SURREY, UK / ACCESSWIRE / September 24, 2021 / Condor Gold (AIM:CNR)(TSX:COG) is pleased to announce that the first phase of infill drilling of 39 drill holes for 3371.58 metres using diamond core drilling has been completed on the Mestiza Open Pit and all assay results received. The results of the infill drilling are consistent with previous drilling grades and widths, demonstrating good continuity in gold mineralization between adjacent drill holes in the high grade zones and add confidence to the geological model. The total drilling programme on Mestiza Open Pit is approximately 7800 metres, 2 drill rigs are operating on site, the drilling should be completed within 6 weeks. The primary objective of the drill programme is to convert the Inferred Mineral Resource to a higher level of confidence Indicated Mineral Resource for inclusion in an economic Mineral Reserve and prepare the permitted Mestiza Open Pit for extraction.

The total drilling programme on Mestiza Open Pit is approximately 7800 metres, 2 drill rigs are operating on site, the drilling should be completed within 6 weeks.
Mestiza Open Pit has currently estimated fully diluted feed mill feed in the September 2021 PEA of 499Kt at 5.37g/t gold for 86,000 oz gold and is targeted for early extraction.
Mark Child, Chairman and CEO commented:
"I am delighted with the initial results of the 7800 metre infill drilling programme on our permitted high grade Mestiza Open Pit, which is targeted for early production. The high grade drill intercepts announced today of 4.1 m true width at 15.23 g/t gold and 3.6 m true width at 29.1 g/t gold, approximately 40 m and 85 m respectively below surface may add to our mineral resource inventory at Mestiza and possibly improve the Project's economics, although this will only be confirmed at the conclusion of this drilling campaign.
The September 2021 PEA estimated the Mestiza Open Pit can currently deliver a fully diluted mill feed of 499Kt at 5.37g/t gold for 86,000 oz gold. The tighter drill spacing has delivered relatively shallow, high grade drill intercepts which add considerable confidence to the existing monthly mine schedules".
About the Mestiza Open Pit
The Mestiza Open Pit sits within the La Mestiza Vein Set, which host a high grade open pit Mineral Resource Estimate ("MRE") of 432kt at 8.6g/t gold (92kt at 12.1g/t gold for 36,000 oz gold in the Indicated Category and 341kt at 7.7 g/t gold for 85,000 oz gold in the in the Inferred Category), and an underground Mineral Resource of 118kt at 5.5g/t gold in the Indicated category and 984kt at 5.3 g/t gold for 169,000 oz gold in the Inferred category (see RNS dated 28 January 2019 and Table 1 below). The Mestiza Vein Set is part of Condor's 100% owned La India Project (the "Project").
On 9 September 2021, Condor announced the key findings of a technical report on the Project prepared by SRK Consulting (UK) Limited ("SRK"). This technical report (the "Technical Report") presents the results of a strategic mining study to Preliminary Economic Assessment ("PEA") standards completed on the Project in 2021 (See RNS dated 9 September 2021). The 2021 PEA Technical Report will be issued within 45 days of the public disclosure to NI 43-101 standards. The PEA includes open pit mining scenarios containing mill feed from the Mestiza Open Pit. The estimated fully diluted feed mill feed for the PEA is 499Kt at 5.37g/t gold for 86,000 oz gold. Assuming a 91% metallurgical recovery and a gold price of US$1700 per oz, gold production would be 78,260 oz gold and revenues US$133M.
The Mestiza Vein Set is located only 3 km from the permitted processing plant on Condor's La India Project, comprises of several gold-bearing quartz veins spread across an 800 m wide corridor, and striking for 1500 m to 2000 m in north-northwest to south southeast direction along the top of a broad ridge (see Figure 1). The gold mineralised veins are contained within steep-dipping faults and to a lesser extent as breccia and stockwork veinlets within fracture zones on the walls of the faults. The gold mineralisation is best developed where the host rock on both sides of the fault is a hard, welded volcanic tuff. The high-grades occur with the faults where early quartz veins and quartz breccias have been ground to fault breccia, quartz sands or even fault clays by movement along the fault planes. A later stage, post-fault quartz mineralisation is recognised in some places overprinting the fault breccias and sands. The gold mineralisation is interpreted to be associated with both phases of quartz development.
The La Mestiza Vein Set is open along strike and down dip and has parallel veins identified by rock chip sampling, which are outside the area of Mestiza Vein Set's MRE. The MRE of the deposit can potentially be increased in size with further drilling.

About the Infill Drilling
The first phase of 3371.58 m of infill drilling has ‘tightened-up' the drill spacing from a mix of 50 m to 100 m spacing to a regular 50 m along strike and 50 m down-dip grid. A second phase of approximately 4500 m of infill drilling to 25 m along strike and 50 m down-dip spacing is currently underway in the area of the principal open pit resource on the Tatiana Vein. The objective of the drilling program is to further improve the confidence of the geological model and future mine schedules, aiming to upgrade a significant proportion of the 85,000 oz gold open pit MRE in the Inferred category to the Indicated category.
Discussion of the Assay Results
Assay results are generally consistent with the previous wider spaced drilling. High-grade gold intercepts have been returned from the drill holes that infill between previous high-grade intercepts, and are interpreted to demonstrate good continuity of gold mineralization in the area. (Table 1 below shows the top 8 drill intercepts to-date). The Company notes that the best drill intercept from Mestiza Open Pit to-date has been of returned at the base of the principal open pit with 3.90 m (3.6 m true width) at 29.1 g/t gold from 105.70 m in drill hole LIDC471. This is supported approximately 50 m up-dip and 25 m along strike by an intercept of 4.5m (4.11m true width) at 15.23g/t gold from 47.8m drill depth (drill hole LIDC514). The second phase of infill drilling to 25 m along strike by 50 m down-dip drill sample spacing in the areas of the open pits is underway with the goal to add further confidence to the geological model and mineral resource estimate.

(1) The Mestiza pits are amenable to open pit mining and the Mineral Resource Estimates are constrained within Whittle optimised pits, which SRK based on the following parameters: A Gold price of USD1,500 per ounce of gold with no adjustments. Prices are based on experience gained from other SRK Projects. Metallurgical recovery assumptions of 96% for gold are based on testwork conducted to date. Marginal costs of USD19.36/t for processing, USD5.69/t G&A and USD2.35/t for mining, slope angles defined by the Company Geotechnical study of 45°, haul cost of USD1.25/t was added to the Mestiza ore tonnes to consider transportation to the plant.
(2) Underground mineral resources beneath the open pit are reported at a cut-off grade of 2.0 g/t over a minimum width of 1.0m. Cut-off grades are based on a price of USD1,500 per ounce of gold and gold recoveries of 91 percent for resources, costs of USD19.36/t for processing, USD4.55/t G&A and USD50.0/t for mining, without considering revenues from other metals.
(3) Mineral Resources are not Ore Reserves and do not have demonstrated economic viability. All figures are rounded to reflect the relative accuracy of the estimate and have been used to derive sub-totals, totals and weighted averages. Such calculations inherently involve a degree of rounding and consequently introduce a margin of error. Where these occur, SRK does not consider them to be material. All composites have been capped where appropriate. The Concession is wholly owned by and exploration is operated by Condor Gold plc
(4) The reporting standard adopted for the reporting of the MRE uses the terminology, definitions and guidelines given in the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Mineral Reserves (May 2014) as required by NI 43-101.
(5) SRK Completed a site inspection to the deposit by Mr Benjamin Parsons, MSc (MAusIMM(CP), Membership Number 222568, an appropriate "independent qualified person" as this term is defined in National Instrument 43-101.

About Condor Gold plc:
Condor Gold plc was admitted to AIM in May 2006 and dual listed on the TSX in January 2018. The Company is a gold exploration and development company with a focus on Nicaragua.
In August 2018, the Company announced that the Ministry of the Environment in Nicaragua had granted the Environmental Permit ("EP") for the development, construction and operation of a processing plant with capacity to process up to 2,800 tonnes per day at its wholly-owned La India gold project ("La India Project"). The EP is considered the master permit for mining operations in Nicaragua.
La India Project contains a Mineral Resource of 9,850 Kt at 3.6 g/t gold for 1.14 M oz gold in the Indicated category and 8,479 Kt at 4.3 g/t gold for 1.18 M oz gold in the Inferred category. A gold price of $1,500/oz and a cut-off grade of 0.5 g/t and 2.0 g/t gold were assumed for open pit and underground resources, respectively. A cut-off grade of 1.5 g/t gold was furthermore applied within a part of the Inferred Resource. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that any part of the Mineral Resources will be converted to Mineral Reserves.
Environmental Permits were granted in April and May 2020 for the Mestiza and America open pits respectively, both located close to La India. The Mestiza open pit hosts 92 Kt at a grade of 12.1 g/t gold (36,000 oz contained gold) in the Indicated Mineral Resource category and 341 Kt at a grade of 7.7 g/t gold (85,000 oz contained gold) in the Inferred Mineral Resource category. The America open pit hosts 114 Kt at a grade of 8.1 g/t gold (30,000 oz) in the Indicated Mineral Resource category and 677 Kt at a grade of 3.1 g/t gold (67,000 oz) in the Inferred Mineral Resource category. Following the permitting of the Mestiza and America open pits, together with the La India open pit Condor has 1.12 M oz gold open pit Mineral Resources permitted for extraction.

Indicated Mineral Resource
That part of a Mineral Resource for which tonnage, densities, shape, physical characteristics, grade and mineral content can be estimated with a reasonable level of confidence. It is based on exploration, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes. The locations are too widely or inappropriately spaced to confirm geological and/or grade continuity but are spaced closely enough for continuity to be assumed.
Inferred Mineral Resource
That part of a Mineral Resource for which tonnage, grade and mineral content can be estimated with a low level of confidence. It is inferred from geological evidence and assumed but not verified geological and/or grade continuity. It is based on information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that may be limited, or of uncertain quality and reliability,
Originally a miner's term to refer to the rock above the mineralised zone that they exploited. Now often used to refer to the rock adjacent to and above an ore or mineralised body or geological fault.

Open pit mining
A method of extracting minerals from the earth by excavating downwards from the surface such that the ore is extracted in the open air (as opposed to underground mining).
Deposit of quartz rock that develop in fractures and fissures in the surrounding rock. They are deposited by saturated geothermal liquids rising to the surface through the cracks in the rock and then cooling, taking on the shape of the cracks that they fill.
Multiple connected veins with more than one orientation, typically consisting of millimetre to centimetre thick fracture-fill veins and veinlets.
The longest horizontal dimension of an ore body or zone of mineralisation.
A sheet-like body of crystallised minerals within a rock, generally forming in a discontinuity or crack between two rock masses. Economic concentrations of gold are often contained within vein minerals.
