Condor Gold plc ('Condor', 'Condor Gold' or 'the Company'): New Surface Rock Chip Results from La India Project, Including 37 g/t gold from Mestiza and 23.8 g/t from Andrea. Three Known Zones of Mineralisation Expanded.



LONDON, Oct. 3rd, 2017 /PRNewswire/ -- Condor Gold (AIM: CNR) is pleased to announce new rock chip results from the La India Project, Nicaragua, and results of detailed geological mapping, which expand three areas of known gold mineralisation. In line with the Company's strategy of proving a major gold district at the La India Project, 200 new samples have been taken from the Mestiza, Cacao and Andrea areas (see Figure 1) since December 2016 (see RNS dated 15th December 2016). All three areas have been drilled since December 2016 and these samples were collected to help extend laterally the known vein mineralisation and plan step-out drilling. Mapping was carried out at the same time.

Highlights

Mark Child, Chairman and CEO, comments:

'Condor continues its strategy of proving a major gold district at the La India Project. Mapping and rock sampling by our experienced senior geologists has produced high grade gold results of 37 g/t, 24 g/t and 16 g/t gold in three new areas, along strike from known mineralisation at Mestiza, Andrea and Cacao, which provides excellent upside potential.

Furthermore, recent drilling by Condor at Mestiza increasingly demonstrates the importance of high-grade 'oreshoots' within long, relatively continuous veins. These offer the best chance of adding high-grade economic ounces to the global resource at La India Project.

Surface rock chip sampling and trenching are the best tools at our disposal to follow up on targets identified by geophysics, geochemistry and a structural model, before making a drill decision. The northwest extension of Mestiza, where veins coalesce and intersect, is now a high priority, as is the eastern, concealed, extension of Cacao.'

Background

La India Project's existing NI 43-101-compliant mineral resource is 18 million tonnes ('Mt') at 4.0 g/t gold for 2.31 million ounces ('Moz') of gold. It comprises seven separate resources, most open along strike and at depth (Figure 1). It includes Mestiza, which hosts a NI 43-101-compliant Inferred resource of 1,490 thousand tonnes ('kt') at 7.47 g/t (333,000 ounces ('oz') gold). Here, Soviet-backed drilling in 1991 resulted in an historic, Soviet-style mineral resource of 2,392 kt at 10.2 g/t gold for 785,694 oz gold (see RNS dated 22nd May 2017). The bulk of the resource is in the Tatiana vein, the largest of the four main veins at Mestiza. Cacao has a small resource of 58,000 oz of gold, estimated in 2011. Condor completed 719 m of drilling at Cacao in December 2016 and proved a much wider vein at depth (See RNS dated 27th January 2017). Andrea was scout-drilled in the first quarter of 2017 and showed potentially economic mineralisation in the final hole (see RNS dated 31st March 2017). This was sufficient motive to explore farther east.

Note: the Andrea area lies approximately 5 km North of Mestiza

Discussion of rock chip results

Mestiza

Recent drilling at Mestiza (5922 m total; see RNS dated 30th August 2017) concentrated on Big Bend, a potential high-grade oreshoot within the Tatiana vein. The new mapping and rock chip sampling focused on the northwest extension of the Mestiza veins, beyond Big Bend. The aim was to identify new bends, vein intersections, and other potential structurally-controlled oreshoots. Figure 2, below, shows the main veins, all former rock samples, and the new rock chip results. The samples are a mix of vein outcrop and subcrop (semi in situ vein material within the soil).

Mapping has traced epithermal quartz veins over a strike length of at least 3.5 km in the Mestiza area. The topography becomes steeper and forested towards the northwest and mapping more difficult. But the Tatiana, Jícaro and Buenos Aires veins appear to coalesce into a single northwest-striking vein (Figure 2).

The new samples (Figure 2) confirm historic sampling of the northwest extension of all these veins, and include samples with 37.1, 13.9 and 27 g/t gold. These come from close to a previously reported sample of 47.7 g/t gold, about 450 m along strike from the westernmost Tatiana vein exposures.

The Espinito Vein has now been confirmed over a strike length of at least 2.6 km, and shows a jog in the Chaparro area, which seems to have higher grades (Figure 2). It hosts numerous artisanal workings and previously reported sampling gave up to 41.5 g/t gold. A series of east-northeast linking structures, with a strike length of over 300 m, occur between the southernmost part of the Espinito and Tatiana veins. These probably represent more dilational structures, exploited by mineralising fluids. Historic sampling includes 17.3 g/t gold.

Trenching of key areas is now underway at Mestiza, to help define new drill targets. New lines are being cut through thick vegetation to locate the northwest extensions of the Tatiana, Buenos Aires and Jicaro veins. They have located veins with true widths up to 3 m. Sampling is underway.

Cacao and Santa Barbara

The Cacao vein, drilled recently (see RNS dated 27th January 2017), is an east-striking quartz/carbonate vein, which flares upwards into chalcedony-rich hydrothermal breccias and a possible sinter (hot spring deposit).

New mapping demonstrates that the Cacao vein is covered in the east by a sheet of alluvial gravel, up to 20 m thick. This gravel contains blocks of chalcedonic sinter up to two metres in diameter. These blocks occur at the precise projected location of the Cacao vein, about 500 m east of the last known outcrops (Figure 3). This implies that the strike length is approximately double that known currently. Furthermore, new samples from river exposures, about 1.6 km east of the Cacao vein, again directly along strike, give values of 11.6 g/t gold (Figure 2). These also line up with new samples from Santa Barbara (Figure 3), with up to 15.8 g/t gold. Increasingly, the Cacao-Santa Barbara vein looks like a continuous corridor. Float boulders at Santa Barbara include typical high-level epithermal features, including chalcedony and bladed calcite replaced by quartz. Santa Barbara has never been drilled.

Andrea

The recent six drill holes (total 945 m) on the Andrea vein, which lies about 5 km North of Mestiza (outside Figure 1), were designed to test the structure. The final hole, in the southeast (LIDC 341) gave an intersection of 5.1 m at 1.9 g/t gold (see RNS dated 31st March 2017), suggesting improving gold grades to the southeast. Mapping and sampling were therefore extended to the southeast, an area which has never been drilled. The most promising samples, with grades up to 23.7 g/t gold, are shown in Figure 4. The sampling implies excellent potential for mineralised veins and will be followed up by trenching.

Mineral Reserve

 

 

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.

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

Phreatic breccias

Fragmental rocks formed near the Earth's surface by the interaction of hot rock and cold water, or vice versa. Commonly occur at the top of mineralized epithermal gold systems.

Rock chip

A sample of rock collected for analysis, from one or several close spaced sample points at a location. Unless otherwise stated, this type of sample is not representative of the variation in grade across the width of an ore or mineralised body and the assay results cannot be used in a Mineral Resource Estimation

Soviet Classification

 

The former Soviet system for classification of reserves and resources, developed in 1960 and revised in 1981, which divides mineral concentrations into seven categories of three major groups, based on the level of exploration performed: explored reserves (A, B, C1), evaluated reserves (C2) and prognostic resources (P1, P2, P3)

Multiple connected veins with more than one orientation, typically consisting of millimetre to centimetre thick fracture-fill veins and veinlets.

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.

Welded tuff

A fragmental volcanic rock formed by sufficiently hot volcanic ejecta that the fragments weld together

Zeolite veinlets

Zeolites are hydrated aluminosilicates found in gas bubbles within basalts and in

geothermal districts. They also found in the upper parts of gold-bearing epithermal

systems.
