8,004 m Infill Drilling Completed at the Fully Permitted La Mestiza Open Pit
SURREY, BC / ACCESSWIRE / October 21, 2021 / Condor Gold (AIM:CNR)(TSX:COG)(OTC PINK:CNDGF) is pleased to announce completion of an 8,004 m infill drilling programme on the fully permitted high-grade La Mestiza Open Pit Mineral Resource at La India Project, Nicaragua. The drilling programme has tightened drill spacing to 25 m along strike and 50 m down-dip in the zones that have the potential to support open pit mine development. The drilling is expected to upgrade the existing open pit gold mineral resource to the indicated category for the potential inclusion in future pre-feasibility or feasibility studies of the Company's fully permitted La India Gold Mine Development Project.
Highlights:
- Ninety-six diamond core drill holes for 8,004 m infill drilling was completed on the high-grade La Mestiza Open Pit.
- La India Open Pit has an open pit mineral resource of 92 kt at 12.1 g/t gold for 36,000 oz gold in the Indicated category and 341 kt at 7.7 g/t gold for 85,000 oz gold in the in the Inferred category
- La Mestiza Open Pit containsan estimated fully diluted mill feed of 499Kt at 5.37g/t gold for 86,000 oz gold in the September 2021 PEA and is targeted for early extraction.
- The tighter drill spacing is aimed to upgrade the open pit gold mineral resource to the indicated category for the potential inclusion in future pre-feasibility or feasibility studies.
- The Mestiza vein set remains open down dip and along strike in both directions, has parallel veins identified by rock chip sampling and trenching and has the potential for further significant discovery.
Mark Child, Chairman and CEO commented:
"The completion of 8,004 m of infill drilling on the fully permitted La Mestiza Open Pit is another milestone achieved in de-risking the La India Project ahead of production. Condor already has monthly mine schedules for this open pit as it is targeted for early extraction. The focus of the infill drilling is to convert the Inferred material to the higher category Indicated Mineral Resource. Drill results so far have been consistent with previous drilling grades and widths, demonstrating good continuity in gold mineralization between adjacent drill holes in the high grade zones, for example, 4.1 m true width at 15.23 g/t gold from 47.80 m (drill hole LIDC514) approximately 40 m below surface. 3.6 m true width at 29.1 g/t gold from 105.70 m (drill hole LIDC471) approximately 85 m below surface. 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 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."
Background
The Mestiza vein set is located only 3 km from the permitted processing plant on Condor's La India Gold Mine Development Project (see Figure 1). Prior to the latest infill drilling campaign, between 2010 and 2017 Condor drilled 53 drill holes for 7,688 m and estimated a mineral resource comprising:
- an open pit mineral resource of 92 kt at 12.1 g/t gold for 36,000 oz gold in the Indicated category and 341 kt at 7.7 g/t gold for 85,000 oz gold in the in the Inferred category, and
- an underground mineral resource of 118 kt at 5.5g /t gold in the Indicated category and 984 kt at 5.3 g/t gold for 169,000 oz gold in the Inferred category (Table 1 below).
Open pit mining scenarios based on the combined inferred and indicated open pit mineral resource at La Mestiza envisage a fully diluted mill feed of 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 studies were undertaken by SRK Consulting (UK) Limited as part of the project-wide Preliminary Economic Assessment ("PEA") announced in an RNS dated the 9th September 2021. The 2021 PEA Technical Report will be issued within 45 days of the public disclosure in compliance with NI 43-101 standards.
Latest infill drilling
Between May and October this year, Condor drilled 96 diamond core drill holes for 8,004 m. The infill drill programme has tightened (drill) spacing from 50 m to 100 m spacing to a regular 25 m along strike and 50 m down-dip in the areas that that are considered to have the highest potential to support open pit mining. Infill drilling focussed on the 85,000 oz gold that is currently categorised as Inferred Mineral Resource. If successful, the Company is aiming to convert the Inferred category mineral resources to the higher confidence Indicated category, and their potential inclusion in future pre-feasibility or feasibility mining studies. Assay results received to date have beenconsistent with previous drilling grades and widths, demonstrating good continuity in gold mineralization between adjacent drill holes in the high grade zones andadding confidence to the geological model (see RNS dated 24th September 2021). Drilling highlights were 4.1 m true width at 15.23 g/t gold from 47.80 m (drill hole LIDC514) approximately 40 m below surface. 3.6 m true width at 29.1 g/t gold from 105.70 m (drill hole LIDC471) approximately 85 m below surface
When all assay results have been received the infill drilling data will be incorporated in an updated geological model and mineral resource estimation.

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.

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 |
| ARDML | Acid rock drainage and metal leaching |
| Au | Gold |
| Diamond core drilling | A drilling method in which penetration is achieved through abrasive cutting by rotation of a diamond encrusted drill bit. This drilling method enables collection of tubes of intact rock (core) and when successful gives the best possible quality samples for description, sampling and analysis of an ore body or mineralised structure. |
| 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, |
| IRR | The Internal Rate of Return (IRR) is the discount rate that makes the net present value (NPV) of a project zero. In other words, it is the expected compound annual rate of return that will be earned on a project or investment |
| Kt | Thousand tonnes |
| Mineral Resource Estimate | 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. |
| Mineral Reserve | An ‘Ore Reserve' is the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined. Appropriate assessments and studies have been carried out, and include consideration of and modification by realistically assumed mining, metallurgical, economic, marketing, legal, environmental, social and governmental factors. These assessments demonstrate at the time of reporting that extraction could reasonably be justified. Ore Reserves are sub-divided in order of increasing confidence into Probable Ore Reserves and Proved Ore Reserves. |
| NI 43-101 | Canadian National Instrument 43-101 a common standard for reporting of identified mineral resources and ore reserves |
| NPV | Net Present Value (NPV) is the value of all future cash flows (positive and negative) over the entire life of an investment discounted to the present. NPV analysis is a form of intrinsic valuation and is used extensively across finance and accounting for determining the value of a business, investment security, capital project, new venture, cost reduction program, and anything that involves cash flow. It is after deducting the upfront capital cost |
| 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). |
| 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. |
