Viva Gold Corp. (VAUCF)

Viva Gold Corp. is a junior gold company whose entire strategic focus is the Tonopah Gold Project, a large, undeveloped gold deposit located in western Nevada near the town of Tonopah. The company trades on the TSX Venture Exchange (VAU) and over-the-counter in the United States (VAUCF), and is based in Canada. Viva Gold owns 100% of the Tonopah property, which covers approximately 8,800 acres of exploration and development ground in a region known as the Walker Lane—a prolific gold district that has produced several major discoveries and operating mines. The Tonopah deposit is not yet in production; Viva Gold’s task is to explore it, define its ore reserves, secure the necessary environmental and operational permits, and ultimately advance it toward mine development. The company completed a Preliminary Economic Assessment of the project that indicated potential for an open-pit, heap-leach gold operation, suggesting the deposit could be economic to develop at reasonable gold prices.

Viva Gold represents a particular niche in the mining industry: the single-asset junior company. Unlike larger mining companies with portfolios of projects spread across multiple geographies and at various development stages, Viva Gold has bet its entire value proposition on one deposit and its ability to advance it. This concentration creates both opportunity and risk. The opportunity is focus: all of the company’s capital and management effort goes toward one project, increasing the odds of successful execution. The risk is that if Tonopah encounters permitting delays, ore grade or tonnage falls short of early estimates, or market conditions change, there is no other project to fall back on.

The Tonopah deposit and the Walker Lane

The Tonopah Gold Project sits on the Walker Lane, a major structural feature in Nevada and California known for its prolific mineralization. The Lane is home to several operating gold mines, including Kinross Gold’s Round Mountain mine and other significant producers. Tonopah itself is a historic town with deep roots in Nevada mining—silver was discovered there in the 1800s, and the town boomed as a mining center before eventually declining as mines exhausted their reserves or became uneconomical. Modern exploration in the Tonopah district has identified a large low-grade gold deposit that earlier generations of miners did not exploit, either because gold prices were too low at the time or because the technology to mine it efficiently did not exist.

Viva Gold’s Tonopah deposit is described as large—meaning substantial total ounces of gold—and low-grade, meaning the gold is spread through large volumes of rock rather than concentrated in small, rich zones. This profile favors a bulk open-pit mining operation with heap leaching, a processing method that dissolves gold from low-grade ore and concentrates it for recovery. Open-pit, heap-leach operations have large upfront capital requirements to build the pit and construct the heap-leach pads, but they can process ore at low cost per ton if the volume is sufficient. Viva Gold’s Preliminary Economic Assessment (completed in June 2025) modeled the project as viable under reasonable gold price assumptions, though the outcome depends on ore tonnage estimates proving accurate and capital costs not escalating significantly.

Exploration and resource definition

Viva Gold’s principal activity is drilling to define the extent and grade of the gold deposit. Mineral deposits are defined by drilling holes at strategic locations to intersect mineralized rock, measuring the grade (gold content per ton of rock) and calculating the tonnage of ore that exceeds an economic threshold. In early-stage exploration, holes are spaced widely and may miss mineralization entirely. As a project advances toward development, the company drills infill holes to narrow the spacing and reduce the uncertainty in resource estimates. Viva Gold recently commenced a reverse-circulation drilling program at Tonopah with a planned 2,500 meters of new drilling, focused on converting “inferred” resource (the most uncertain category) to “indicated” resource (more confident) and on expanding the resource in areas not yet fully drilled.

This process can take years. Each drill campaign requires planning, permitting at the local level, mobilizing rigs, drilling, analyzing results, and then planning the next round of drilling. As the company drills, it is also building the geological model—understanding the controls on mineralization, identifying the boundaries of the ore body, and identifying extensions where mineralization might continue beyond what is currently known. The quality of resource estimates improves as drilling density increases, but at a cost: every drill hole costs money. A company with limited capital must balance the desire for more certainty with the need to preserve cash. The risk for Viva Gold is that as it drills, results could prove disappointing—the deposit could be smaller, lower-grade, or more structurally complex than early indications suggested, reducing its economic viability.

The path from exploration to permitting to production

If Viva Gold’s drilling confirms a sufficiently large, high-grade deposit, the next phase is feasibility study—a detailed engineering and economic assessment that forms the basis for permitting applications. The company would hire engineering firms and mining consultants to produce a comprehensive mine plan, estimate capital costs, project operating costs, and model net present value under various gold price scenarios. This study typically takes a year or more and costs millions of dollars.

Parallel to the feasibility study comes permitting. Nevada has a established permitting framework for mining, but the process remains complex and lengthy. The company must prepare environmental assessments, demonstrate water availability and management, address tribal consultation requirements, and obtain permits from multiple state and federal agencies. Permitting can take two to five years or longer, and there is risk of delays, challenges, or requirements for additional studies. Environmental permitting for mining has become increasingly contentious nationwide, and a project in Nevada, while in a relatively mining-friendly jurisdiction, could still face opposition from environmental groups or local communities.

If permitting succeeds and the project is approved, the company must then raise capital for mine development—potentially hundreds of millions of dollars depending on the mine’s scale. This could come from debt financing, joint venture with a larger mining company, or a combination of both. It is at this stage that Viva Gold’s single-asset structure becomes a challenge: the company does not have the balance sheet to fund a major mine development on its own. It would need to partner with or be acquired by a larger company, effectively selling its ownership stake in the deposit to fund development.

Commodity price and funding risk

Viva Gold’s economic case for Tonopah is built on gold prices. The Preliminary Economic Assessment modeled the project at various gold price assumptions. If gold prices rise significantly above those assumptions, the project becomes far more valuable and easier to finance. If gold prices fall sharply, the project could become uneconomic, and the company’s value could collapse accordingly. This commodity price risk is endemic to gold exploration companies and is not unique to Viva Gold, but it is critical to understand: shareholders in Viva Gold are effectively taking a long position on gold prices.

The second risk is funding. Viva Gold needs capital to fund exploration and feasibility work for years before the project could generate revenue. If gold prices fall and discourage investment in new projects, if permitting delays require additional studies, or if early drilling results are disappointing, the company may struggle to raise capital. A junior explorer that runs out of cash before a project reaches value-inflecting milestones (such as a positive feasibility study or a major resource upgrade) is forced into distressed financing or sale at unfavorable terms. Monitoring Viva Gold’s quarterly cash position and burn rate is essential for understanding how long the company can operate at its current pace before needing to raise new capital.

How to research Viva Gold as an investment

Begin with the Preliminary Economic Assessment, which Viva Gold has published, to understand the modeling assumptions—gold price, ore tonnage, ore grade, capital costs, operating costs, and resulting net present value. Note any sensitivities in the model to gold price changes; this reveals how much of the project’s value is dependent on gold prices. Review the company’s recent drill results in press releases: are intercepts trending toward larger grades and widths, or smaller? Are results from infill drilling confirming earlier grades, or revising them downward? Read the quarterly financial statements to monitor cash burn and remaining working capital. Watch for announcements regarding permitting progress, milestones, or agency decisions. Monitor gold prices as a leading indicator of project risk—a sustained decline in gold prices increases the risk that the project becomes uneconomic. Finally, keep an eye on whether the company announces any partnership discussions with larger mining companies, which would indicate progress toward de-risking the project and funding its development. This is a speculative investment on exploration success, permitting, and commodity prices—all of which are inherently uncertain.
