ALGOLD RESOURCES LTD. (TSX-V:ALG) today announced assay results from a trenching and pitting program carried out in late Q4 2017 at the high-grade Salma zone located at the Corporation’s Tijirit project in Mauritania.
The Salma Vein, discovered in mid-2017 (reference Algold’s press release dated June 7, 2017), is located only five kilometers northeast of the Eleonore zone. The Salma zone vein system has now been traced over a ten-kilometer-long mineralized gold structure situated at the prospective granite-greenstone contact zone.
“These results highlight the extensive potential of the Salma zone to rapidly add substantial high-grade gold mineralization at the Tijirit project,” said Algold CEO, Francois Auclair. “We continue to focus on building and expanding existing resources at Tijirit, which now consists of three larger main mineralized zones (Eleonore, Lily and Salma), all in close proximity, thus enabling many future operating synergies.”
Sampling was carried out predominantly in trenches and pits excavated by artisanal miners. Compliance with on-site safety protocol limited entry by Algold geologists to only certain trenches and pits for sampling purposes. The samples were generally taken at depths varying from 3 to 5 meters in trenches (or pits) that demonstrated higher grade or wider mineralization and that received limited work compared to other areas. (Reference Algold’s press release dated December 6, 2017, Figure 1 and Photo 1: an artisanal pit where access was prohibited.)
The material sampled in pits often included unmined narrow “pillars” with exposed veins, albeit presumably narrower than that what had been mined. The ends of pits, where the mineralization had seemingly pinched out, were also sampled to confirm the hypothesis as well as to provide better targeting for future drilling.
Throughout the Salma zone the mineralization trends in a north to northeast direction and is associated with local shearing. Gold was found within quartz veins ranging in width from 0.2 to 3.25 meters, located close to the contact of an intrusive granite pluton and the mafic volcanics. Locally, veins pinch and swell along the structure. Individual veins have been mapped for over 500 meters, with parallel veins often recorded. In the southern Salma zone, in the area dubbed Pressure Shadow, various orientations were observed with flat-lying, shallow dipping, discordant and shear-associated veins recorded. Gold has been found in all of these structures.
In total, 78 trenches were sampled with 276 channel samples taken from 180.5 meters.

Salma Vein System and Pressure Shadow Area Channel Sampling
Continuous channels were sampled, honouring geological contacts, using hammer and chisel with care taken to avoid sampling bias. Once collected, samples were dried, crushed and split with one kilogram pulverised and sent to SGS Ouagadougou for bottle roll analysis using LeachWELL assay tabs.
As of December 31, 2017, Algold had collected 21,332 samples (excluding QA/QC) as part of the Phase III drilling program. At present, Algold is in receipt of 20,660 assay results, with 665 drill samples still pending (excluding QA/QC).
Quality Assurance / Quality Control
Analytical work for drill core and chips, geochemical samples and rock chip samples is carried out at the independent SGS Laboratories Ltd. in Bamako, Mali. The 50-gram fire assay with ASS finish analytical services are accredited by SANAS and are carried out with a quality assurance protocol in line with ISO 17025:2005. Samples are stored at the Corporation’s field camps and put into sealed bags until delivered by a geologist on behalf of Algold to the laboratory in Bamako, Mali, where samples are prepared and analyzed. Until the end of 2016, samples were analyzed at ALS’s facility in Loughrea, Ireland. Beginning in 2017, samples are analyzed at SGS Laboratory, Bamako. Samples are logged in the tracking system, weighed, dried and finely crushed to better than 70%, passing a 2 mm (Tyler 9 mesh, US Std. No.10) screen. A split of up to 1,000 grams is taken and pulverized to better than 85%, passing a 75-micron (Tyler 200 mesh) screen, and a 50-gram split is analyzed by fire assay with an AA finish. Anomalous samples greater than 5 g/t Au are re-analyzed by 50-gram fire assay with gravimetric finish. Selected samples may be re-analyzed using a 1-kilogram cyanide leach (Bottle Roll) using “LeachWELL” or the 1-kilogram screen fire assay method. Blanks, duplicates and certified reference material (standards) are inserted to monitor laboratory performance during the analysis.
