"2021 was focused on drilling and advancing studies at the Camino Rojo Sulphide deposit, delivering an initial mineral resource at Caballito in Panama and defining and prioritizing drill targets across the portfolio," stated Sylvain Guerard, Senior Vice President, Exploration of Orla. "In addition to increasing reserves at the Camino Rojo Mine, efforts will be dedicated to upgrading and growing resources and drill testing priority targets with the goal of making new discoveries near existing deposits in Mexico and Panama".
Exploration spending for 2022 is expected to total $15 million, with $10 million allocated to activities in Mexico and $5 million allocated to activities in Panama. Drilling at Camino Rojo and Cerro Quema is set to begin in the second quarter and will continue through the remainder of the year. Updates from the 2022 exploration program, including drill results and updated resource estimates, are expected during the second half of 2022 and early 2023.
MEXICO EXPLORATION:
During the first year of production at the Camino Rojo Oxide mine, near-mine and regional exploration will be focused on increasing oxide reserves, supporting advancement of the sulphide deposit development scenario options, and testing priority targets defined in 2021 in an effort to make new satellite discoveries.
Camino Rojo Oxide Program:
The Company is seeking to define additional oxide reserves at the Camino Rojo Mine following confirmatory core drilling on the Fresnillo Plc's ("Fresnillo") property, located immediately north and adjacent of the Camino Rojo oxide mine open pit. While historical drilling indicates that mineralization continues across the property boundary onto the Fresnillo layback area, no ounces from this area currently included in the Camino Rojo mineral reserve estimate. The planned 2,500m diamond drill program is designed to confirm and delineate mineralization located in the oxide pit layback and allow for a potential update of mineral resource and reserve estimations.
Camino Rojo Sulphide Program – Phase 2:
Following a successful core drill program in 2021, an 8,250m follow-up drilling phase is planned in 2022 on the Camino Rojo Sulphides. The 2021 consisted of 6,079m across 14 holes on a 100-250m drill spacing at a south orientation. This program confirmed wide zones of higher-grade gold mineralization within the sulphide deposit while also providing material for new metallurgical study, which remains in progress. The 2022 program will infill drill the deposit and reduce the spacing to 50-125m. This tighter drill spacing on the more optimal south orientation, combined with the extensive south to north historical drilling, is anticipated to reinforce the geological model and confirm continuity of wide zones of higher-grade gold mineralization. This drilling is expected to support an updated resource estimate for the Camino Rojo Sulphides, and the advancement of development planning and a Preliminary Economic Assessment targeted for year end 2022.
Prior to 2021, exploration had focused on defining and expanding the Camino Rojo deposit, with limited work outside the area of the currently defined deposit and infrastructure. In 2021, regional exploration focused on defining new exploration targets using detailed airborne magnetic drone survey, induced polarization (IP) survey, and multi-elements soil geochemistry. In addition, a 9,146m, 284-hole regional rotary air blast (RAB) Cover-Bedrock Interface (CBI) program, with drill fences spaced at 1,000m and drill holes spaced at 500m along the fence, was completed to directly sample bedrock below shallow cover. Encouraging results of anomalous gold were intercepted, including 3m at 1.94 g/t Au and 44m at 0.08 g/t Au, 7 km northeast of Camino Rojo (see Figure 3). See Appendix for a summary of the anomalous results from the RAB CBI 2021 drill program.
As a result of this work, several exploration targets were defined along the Camino Rojo trend and south of the Camino Rojo Oxide Mine. These new exploration targets are hosted in rocks of the Caracol or Indidura formations, are supported by geophysical and/or geochemical anomalies, and are located at the intersection of NW-SE structures associated with the San Tiburcio Fault Zone and NE-SW trending structures on or paralleling the Camino Rojo trend. In 2022, drilling will occur on priority targets and new target generation work will also continue. A 10,000m RC drill program is planning to test the priority targets along the Camino Rojo trend and south of the Camino Rojo Oxide Mine. New deposit discovery remains the objective and this could include oxide deposits that support extension of the mine life at the Camino Rojo Oxide Mine or be additional sulphide deposits that strengthen and expand the already impressive sulphide endowment.
PANAMA EXPLORATION
The 2022 Cerro Quema exploration program will consist of infill and expansion drilling of known deposits, drill testing exploration targets defined by recent geochemical soil sampling, geophysical Induced Polarization (IP) surveys, bedrock mapping and prospecting, and historical drilling. In total, 11,700m of drilling is planned in 2022 for Panama.
Caballito Deposit Infill and Expansion Drill Program:
Infill and expansion drilling at Caballito, and more limited drilling at La Pava and Quemita, will be directed at converting resources from the inferred resource to indicated resource category, provide material for metallurgical testing, and test the continuity of mineralization and potential extensions of these deposits. The first resource estimates of copper-gold sulphide mineralization at La Pava and Quemita is planned for late 2022.
The current mineral resource estimate for the Caballito copper-gold deposit consists of the following3:

Cerro Quema Regional Exploration:
Exploration target drill testing is planned to the north of the Quemita deposit to follow-up on hole CQDH-17-112 (previously reported), which intersected 76.5m at 0.87% Cu, 0.15 g/t Au (from 68.0m to 144.5m).4
Drilling is also planned at the La Pelona target, which has a similar geophysical signature and geological context to La Pava and Quemita and has limited historical drilling. Drilling will be following up on historical drilling, which intersected oxide mineralization from surface, including 0.23 g/t Au over 138 m, and boulder samples which have returned assays of up to 1.8 g/t Au.5
South of the regional Joaquin Fault, La Prieta will also be drill tested. La Prieta is defined by a 1.4 km diameter IP chargeability anomaly with coincident Au, Cu, and Mo in-soil and in-rock geochemical anomalies which may be indicative of porphyry-style Cu-Au mineralization.
Other regional targets such as the Quemita Norte's Cu-in-soil anomaly and Monte Bonito, which is north-east of Quemita, will also be considered for drilling in 2022.

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.
