ORLA MINING FILES UPDATED TECHNICAL REPORT ON CERRO QUEMA TO INCLUDE CABALLITO MINERAL RESOURCE

VANCOUVER, BC, Jan. 20, 2022 /CNW/ - Orla Mining Ltd. (TSX: OLA) (NYSE: ORLA) ("Orla" or the "Company") is pleased to announce that the Company has filed an updated technical report, prepared in accordance with the disclosure standards under National Instrument 43-101 ("NI 43-101") for its Cerro Quema project ("Cerro Quema") located in the Azuero Peninsula, Los Santos Province, Panama. The updated technical report now includes the independent mineral resource estimate for the Caballito copper-gold deposit, details of which were previously announced (see News Release dated December 6, 2021).

"We remain excited about the diversity of our growth options in Panama and are progressing on all fronts", said Jason Simpson, President and Chief Executive Officer of Orla Mining. "This includes the promising copper development opportunity, the robust oxide heap leach project, and a prospective exploration package."

The following tables present the mineral resource estimation for the Cerro Quema oxide project as well as the separate and additional Caballito deposit. The mineral resource on the Cerro Quema oxide project has been updated from the previously filed technical report dated September 7, 2021. In the previously filed technical report, the mixed category under the indicated and inferred resource for the Cerro Quema oxide project was misstated and has been corrected in the updated technical report. This correction does not have an impact on the previously disclosed mineral reserve estimate or the results of the pre-feasibility study on the Cerro Quema oxide project.

Mineral Resources Notes:

1.	The qualified person responsible for the Mineral Resource is Sue Bird, P. Eng of Moose Mountain Technical Services.  Sue Bird is independent of Orla Mining Ltd.
2.	Resources are reported using the 2014 CIM Definition Standards and were estimated using the 2019 CIM Best Practices Guidelines.
3.	Mineral Resources are reported inclusive of Mineral Reserves.
4.	Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
5.	The Mineral Resource is based on the following assumptions: for Pava and Quemita: Metal prices of US$1,600/oz gold price and US$18/oz silver price. 125% price case pit; 99.9% payable Au; 98.0% payable Ag; $1.40/oz Au and $1.20/oz Ag offsite costs (refining, transport and insurance); At Caballito: 100% price pit with metal prices of US$1,600/oz gold price, US$3.50/lb copper price and US$20/oz silver price and the following smelter terms: In the Oxides: 99% payable Au; 98.0% payable Ag; In the Sulphide 90% payable Au and Ag, and 96% payable Cu; Offsite costs of US$1.40/oz Au and US$1.20/oz Ag in the oxides and offsite costs (refining, transport and insurance) of US$16.30/WMT for Au, US$116.50/WMT for Cu and US$3.20/WMT for Ag in the sulphides; for all deposits a 4% net smelter returns ("NSR") royalty for Au and Ag and a 5% NSR royalty for Cu.
6.	Metallurgical recoveries are for Pava:  88% Au in oxides and mixed, for Quema:  86% Au in oxides and mixed for Pava, Ag recovery is 30% oxides and mixed in Pava, Ag recovery is 15% in oxides and mixed in Quema. The metallurgical recovery at Caballito have been estimated as 90% for Cu, 55% for Au, and 45% for Ag in the sulphides, and 88% for Au, 45% for Ag and 0% for Cu in the oxides.
7.	The Mineral Resource has been confined by a "reasonable prospects of eventual economic extraction" pit using the following cost assumptions: At Quemita: a mining cost of US$2.56 At La Pava a mining cost of $US2.40 at Caballito a mining cost of US$2.20/tonne for both materials to be processed and waste.  Processing + G&A costs for each deposit and metallurgical zone are the base case cutoff NSR values.
8.	The base case cut-off is an NSR of: for Pava, US$6.34/tonne for oxide and US$9.18/tonne for mixed; for Quema, US$6.50 for oxides and US$8.35 for mixed; and for Cabllito, US$6.34/tonne for oxide and US$15.00/tonne for sulphide.
9.	Pit slope angles are 40º.
10.	The bulk density in La Pava and Quemita has been determined by Alteration Zone and Core recovery and ranges between 2.07 and 2.62. The bulk density at Caballito has been assigned values of 2.34 and 2.70 tonnes/m3 in the oxides and sulphides, respectively based on bulk density measurements.
11.	Numbers may not add due to rounding.

Cautionary Note to U.S. Readers

The disclosure contained or referenced herein uses mineral reserve and mineral resource classification terms that comply with reporting standards in Canada, and mineral reserve and mineral resource estimates are made in accordance with Canadian NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum — CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the "CIM Definition Standards"). Canadian NI 43-101 establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects.  These standards differ significantly from the mineral reserve disclosure requirements of the United States Securities Exchange Commission (the "SEC") set forth in Industry Guide 7. Consequently, information regarding mineralization contained or referenced herein is not comparable to similar information that would generally be disclosed by U.S. companies under Industry Guide 7 in accordance with the rules of the SEC which applied to U.S. filings prior to the current SEC Modernization Rules (as defined herein). Further, the SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the Securities Exchange Act of 1934 ("Exchange Act"). These amendments became effective February 25, 2019 (the "SEC Modernization Rules") and, commencing for registrants with their first fiscal year beginning on or after January 1, 2021, the SEC Modernization Rules replace the historical property disclosure requirements included in SEC Industry Guide 7.  As a foreign private issuer that files its annual report on Form 40-F with the SEC pursuant to the multi-jurisdictional disclosure system, the Company is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101 and the CIM Definition Standards. The SEC Modernization Rules include the adoption of terms describing mineral reserves and mineral resources that are "substantially similar" to the corresponding terms under the CIM Definition, but there are differences in the definitions under the SEC Modernization Rules and the CIM Definition Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the mineral reserve or mineral resource estimates under the standards adopted under the SEC Modernization Rules. U.S. investors are also cautioned that while the SEC recognizes "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under the Modernization Rules, investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable. Further, "inferred mineral resources" have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, U.S. investors are also cautioned not to assume that all or any part of the "inferred mineral resources" exist. Under Canadian securities laws, estimates of "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies, except in rare cases.  For the above reasons, information contained or referenced herein regarding descriptions of our mineral reserve and mineral resource estimates is not comparable to similar information made public by U.S. companies subject to reporting and disclosure requirements of the SEC under either Industry Guide 7 or SEC Modernization Rules.
