Alexandria Minerals Corporation (TSX-V:AZX) (OTCQB:ALXDF)
(Frankfurt:A9D) (“
Alexandria” or the
“
Company”) is pleased to announce that the newly
completed mineral resource estimate at Orenada comprises 3,754,000
tonnes of indicated mineral resources with an average grade of 1.61
grams of gold per tonne (“
g/t Au”) for 194,522
ounces of contained gold and 2,079,000 tonnes of inferred mineral
resources with an average grade of 1.89 g/t Au for 126,259 ounces
of contained gold.
Highlights
- Orenada Zone 4: Updated indicated
mineral resource of approximately 3.75 million tonnes with an
average grade of 1.61 g/t Au for 194,522 oz of contained gold and
an updated inferred mineral resource of 1.19 million tonnes with an
average grade of 1.92 g/t Au for 73,710 oz of contained
gold
- Orenada Zone 2 and 4: Updated total inferred mineral
resource of 2.08 million tonnes with an average grade of 1.89 g/t
Au for 126,259 contained ounces
- The updated resource was modelled using detailed
geological wire frames of mineralized structures and consisted of
both an open pit (0.4 g/t Au cut-off) and underground mining
scenario (2.0 g/t Au cut-off)
- There is potential to extend the resource towards
the western extension of the Orenada resource. The
updated resource report will be thoroughly evaluated within the
context of the additional 6,500 un-assayed samples and historical
results that the Company has in its possession before any future
drilling decisions are made

Mineral Resource Estimate Notes:
- Each of Alain Carrier, P.Geo., M.Sc. and Claude Savard, P.Geo.
(InnovExplo) is a “qualified person” (as defined by NI 43-101), and
both are considered to be “independent” of the Company for purposes
of section 1.5 of NI 43-101. InnovExplo is also considered to be
“independent” of the Company for purposes of section 1.5 of NI
43-101. The effective date of this mineral resource estimate is May
25, 2018.
- These mineral resources are not mineral reserves, as they do
not have demonstrated economic viability.
- Resources are presented undiluted and in situ for both open pit
and underground potential scenarios and are considered to have
reasonable prospects for economic extraction.
- The estimate encompasses two different zones (Orenada Zone 2
and Orenada Zone 4) subdivided into mineralized sub-domains (i.e.
V1, and V2 mineralized sub-domains) each defined by individual
wireframes with a minimum true thickness of 2 metres included
within a broader domain (or dilution envelope).
- High-grade capping was done on raw assay data before
compositing and established on a per zone basis: V1 domains of
Zones 2 and 4 at 20 g/t Au, V2 domains of Zone 4 at 35 g/t Au, and
broader domain (or dilution envelope) at 9 g/t Au.
- Bulk Density values were applied on the following lithological
basis (g/cm3): Zone 4 = 2.87; Zone 2 = 2.84, mafic and ultramafic =
2.87.
- Grade model resource estimation was evaluated from drill hole
data using an Ordinary Kriging interpolation method on a block
model using a block size of 5 x 5 x 5 metres.
- The estimate is reported at a 0.4 g/t Au cut-off for
the open pit potential and at a 2.0 g/t Au cut-off for the
underground potential. The cut-off grades were calculated using a
gold price of USD1,300/oz, CAD:USD exchange rate of 1.29 (1-year
trailing average) and the following parameters: (a) Open pit
scenario: mining cost per tonne = CAD 3.50; processing cost = CAD
15.00; G&A = CAD 4.00, pit slope of 50 degrees used during
Whittle optimization, (b) Underground scenario: mining cost = CAD
75.00; processing cost = CAD 15.00; G&A = CAD 8.00. The cut-off
grades should be re-evaluated in light of future prevailing market
conditions (metal prices, exchange rate, mining cost, etc.)
- The mineral resource estimate presented herein is categorized
into indicated and inferred mineral resources. Indicated were
limited to the Zone 4 area and where the drill spacing corresponds
to 25 to 30 metre spacing. The inferred category was used for Zone
2 and for remaining areas of Zone 4 where drill spacing is less
than 80 to 100 metres and shows reasonable geological and grade
continuity.
- The mineral resource estimate was prepared using GEOVIA GEMS
6.8. The estimate is based on 529 diamond drill holes. A minimum
true thickness of 2.0 metres was applied, using the grade of the
adjacent material when assayed, or a value of zero when not
assayed.
- Calculations used metric units (metres, tonnes, gram per
tonne). Metal contents are presented in troy ounces (tonne x grade
/ 31.10348).
- The number of metric tons was rounded to the nearest thousand.
Any discrepancies in the totals are due to rounding errors.
- CIM definitions and guidelines for mineral resources have been
followed.
- InnovExplo is not aware of any known environmental, permitting,
legal, title-related, taxation, socio-political or marketing
issues, or any other relevant issue not reported in the Technical
Report that could materially affect the mineral resource
estimate.
Orenada Resource EstimateThe updated mineral
resource estimate at Orenada incorporated 40,954 assay results from
samples falling within the different mineralized domains, obtained
from 529 diamond drill holes (392 surface drill holes and 137
underground drill holes) variably spaced from 25 to 100 metres
apart and totalling nearly 100,500 metres. The drill hole database
comprises both historic holes and 131 new drill holes (36,000
metres) completed in 2016 and 2017. Only drill assays received
prior to December 15, 2017 are included in the resource estimate.
The resource estimate is also based on a new interpretation of the
gold-bearing structural zones and a better geological understanding
of Orenada Zone 4.
The recent drilling has enlarged the foot print
and better defined the high-grade vein system in Zone 4 and
extended the mineralized veins to a strike length of 1,100
metres.
The estimate was prepared using a block model
constrained within 3D wireframes (domains and narrow wireframes)
for the Zone 4 and Zone 2 mineralized areas constructed by
InnovExplo Inc. Values for gold were interpolated into blocks using
a 3-pass Ordinary Kriging (OK) interpolation method using a 5 x 5 x
5 metre block size. This mineral resource estimate incorporates
mining assumptions relating to both an open pit (0.40 g/t Au
cut-off) and an underground mining extraction method (2.0 g/t Au
cut-off) to support the CIM requirement that Mineral Resources have
'reasonable prospects for eventual economic extraction'. The
effective date of this resource estimate is May 25, 2018.
Exploration PotentialAt this stage, it is
reasonable to believe that somewhere between 1.5 and 2.0 million
tonnes of ore at grades between 1.5 and 2.0 g/t Au may be added by
drilling the extensions of currently defined mineralized zones.
This exploration target is not a mineral resource estimate and is
conceptual in nature. There has been insufficient exploration to
define this as a mineral resource, and it is uncertain if further
exploration will result in the exploration target being designated
as a mineral resource.
The basis for the 1.5 to 2 million tonnes with
an average grade of 1.5 to 2.0 g/t Au for the exploration target
includes the following:
- Two significant mineralized zones (Zones 2 and 4) have been
identified on the property and are the subject of the current
mineral resource estimate. Collectively, these two zones are open
at depth and have a sufficient footprint to potentially host
additional mineralization.
- Drilling results from six drill holes located west of Zone 4
and in the range of 300 to 400 metres from surface potentially
indicates the occurrence of a third mineralized trend.
- It is assumed that these third mineralized zones will have
similar width and continuity in their Western extensions. This is
supported by the fact that the bulk of the current mineral resource
estimate is within the first 250 vertical metres with some drill
holes encountering mineralization down to a vertical depth of 400
metres.
- Drilling the gaps between some of the zones is also considered
in this assumption.
- The grade range is considered reasonable based on the current
mineral resource estimate.
Orenada Resource DiscussionThe
2018 resource update at Orenada Zones 4 and 2 has resulted in a
much more robust resource compared to the historical 2009 resource
estimate. The new resource was constrained within geological wire
frames constructed by InnovExplo of the logged mineralized
structures. The open pit portion was constrained to a simulated
Whittle open pit run and utilized a 0.40 g/t Au cut-off.
Underground resources beneath the open pit were constrained to
those above a 2.00 g/t Au cut-off. The 2009 resource
(prepared in accordance requirements at the time), was not
geologically constrained nor was it open pit constrained. The
resource was constrained to a vertical depth of 250 metres with no
pit constraints.
Between 2009 and 2018, published and internal
resource estimates were developed using different assumptions.
These have changed the resource with the biggest effect coming from
the pit shell constraint on the resource model as required under
the updated 43-101 requirements. This has resulted in a large
portion of the old resource occurring outside of the Whittle pit
shell and below the underground cut-off grade of 2g/t Au in
isolated blocks which under the new updated 43-101 regulations are
not able to be included in any resource category. For comparison
permits the historical 2009 resource at a similar grade is included
in table 2.

which are not mineral reserves do not have economic viability. |
|
|
|
3. Measured and
indicated mineral resources are reported to a depth of 250 meters
and at a cut off grade of 1.0 g/t Au. Inferred mineral resources
are related to a depth of 250 meters at a cut off grade of 1.0 g/t
Au. |
|
|
|
4. Historical
production of 20,418 tonnes at 0.054 oz/t Au was mined from a small
open pit at the surface of Zone 4. Gold recovery of 78.5% was
obtained. In 1994, Aur Resources has milled 72,195 tonnes at 1.72
g/t Au on Zone 4. These productions were subtracted from indicated
and measured resources. |
Next StepsThe updated resource
estimate at Orenada utilized only those assays received up to
December 15, 2017. Another 10,500 metres of drilling in 37 holes
has not been included in the resource at Orenada covering the Zone
2 and West-Extension areas. A new interpretation and modelling of
the additional zones of mineralization intercepted in the West
Extension areas and Zone 2 of Orenada will be used to direct future
drilling.
Analytical Procedures and
QA/QC Each of Alain Carrier,
P.Geo., M.Sc. and Claude Savard, P.Geo. (InnovExplo) is a
“qualified person” (as defined by NI 43-101), and both are
considered to be “independent” of the Company for purposes of
section 1.5 of NI 43-101. InnovExplo is also considered to be
“independent” of the Company for purposes of section 1.5 of NI
43-101.
Quality Control/Quality Assurance (QA/QC) is
conducted by Alexandria’s exploration group under the supervision
of Philippe Berthelot, P. Geo, who is a “qualified person” employed
by the Company. Mr. Berthelot has reviewed and approved the
contents of this press release.
Drill core sampling protocol is conducted
according to industry standards, and has been reviewed by the
Company’s independent Qualified Person. Half-core samples are
shipped to AGAT, Bureau Veritas Minerals, or SGS Canada
laboratories for assaying. For visibly mineralized core, the entire
core sample is crushed to 75% passing -2mm (10 mesh); a split of 1
kg of crushed material is then pulverized to more than 85% passing
75 microns (200 mesh). Two pulp samples, 50 g each, are analyzed by
Fire Assay (FA) with an Atomic Absorption Spectrometry (AAS)
finish. Samples assaying >10.0 g/t Au are re-analyzed with a
gravimetric finish on two 50 g charges for each sample.
For core samples located between mineralized
intersections, the core is crushed to 75% passing -2 mm (10 mesh).
A 250 g split of this material is pulverized with 85% passing 75
microns (200 mesh); one pulp sample (50 g) is analyzed by Fire
Assay (FA) with an Atomic Absorption Spectrometry (AAS) finish.
Commercial certified standard materials and
blanks are systematically inserted by Alexandria’s geologists into
the sample chain after every 17 core samples as part of the QA/QC
program. Duplicate samples are systematically analyzed by the
laboratories after every 17 core samples. Third party assays are
submitted to other designated laboratories for 5% of all
samples.
