SURREY, UK / ACCESSWIRE / June 10, 2021 / Condor Gold (AIM:CNR; TSX:COG) is pleased to announce that is has commenced an 8,500 metre infill diamond drilling programme within the permitted La Mestiza Open Pit Mineral Resource at La India Project, Nicaragua. Two diamond core drill rigs are currently operating on Mestiza and have drilled approximately 600 metres to date. The programme is anticipated to take a further 4 months to complete. Condor is also pleased to provide updated preminarly mine schedules on La Mestiza Open Pits conducted by SRK Consulting (USA) Inc, based on the existing Mineral Resource and in support of the 8,500 metre drilling programme.
Highlights
- Existing La Mesitza Open Pit Mineral Resource hosts 433kt at 8.6g/t gold for 120,000 oz gold (92kt at 12.1 g/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 Inferred Category).
- 8,500m infill drilling programme has commenced on the high-grade La Mestiza Open Pit aimed at upgrading Mineral Resources to Indicated category such that it forms a basis for inclusion into future Pre-Feasibility or Feasibility Studies .
- The Mestiza Vein Set is open down dip and along strike and has the potential for a material increase with additional drilling.
- Preliminary mine schedules indicate the potential to deliver 499kt of high grade material to the processing plant at a diluted head grade of 5.37 g/t gold, with the potential to produce 86,000 oz gold.
Mark Child, Chairman and CEO commented:
"Following the purchase of a new SAG mill package in April 2021, Condor engaged SRK Consulting (USA) Inc to produce strategic mine schedules on the high-grade fully permitted La Mesitza Open Pit Mineral Resource, which hosts 433kt at 8.6g/t gold for 120,000 oz gold (92kt at 12.1 g/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). The schedules developed indicate a potential feed to the processing plant estimated at 499kt, at a diluted head grade of 5.37 g/t gold with potential to produce 86,000 oz gold. The aim of the 8,500m infill drilling programme in La Mestiza open pit is to convert a significant proportion of the Inferred Mineral Resource to an Indicated Mineral Resource for inclusion in future Pre-Feasibility Study or Feasibility Studies, enhance the geological confidence, de-risk future mine plans and attract project financing."
Drill Programme
The current Mineral Resource estimate dated 25 January 2019 (see RNS dated 28 January 2019 and Table 1 below) on the Mestiza Vein Set defines an open pit Mineral Resource 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. The 8,500 metres infill drilling programme will target the part of the Mineral Resource that is considered to have the potential to support open pit mining, focussing on the 85,000 oz gold that is currently catagorised as Inferred. The drilling will ‘tighten up' the drill spacing from the current mix of 50 m to 100 m spacing to a regular 25 m along strike and 50 m down-dip. The objective of the drilling program is to improve the confidence of the geological model and future mine schedules, aiming to upgrade a significant proportion of the Inferred open pit Mineral Resource to the Indicated Mineral Resource category for use in future Pre-Feasibility or Feasibility level studies.
The Mestiza Vein Set is located only 3 km from the permitted processing plant on La India Project (see Figure 1). The Mestiza Vein Set is open along strike and down dip and has the potential to be materially increased with further drilling.
Drilling will be accomplished with a combination of PQ and HQ diamond drilling bits, with half-core samples shipped to Bureau Veritas in Managua for sample prep and to Bureau Veritas' facilties in Vancouver, B.C. for assaying.

| (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. | |||||||||

Mesitza Open Pit Mine Schedules
SRK Consulting (USA) Inc has recently produced strategic mine schedules based on the fully permitted La Mestiza Open Pit Mineral Resource, as detailed above. The study has looked to optimise the potential material exploitable by open pit mining methods acting as a strategic planning tool for the Company. The updated study has expanded on the separation of the ultimate pit by phase, now representing 9 phases compared to 4 phases previously envisioned. The phase design assumptions include: 40 to 42 overal pit angles, 10m road width, 5 m benches with 2.5 m flitches, waste mined at 10m benches. Various production rates were considered with a 500tpd schedule with low grade stockpiling assessed to produce the best stand alone economics.
Under the study, ore tonnes delivered to the processing plant are 499kt, the diluted head grade is 5.37 g/t gold, waste tonnes 13,257kt. The study assumed the same mining costs of US$2.57 per tonne for both ore and waste mining and processing costs of US$27.30 per tonne. The resultant potential cashflows being considered highly attractive by Condor.
It should be noted that these mining scenarios are part of ongoing work being done by Condor to optimize the Project which has not yet been finalized and so do not replace the 2019 MRE or the technical report entitled "Technical Report on the La India Gold Project, Nicaragua, December 2014" dated 13 November 2017 with an effective date of 21 December 2014 (the "Technical Report"), both of which remain current.
The tonnages, grades and contained gold estimates included in this are based on the mining of the existing, and previously reported Indicated and Inferred Mineral Resources which have been factored to include mining losses and dilution.

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. Condor Gold published a Pre-Feasibility Study ("PFS") on the project in December 2014, summarised in the Technical Report, as defined below. The PFS details an open pit gold Mineral Reserve in the Probable category of 6.9 Mt at 3.0 g/t gold for 675,000 oz gold, producing 80,000 oz gold per annum for 7 years. La India Project contains a Mineral Resource of 9,850 Kt at 3.6 g/t gold for 1.14 Moz gold in the Indicated category and 8,479 Kt at 4.3 g/t gold for 1.18 Moz gold in the Inferred category. The Indicated Mineral Resource is inclusive of the Mineral Reserve. 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 Moz gold open pit Mineral Resources permitted for extraction, inclusive of a Mineral Reserve of 6.9 Mt at 3.0 g/t gold for 675,000 oz gold.

Technical Glossary
| Assay | The laboratory test conducted to determine the proportion of a mineral within a rock or other material. Usually reported as parts per million which is equivalent to grams of the mineral (i.e. gold) per tonne of rock |
| Ag | Silver |
| Au | Gold |
| Down-dip | Further down towards the deepest parts of an ore body or zone of mineralisation. |
| Grade | The proportion of a mineral within a rock or other material. For gold mineralisation this is usually reported as grams of gold per tonne of rock (g/t) |
| g/t | grams per tonne |
| 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, |
| Kt | Thousand tonnes |
| Mineral Resource | A concentration or occurrence of material of economic interest in or on the Earth's crust in such a form, quality, and quantity that there are reasonable and realistic prospects for eventual economic extraction. The location, quantity, grade, continuity and other geological characteristics of a Mineral Resource are known, estimated from specific geological knowledge, or interpreted from a well constrained and portrayed geological model. |
| NI 43-101 | Canadian National Instrument 43-101 a common standard for reporting of identified mineral resources and ore reserves |
| 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). |
| Recovery (drilling) | The percentage of the length of rock that is brought to the surface surface by drilling. The rock samples are typically brought to the surface in 1m to 3m long sections and the recovery is expressed as a percentage of the length of each section. |
| Strike length | The longest horizontal dimension of an ore body or zone of mineralisation. |
| Vein | 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. |
