Condor Gold Plc: 60.60 m (54.5 m true width) at 1.98 g/t gold, Near Surface
Incl. 5.75 m (5.2 m true width) at 16.88 g/t gold within the Fully Permitted La India Open PitSURREY, July 21, 2021 - Condor Gold (AIM:CNR)(TSX:COG) is pleased to announce assay results from a further twelve diamond core drill holes located between and along strike of the planned high-grade La India Starter Pits, which sit within the fully permitted La India Open Pit Mineral Reserve Estimate of 6.9Mt at 3.1 g/t gold for 675,000 oz gold. The Company is encouraged by higher than expected grades in three of the drill holes, particularly as two high grade, wide intercepts are between the two starter pits in an area previously interpreted as having lower grade gold mineralisation. These results will be incorporated into a revised feasibility-level mine plan and are expected to have a positive impact on the Project's economics.
Highlights of New Drill Assay Results
- 60.60 m (54.5 m true width) at 1.98 g/t gold from 4.15 m drill depth, including 5.75 m (5.2 m true width) at 16.88 g/t gold from 42.55 m drill depth in drill hole LIDC452 located between the two proposed starter pits.
- The wide zone of gold mineralization near surface has the potential to reduce the strip ratio in this area due to the increase in gold mineralized tonnage verse waste rock, thus improving Project economics.
- 3.75 m (3.4 m true width) at 9.94 g/t gold from the hanging wall of the historic mine workings in drill hole LIDC454 located between the two starter pits.
- Potential to amalgamate the two Starter Pits into a single, larger Starter Pit as a broad zone of high grade gold mineralization was previously interpreted as a low grade zone with the main La India open pit.
- 9.00 m (8.5 m true width) amalgamated width at 4.98 g/t gold from 55.05 m drill depth in the hangingwall and footwall of the historic mine workings, including 5.35 m (5.0 m true width) at 6.61 g/t in the hangingwall of drill hole LIDC456. This drill intercept is located to the south and below the Southern Starter Pit.
Mark Child, Chairman and CEO commented:
"The high grade, wide, drill assay results between the two La India Starter Pits are a positive surprise as this area was previously interpreted as a lower grade zone within the main fully permitted La India open pit. LIDC452 returned 60.60 m (54.5 m true width) at 1.98 g/t gold from 4.15 m drill depth, including 5.75 m (5.2 m true width) at 16.88 g/t gold. Mine schedules will be re-run to determine whether the two Starter Pits can be amalgamated into one Starter Pit and thus provide additional high grade mill feed from surface. Furthermore, the broad zone of mineralization is likely to reduce the overall strip ratio for the main La India open pit, as there is more mineralized gold tonnage verses waste rock, thus potentially improving the Project's economics.
The drill results strengthen the case for expanding the Starter Pits, which are within 35 m of the surface and contain approximately 455Kt at 4.17g/t gold for 59,674 oz gold using a 2.00g/t cut off grade. The intention is to mine the Starter Pits early to quicken the payback period. The Starter Pits sit within the main fully permitted La India open pit, which has a Mineral Reserve Estimate of 6.9Mt at 3.1 g/t gold for 675,000 oz gold".
Background
Following the recent completion of a 25 m-spaced infill and reverse circulation (RC) replacement drilling on the La India Starter Pits (see RNS dated 5th July 2021), a programme of diamond core drilling to replace 90% of the remaining RC drill holes that fall within the main La India open pit shell was completed. A total of twenty-three RC drill holes (for 1632.05 m) were twinned by diamond core drilling, including both those that intercepted mineralisation within and adjacent to the high-grade starter pits, as well as holes drilled in lower grade zones further along strike and beneath the high-grade starter pits.
The current open-pit Mineral Resource partially relies upon chip samples from RC drilling. Whilst it is generally recognised that RC drilling provides reliable gold-grade data at regular metre-scale sample intervals suitable for inclusion in an open-pit Mineral Resource estimation, better and more detailed geological information on the structures that contain the gold mineralised veins and breccia is provided by diamond core drilling. This additional data will further enhance the current Mineral Resources and Mineral Reserves and be utilised in final mine schedules.
Latest Assay Results
Results for many of the RC-twin drill holes that occur within or near to the starter pits were reported in a RNS update dated 5th July 2021. Results for a further twelve diamond core drill holes from for a total of 844.15 m that twinned RC holes between, along strike and below the starter pits, but within the main La India open pit shell have been received. The Company is encouraged that these include three significant drill intercepts in two zones that were previously modelled as lower grade zones largely depleted by historic mining; two were drilled in what was considered low-grade zone between the two Starter Pits and one was drilled along to the south of the Southern Starter Pit:
- 60.60 m (54.5 m true width) at 1.98 g/t gold from 4.15 m drill depth, including 5.75 m (5.2 m true width) at 16.88 g/t gold from 42.55 m drill depth in drill hole LIDC452 located between the two proposed starter pits.
- 3.75 m (3.4 m true width) at 9.94 g/t gold from the hanging wall of the historic mine workings in drill hole LIDC454 located between the two starter pits.
- 9.00 m (8.5 m true width) amalgamated width at 4.98 g/t gold from 55.05 m drill depth in the hangwall and footwall of the historic mine workings, including 5.35 m (5.0 m true width) at 6.61 g/t in the hangingwall of drillhole LIDC456. This drill intercept is located to the south and below the Southern Starter Pit.
Looking Ahead
Condor is very encouraged by these high-grade, high width drilling intercepts and will assess whether the starter pits can be extended along strike and to depth, and possibly amalgamated into one larger starter pit. An updated mineral resource and mineral reserve estimation and revised mine plan will be produced at feasibility level of detail using these new results along with the recent 25 m-spaced infill drilling.

Notes:
- The sample chain of custody is managed by the Condor's Geology Team on site. Reported results are from diamond drilled core samples. Intervals of core to be analysed are split into half using a mechanized core cutter, with one half sent to the Laboratory for geochemical analysis and the remaining half kept in storage for future reference and uses. Diamond drilled core has been a HQ size and recoveries are consistently 100% across all drill holes intercept reported.
- Sampling and analytical procedures are subject to a comprehensive quality assurance and quality control program. The QAQC program involves insertion of duplicate samples, blanks and certified reference materials in the sample stream. Gold analyses are performed by standard fire assaying protocols using a 50-gram charge with atomic absorption (AAS) finish and a gravimetric finish performed for assays greater than 10 grams per tonne.
- Sample preparation and analysis are performed by the independent Bureau Veritas Laboratories, Canada. Samples are crushed and prepared in Managua and pulp samples for fire assay are dispatched to Vancouver, Canada. The Laboratory meets the requirements of ISO/IEC 17025 & ISO 9001, and employs a Laboratory Information Management System for sample tracking, quality control and reporting.
About the Starter Pits
On 25 January 2019, SRK Consulting (UK) Limited completed an updated Mineral Resource Estimate (the "MRE"; see RNS dated 28 January 2019) on Condor's 100% owned La India Project in Nicaragua comprising 9.85 million tonnes ("M tonnes" or "Mt") at 3.6 g/t gold for 1,140,000 oz gold in the Indicated category and 8.48M tonnes at 4.3g/t gold for 1,179,000 oz gold in the Inferred category.
The La India Vein Set hosts an open pit Mineral Resource of 8,377 kt at 3.1 g/t gold for 837 Koz gold in the Indicated category and 887 kt at 2.4 g/t gold for 69,000 oz gold in the Inferred category. Beneath the La India open pit is an underground Mineral Resource estimate of 678 kt at 4.9 g/t gold for 107 Koz gold in the Indicated category and 1,718 kt at 5.6 g/t gold for 309,000 oz gold in the Inferred category.
The 25 January 2019 MRE update did not materially change the La India open pit Mineral Resource estimate and consequently the 2014 Pre-Feasibility Study ("PFS") remained unchanged. La India open pit has an existing Probable Mineral Reserve of 6.9 million tonnes ("Mt") at 3.01 g/t gold for 675,000 oz gold.
As announced on 4 March 2020 (see RNS), Condor completed internal studies on readily accessible high-grade material within the permitted La India open pit. The starter pits within La India open pit contain a diluted tonnage of 387 Kt at 4.29 g/t gold for 53,000 oz gold. Condor has subsequently further advanced these studies. Within a designed pit shell, the starter pits have two scenarios. At 0.75 g/t gold cut-off grade, 635 Kt at 3.32 g/t gold for 67,800 oz gold with a 4.5 to 1 strip ratio. Using a 2.0 g/t cut-off grade, 445 Kt at 4.17 g/t gold for 59,700 oz gold with a 6.8 to 1 strip ratio. See table 1 below:
Table 2: Starter Pits within the Main Permitted La India Open Pit
About the Drilling Techniques
Drilling was undertaken using heavy duty track-mounted drilling rigs. All of the drilling was undertaken using diamond core drilling techniques employing large diameter PQ core barrels and triple tube in the mineralised zones to ensure good sample recovery. Drilling close to surface and in proximity to historical and artisanal mine workings can present challenges to the driller, however, the drilling programme benefitted from employment of local geologists, field support staff and experienced drill contractors, all with a decade of experience of drilling at la India. Consequently, all target depths were met and good sample recovery was achieved.
About the Assaying
Drill core was cut, and half core samples collected and bagged by Condor staff on-site. Samples were transported to Bureau Veritas accredited sample preparation laboratory in Managua every week in batches of two or three drill holes, generally being submitted to the lab within 5-10 days of completing the drill hole. Sub-samples of the pulverised rock samples were forwarded for assay to Bureau Veritas accredited analytical laboratory in Vancouver, Canada.

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.

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). |
| 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. |
