MONTREAL, Nov. 02, 2017 (GLOBE
NEWSWIRE) -- ALGOLD RESOURCES
LTD. (TSXV:ALG) (the
"Corporation") today announced results of expanded
metallurgical tests results from drill core samples at the Tijirit
project ("Tijirit") in Mauritania, and these tests continue to
demonstrate Tijirit's exploration and mining potential. Following
the positive testworks results completed in 2016 (see Press Release
dated January 18, 2017), Algold conducted additional metallurgical
work which consisted of grinding and cyanidation testing at SGS
Lakefield.
Metallurgical testing were carried
out at SGS Lakefield Laboratory (Ontario) on 16 composites using
diamond drill hole core samples collected from the Eleonore (South,
Central, North), Sophie II, and Lily Zones. The Eleonore composite
was characterized by quartz veins associated with meta-sediments,
metavolcanics or porphyries units. The Sophie II composite was made
up of quartz veins within banded iron formation ("BIF") and
amphibolite and the Lily composite was made up of metasediments.
Each composite weighted between 3 kg and 10 kg.
Recovery of gold amenable to
gravity separation followed by cyanidation of the gravity tailings
was conducted with the following results. Those tesworks have been
conducted based on the same optimum conditions which were
determined during the first program (2016-2017).

"These expanded metallurgical
tests are very encouraging and confirm and build on the tests
completed in 2016-2017. The testworks wich were performed on a
larger number of samples continue to show that gold is easily
recoverable at Tijirit" said François Auclair, Algold's President
and Chief Executive Officer. "These strong results, indicating 99%
recovery along with the ongoing programs, should enable Algold to
expand the metallurgical work, focusing on the process and recovery
optimization in 2018, further advancing the Tijirit project".

Quality
Assurance / Quality Control (QA/QC)
Analytical work was carried pout at SGS Lakefield.
an ISO/IEC 17025 Certified Laboratory.
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
g 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 g 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 g fire assay with
gravimetric finish. Selected samples may be re-analyzed using
a 1 kg cyanide leach (Bottle Roll) using "LeachWELL" or the 1 kg
screen fire assay method. Blanks, duplicates and certified
reference material (standards) are inserted to monitor laboratory
performance during the analysis.
