Victory Metals Demonstrates Over 90% Vanadium Recovery Using a

Hydrometallurgical Leach Process at the Iron Point Project, Nevada

VANCOUVER

/CNW/ -

Victory Metals

("

TSX-V:VMX

") ("

Victory

" or the "

Company

") is pleased to announce results from initial metallurgical tests

conducted by McClelland Laboratories, Inc. ("

McClelland Laboratories

") of

Sparks, Nevada

, on drill cuttings from the Company's Iron Point Vanadium Project.

Test work using hydrometallurgical processes at atmospheric pressure has yielded vanadium recoveries in excess of 90% in leach times of less than eight hours.

Highlights – Phase I Metallurgical Testwork

Initial bench-scale hydrometallurgical leach testing on Iron Point RC drill cuttings demonstrate up to 94.3% vanadium recovery at atmospheric pressure and 8-

hour leach times

RC drill cutting Master Composite used in testing had a median head grade of 0.38% V

16 preliminary tests were completed utilizing the Master Composite and varying four test factors: temperature, slurry solids density, and concentrations of

hydrofluoric and sulphuric acid

Phase II testing is underway that will further define operating parameters required to develop an economic atmospheric leaching process for Iron Point

vanadium mineralization

Jeff Woods

, Victory's Chief Metallurgist stated: "Preliminary testing last year by McClelland Laboratories on drill core samples indicated that a low-cost

atmospheric leach may be suitable for Iron Point vanadium mineralization. A review of published work led to the first phase of experimental tests released today

utilizing RC drill cuttings. Our preliminary tests confirm that an atmospheric leach process can successfully recover vanadium at levels greater than 90% with

potential for relatively low acid consumption. We are in the process of augmenting the initial test work to optimize recovery and minimize operating costs, before

starting variability testing and solvent extraction/precipitation testing."

Paul Matysek

, Executive Chairman, stated: "Initial metallurgical testing conducted at McClelland Laboratories is very encouraging, creating a pathway forward to

a potentially economic processing route for the Iron Point Vanadium Project. Importantly, the methods explored are done at ambient pressure without the use of

costly pressure oxidization or roasting. Furthermore, these hydrometallurgical methods are commonly utilized in base metal processes and show promise for

applicability to vanadium recovery. Our maiden drilling campaign clearly outlined a large mineralized system. With promising initial metallurgical results returned to

date, we can work towards identifying an economic process that will allow us to fast track towards resource definition and a Preliminary Economic Assessment."

Phase I Testwork

A total of 197 Reverse Circulation ("

RC

") drill reject samples were delivered to McClelland Laboratories of

Sparks, Nevada

, for sample prep, assaying, and

compositing. McClelland Laboratories, established in 1986, is recognized as a top mineral-processing laboratory with a focus on hydrometallurgical extraction of

precious and base metals, as well as specific experience in vanadium metallurgy. Their experience and knowledge have accelerated the development of Victory's

atmospheric hydrometallurgical process.

A Master Composite sample was constructed using 197 drill cuttings interval samples that best represented both the spatial and stratigraphic distribution of

mineralized zones throughout the Iron Point Project as described in Table 1 and shown in Figure 1. Specifically, the Master Composite is made up of cuttings from

drill intervals ranging between a depth of

1.5 m

to

164.6 m

. Intervals incorporated into the composite had a minimum grade of 0.17% V

After a review of published work and some early test work on drill core samples, a Design of Experiments program (DOE) was initiated as a scoping level trial

using four primary leaching factors, namely: leach temperature, slurry solids density, hydrofluoric acid dosage and sulfuric acid dosage. DOE methods are used to

determine the effects of several factors at once and are statistically analyzed to determine the effects of each factors, i.e. acid dosage or temperature, also the

interaction of two or more factors on the system, i.e. temperature and slurry solids density. Owing to the number of factors, a two-level factorial design was used

for the initial runs. Sixteen tests were run using different combinations of Hi and Lo values for each of the factors. All tests were run at atmospheric pressure with

a leach time of eight hours. Initial factor high and low levels were selected based on similar unit operations currently used in the industry, i.e. slurry solids density

20 to 50 percent, which is common in flotation concentrate products and gold leach circuits, respectively. Owing to the atmospheric leaching process, maximum

temperature considered was 100 degrees centigrade. Intermittent samples were taken at two, four, and six hours and each solution analyzed for pH, oxidation-

reduction potential (ORP), and acid concentration. For each test make-up, water and reagents were added as required to maintain the DOE factor levels. At the

termination of the test, samples were filtered with dried solids and leach solutions submitted for analyses. Statistical analysis of the data was done using Stat-

Ease's Design Expert and SAS' JMP statistical analysis software.

Conditions for DOE-8 are being re-run owing to anomalies with the acid balance results.

Table 2 shows the high and low level for each of the tests, as well as two of the primary responses, namely vanadium recovery percentage and sulfuric acid

consumption. Highlighted areas correspond to the upper quartile of vanadium recovery, i.e. the top four tests. The highest vanadium recoveries are associated

with some combination of higher sulfuric acid dosage and temperature. The best four combinations average 91.7% vanadium recovery with the highest recovery of

94.3% associated with a low percentage of solid solution, and higher temperature and acid dosage. The upper quartile vanadium tests show acid consumptions

ranging between 88 kg/t and 142 kg/t with an average of 109 kg/t.

The high temperature runs consistently outperformed the low temperature runs with respect to vanadium. Acid dosages have a lower level of impact than

temperature on recovery. High solids density has a negative influence on the recovery, though not as statistically significant as temperature or sulfuric acid

dosage.

Phase II Testing Underway

Further testing is underway that will better define operating parameters required to develop an economic atmospheric leaching process. It should be noted that

the initial DOE runs are not optimized. Supplemental testing is in progress to augment the initial DOE with additional runs to optimize the leach parameters. It is

expected that improvements in recovery and acid consumption are likely.

Testing of several samples spatially distributed throughout the deposit and at different vanadium grades, will also be completed ("variability testing") to confirm

metallurgical responses throughout the deposit. Results of the variability testing will be used to develop the geometallurgical model for the Iron Point deposit and

support the engineering and design process. Additionally, bulk samples will be used to generate pregnant leach solution for subsequent solvent extraction and

vanadium precipitation testing. Owing to the nature of the Victory leach process, downstream processing of the vanadium rich solutions will be via a commercially

proven process to produce a high grade V
