the current program have been positive and put the Company in a strong position to exceed its operating objectives for the season.

The Initial assay results consist of complete assays on four completed holes, and partial results for another two holes (see News Releases dated March 31, 2021 and April 12, 2021 for details). Key highlights of the initial results reported to date include:

• Step-out holes FSDH043 and FSDH044 extend the known mineralization 1 kilometre to the north and 200 metres to the east, respectively. Both holes intersected grades which increased with depth and both ended in mineralization;
• FSDH040 provided infill of the large gap between the long, high-grade intersections from last season's program. Although FSDH040 was lost prior to reaching its target depth, it returned 117.5m of 0.69% CuEq (0.45% Cu; 0.29g/t Au, 2.4g/t Ag) starting from 94.0m, including a high-grade, supergene enriched zone of 26.0m of 1.37% CuEq (1.15% Cu; 0.28g/t Au; 2.3g/t Ag);
• Holes FSDH037 and FSDH041 extended the deposit's high-grade silver zone by 600 metres, and increased the total length of the silver zone to over 2 kilometres. Full assay results for both these holes are pending; and
• Hole FSDH042 discovered a new oxide gold zone 1.5 kilometres north of the main deposit, which confirms the vast exploration potential that still exists at Filo del Sol and that the larger system extends beyond the boundaries of the known deposit. This hole is highlighted by 48m at 1.01 g/t gold.

FINANCIAL RESULTS

SELECTED FINANCIAL INFORMATION

The Company incurred a net loss of $10.4 million during the three months ended March 31, 2021, comprised primarily of $12.5 million in exploration and project investigation costs and $0.7 million in G&A costs, which were partially offset by a gain of approximately $2.6 million resulting from the use of marketable securities for the purposes of facilitating intragroup funding transfers (the "Funding Gains"). For the 2020 comparative period, the Company reported a net loss of $11.8 million, consisting mainly of $11.9 million in exploration and project investigation costs and $0.9 million in G&A costs, which were partially offset by a Funding Gain of $0.7 million.

LIQUIDITY AND CAPITAL RESOURCES

As at March 31, 2021, the Company had cash of $28.9 million and net working capital of $23.1 million, compared to cash of $36.3 million and net working capital of $33.0 million as at December 31, 2020. The decrease in the Company's cash and net working capital is due primarily to funds used to advance exploration at the Filo del Sol Project, and to a lesser extent, funds spent for general corporate purposes. These decreases have been partially offset by $0.3 million in gross proceeds received by the Company in relation to the exercise of stock options for the three months ended March 31, 2021.

Moving forward, the Company expects that the majority of its treasury will be used to fund ongoing work programs to advance the Filo del Sol Project.
