PRELIMINARY METALLURGICAL ASSESSMENT
BAM EAST GOLD PROSPECT
JUNIOR LAKE PROPERTY
London, United Kingdom - January 23rd 2017 - Landore Resources
Limited (AIM:LND) ("Landore Resources" or "the Company") is pleased
to provide results of the Preliminary Metallurgical Assessment of
the BAM East Gold prospect mineralization on its Junior Lake
Property, Ontario, Canada ("BAM East Gold Prospect").
Preliminary Assessment of Metallurgical Composites from the BAM
East Gold Prospect: Drill core material, in the form of two
composites of 28 samples weighing a total of 67 kilograms, was
submitted to ALS Metallurgy, Kamloops of British Columbia for
Gravity Concentration and Cyanidation Bottle Roll leach testing on
the gravity tails.
Highlights:
-- Combined gold recovery by gravity concentration followed by
cyanidation leach extraction of the gravity tail averaged about 98
percent for both composites tested.
-- Gravity Concentration: Feed gold recovery to the pan
concentrate ranged between 58 and 59 percent for Composite 1 and
Composite 2. Between 0.02 and 0.03 percent of the feed mass was
recovered to the pan concentrates grading between 3,687 and 6,977
grams/tonne gold.
-- Gold leach kinetics recorded for all tests at a nominal
primary grind sizing of 75um K(80) were rapid, with close to peak
gold extraction measured in the first sampling interval at 6
hours.
Commenting on this report, Chief Executive Officer of Landore
Resources, Bill Humphries, said:
"These outstanding results, showing 98% recovery of gold using a
simple combined gravity/leaching process, further supports our
expectations that the exciting BAM East Gold deposit has the strong
potential of low capex/opex costs amongst the lowest quartile of
gold mining producers.
Metallurgical Testing:
The preliminary assessment was designed to assess the
metallurgical response of the mineralised samples from the BAM East
Gold deposit and to provide a determination of the gold feed grade.
The two composites were assessed for the following:
-- Chemical characteristics of the feed.
-- Potential for gravity recovery of gold from Composite 1 and Composite 2.
-- Cyanidation leach response of the gravity tails for the two composites.
The two representative composites were selected using crushed
half drill core from two previously reported intersections within
the Central Zone consisting of:
Composite 1: Line 2600E, Drill-hole 0416-525 (NQ diamond core)
from 65 metres depth, intersection reporting 1.90grams/tonne (g/t)
gold over 9.0m. There was no recorded visible gold (VG) and the
highest grade was 6.38g/t over one metre.
Total weight of Composite 1 was approximately 15 kilograms.
Composite 2: Line 2400E, Drill-hole 0416-547 (HQ diamond core)
from 217.25 metres depth, intersection reporting 2.32g/t gold over
16.68 metres. There were 6 recorded sightings of VG and the highest
grade was 17.35g/t over one metre.
Total weight of Composite 2 was approximately 52 Kilograms.

Extract from Final report:
Conclusions and Recommendations:
Metallurgical testing with Composite 1 and Composite 2 was
performed at a nominal primary grind sizing of 75um K(80) . The
entire mass remaining of each Composite, about 12 kilograms for
Composite 1 and 45 kilograms for Composite 2, were introduced to
the Knelson concentrator.
Gravity separation test work results indicated that the two
composites were amenable to gravity separation. Gold recovery by
Knelson gravity separation followed by hand panning of the Knelson
concentrates ranged between 58 and 59 percent free gold. High grade
pan concentrates grading 3,687 and 6,977 g/tonne gold were measured
for Composite 1 and Composite 2, respectively.
Between 98 and 99 percent of the free gold was recovered through
combined gravity concentration and cyanidation leaching of gravity
tails for the two composites tested. Gold leach kinetics were fast,
with most of the gold extraction taking place within the first six
hours. Sodium cyanide and lime consumption averaged about 0.1 and
0.3 kg/tonne, respectively. Gold head grades were calculated at 2.0
g/tonne for both composites based on the combined gravity and
cyanidation leach test results.
Further gravity and cyanidation leach testing at coarser primary
grind sizing is recommended to determine whether similar gold
recovery can be achieved with lower comminution energy
requirements. Further testing of other zones within the deposit is
also recommended.
