looking information”), including but not limited to forwar d-looking information related to Mineral

Resource estimates for the Project. The material factors that could cause actual results to differ materially

from the conclusions, estimates, designs, forecasts or projections in the forward -looking information

include any significant differences from one or more of the material factors or assumptions that were set

forth in this press release including geological and grade interpretations and controls and assumptions

and forecasts associated with establishing the prospects for economic extraction of gold mineral resource

and preliminary economic analysis at the Tonopah Gold Project. This forward-looking information entails

various risks and uncertainties that are based on current expectations, and actual results may differ

materially from those contained in such information. These uncertainties and risks include, but are not

limited to, the strength of the global economy, inflationary pressures, pandemics, and issues and delays

related to permitting activities; the price of gold; operational, funding and liquidity risks; the potential for

achieving targeted drill results, the degree to which mineral resource estimates are reflective of actual

mineral resources; the degree to which factors which would make a mineral de posit commercially viable

are present; the accuracy of capital and operating cost estimates; the variability of actual from estimated

gold recovery; potential for geotechnical issues; the risks and hazards associated with drilling and mining

operations; an d the ability of Viva to fund its capital requirements. Risks and uncertainties about the

Cautionary Note to Investors --- Investors are cautioned not to assume that any "measured mineral

resources", "indicated mineral resources", or "inferred mineral resources" that the Company reports in

this news release are or will be economically or legally mineable. United States investors are cautioned

that while the SEC now recognizes "measured mineral resources", "indicated mineral resources" and

"inferred mineral resources", investors should not assume that any part or all of the mineral deposits in

these categories will ever be converted into a higher category of mineral resources or into mineral

reserves. These terms have a great amount of uncertainty as to their economic and legal feasibility. Under

Canadian regulations, estimates of inferred mineral resources may not form the basis of feasibility or pre-

feasibility studies, except in limited circumstances. Further, "inferred mineral resources" have a great

amount of uncertainty as to their existence and as to their economic and legal feasibility. It cannot be

assumed that any part or all of an inferred mineral resource will ever be upgraded to a higher category.

The mineral reserve and mineral resource data set out in this news release are estimates, and no assurance

can be given that the anticipated tonnages and grades will be achieved or that the indicated level of

recovery will be realized.

Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies

of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.

Definitions

“All-in sustaining costs” is a non -IFRS or US GAAP financial measure calculated based on guidance

published by the World Gold Council (“WGC”). The WGC is a market development organization for the

gold industry and is an association whose membership comprises leading gold mining companies. Although

the WGC is not a mining industry regulatory organization, it worked closely with its member companies to

develop these metrics. Adoption of the all -in sustaining cost metric is voluntary and not necessarily

standard, and therefore, this measure presented by the Company may not be comparable to similar

measures presented by other issuers. The Company believes that the all -in sustaining cost measure

complements existing measures and ratios reported by the Company. Al l-in sustaining cost includes both

operating and capital costs required to sustain gold production on an ongoing basis. Sustaining operating

costs represent expenditures expected to be incurred at the Project that are considered necessary to

maintain produ ction. Sustaining capital represents expected capital expenditures comprising mine

development costs, including capitalized waste, and ongoing replacement of mine equipment and other

capital facilities, and does not include expected capital expenditures for major growth projects or

enhancement capital for significant infrastructure improvements.

“Cash cost per gold ounce” is a common financial performance measure in the gold mining industry but

has no standard meaning under IFRS or US GAAP. The Company believes that, in addition to conventional

measures prepared in accordance with IFRS or US GAAP, certain investors use this information to evaluate

the Company’s performance and ability to generate cash flow. Cash cost figures are calculated in

accordance with a standard developed by The Gold Institute. The Gold Institute ceased operations in 2002,

but the standard is considered the accepted standard of reporting cash cost of production in North America.

Adoption of the standard is voluntary, and the cost measures presented may not be comparable to other

similarly titled measures of other companies.
