Velocity Minerals Ltd. (TSXV: VLC) (“
Velocity” or
the “
Company”) reports that it has filed an
updated National Instrument 43-101 Standards of Disclosure for
Mineral Projects (“
NI 43-101”) technical report
for the Durusu deposit at the Obichnik gold project
(“
Obichnik” or
the “
Project”), southeast Bulgaria (the
“
Updated Technical Report”). The Updated Technical
Report incorporates an updated Inferred Mineral Resource estimate
for the Project, and incorporates the results of recently completed
metallurgical test-work, which indicates leach recoveries of
approximately 95% for combined oxide and transitional material, and
96% for fresh / sulphide material.
The Updated Technical Report entitled “NI 43-101
Technical Report Exploration and Mineral Resource Estimation for
the Obichnik Property, Republic of Bulgaria” is dated December 8,
2021 and has an effective date of December 6, 2021, and was
prepared by Jonathon Abbott, BASc, MAIG. The Updated Technical
Report is available on the Company’s SEDAR profile at www.sedar.com
and on the Company’s website at www.velocityminerals.com.
The Updated Technical Report updates and
replaces the previous technical report for the Project dated March
20, 2021 (the “March 2021 Report”).
Resource Estimate Methodology and
Assumptions
Recoverable resources were estimated for the
Durusu Zone at Obichnik using Multiple Indicator Kriging (“MIK”)
with block support adjustment, a method that has been demonstrated
to provide reliable estimates of recoverable open pit resources in
gold deposits of diverse geological styles. The resource estimates
include a variance adjustment to give estimates of recoverable
resources above gold cut off grades for selective mining unit
(“SMU”) dimensions of 5m east by 2m north by 2m in elevation. The
variance adjustments were applied using the direct log-normal
method.
The estimates are based on data from diamond
drilling undertaken by Velocity since 2019 and includes drilling
information available on the 10th of February 2021 comprising 37
holes for 6,820m. Velocity’s diamond holes are inclined to the
southwest at generally 50o at generally around 25m spacing along
generally 50 m spaced traverses with rare closer spaced holes.
Resource modelling incorporated two steeply
northwest dipping mineralized domains interpreted from 2m down-hole
composited gold grades and capturing intervals of greater than 0.1
g/t (Figure 1, Figure 2). The main, northern domain extends over
approximately 380m of strike with an average width of around 80m.
The subsidiary southern domain averages around 40m wide over 320m
of strike. Mineralization is characterized as structurally
controlled steep epithermal replacement of the volcanic host with a
large envelope of alteration that forms part of a 2.5km by 1km wide
intrusive related hydrothermal mineralizing system.
Model blocks are categorized by oxidation zone
from triangulated surfaces representing the base of complete
oxidation and top of fresh rock interpreted from geological logging
of Velocity’s diamond holes. Within the resource area the depth to
the base of complete oxidation averages around 55m, with fresh rock
occurring at an average depth of around 68m.
Bulk densities of 2.30, 2.50 and 2.55 tonnes per
cubic metre were assigned to completely oxidized, transitional and
fresh material respectively on the basis of 30 immersion density
measurements performed by Velocity on diamond drill core
samples.
All class grades were for MIK modelling
determined from bin mean grades with the exception of the upper
bins, which were reviewed on a case by case basis for each
mineralized domain/oxidation zone subset and bin grades selected on
the basis of bin mean, or median with or without exclusion of high
grade composites. This approach was adopted to reduce the impact of
a small number of outlier composites.
Table 1 show the Inferred Mineral Resource
estimates for Durusu and Table 2 shows the estimates by oxidation
zone. The figures in these tables are rounded to reflect the
precision of the estimates and include rounding errors.
The Updated Technical Report reports Mineral
Resources within an optimized pit shell generated with the
parameters shown in Table 3. These parameters were derived from
recent metallurgical test-work performed on samples of Durusu
mineralization as described below and the parameters used for
generating the pit shell constraining Mineral Resource estimates
for Velocity’s Rozino deposit, for which evaluation is more
advanced than Durusu. The gold price of $US 1,500/oz was
selected from the trailing five-year average gold price with
appropriate rounding. These parameters generate a gold cut-off
grade of 0.3 g/t for oxide, transitional and fresh mineralization
and this cut-off was selected for Mineral Resource
reporting.

The Updated Technical Report differs from the

reported from the February 2021 block model constrained within an
optimal pit shell rather than being truncated at 180 m depth.

Metallurgical Testing
In August 2021 two composite samples of
jaw-crushed coarse reject samples of Velocity diamond core were
submitted to Eurotest Control EAD in Sofia (“Eurotest”) for
metallurgical test-work. These samples were selected as
representing combined oxidised and transitional and fresh
mineralization respectively as follows.
- Combined oxide and
transition sample: ОМ-ОТ-01 was produced from 481 sample intervals
comprising 391 and 90 samples from intervals geologically logged as
oxidised and transition respectively.
- Fresh sample:
ОМ-F-02 was produced from 343 sample intervals geologically logged
as fresh.
The combination of oxidised and transitional
material into a single sample for metallurgical test-work reflects
the small proportion of Mineral Resources hosted by transitional
material and the expected metallurgical similarity of the two
material types.
Eurotest, Sofia, unified and homogenized each of
the samples by hand-mixing for 30 minutes, followed by passing
twice each through a riffle splitter and rotary splitter, with
final splitting of homogenized sample into 1 Kg portions. The
samples were subjected to test-work comprising complete chemical
and mineralogical characterization, phase analysis (Diagnostic
Leach Test) of gold present in each sample and testing to determine
cyanide leaching kinetics and degree of gold recovery.
Gold head grades were determined for each sample
from the average of four fire assays. The test results, including
agitated cyanide leaching under the conditions shown in Table
4 demonstrate that mineralization represented by the two
composite samples is amenable to standard Carbon in Leach (CIL)
processing, with estimated gold recoveries of around 95% and 96%
for the oxide/transition and fresh samples respectively. The
test-work does not indicate any processing factors or deleterious
elements that could have a significant effect on potential economic
extraction.
Metallurgical test work for Obichnik
mineralization available in March 2021 and described in the March
2021 Report comprised preliminary metallurgical tests performed by
Geoengineering summarised in a 2010 Commercial Discovery report.
Details of this older test-work, which gave gold recoveries of
80.6% to 97.6% from floatation tests and 81.3% from cyanide leach
tests respectively are unknown. The Updated Technical Report
describes the 2021 Eurotest metallurgical test work and summarises
the older test-work. The author of the Updated Technical Report
regards the 2021 Eurotest analyses as a more reliable indication of
potential metallurgical recoveries for processing of Durusu
mineralization than the older results.

Quality Assurance / Quality Control /
Laboratory Independence
The exploration and drilling program at Obichnik
was designed and supervised by Stuart A. Mills, CGeol, the
Company's Director of Geology, who was responsible for all aspects
of the work, including the quality control/quality assurance
program. On-site personnel at the project rigorously collect and
track samples which are then security sealed and shipped to ALS
Global laboratory in Romania. Samples were prepared and analyzed by
fire assay using a 30-gram charge in compliance with industry
standards. Field duplicate samples, blanks and independent
controlled reference material (standards) are included in every
batch. An additional sample taken from each pulverized sample is
shipped to ALS Global laboratory in Ireland for aqua regia digest
and silver plus multi-element analysis by Inductively Coupled Mass
Spectrometry (ICPMS).
The sampling and metallurgical test-work was
supervised by Daniel Marinov MAIG RPGeo, who is responsible for all
aspects of the work, including the quality control/quality
assurance program. Eurotest’s operations have been accredited as
compliant with ISO 9001:2015.
ALS Global and Eurotest are independent of
Velocity and provided analytical services on a standard commercial
