Drilling Begins at EP Gold Project in Sonora

Date:

Colibri Resources (TSXV: CBI / OTC: CRUCF) has started drilling in a new campaign at the EP Gold Project in Sonora, Mexico — which is an interesting property since it is completely surrounded by Fresnillo plc, which is among the largest producers of precious metals in Mexico. Given previous surface work showed clear evidence of gold and a geological framework consistent with the adjacent producing systems, this drilling program may be a turning point for the Company. Should EP succeed, Colibri will go from being a relatively quiet junior explorer to a near-mine discovery story.

Why This Drill Program Matters

Proximity to a Major Producer

EP is not simply a good address — it is situated in a well-established gold district, with all sides of the claim controlled by Fresnillo. This enhances the geological prospectivity dramatically when a major controls the surrounding land packages. Typically, when a major controls a large section of the land around your property, the underlying structure is considered to be valid and economic.

Under-Developed Geological Trend

While historic exploration work has provided evidence for:

  • Long gold bearing trends
  • Multiple surface gold showings
  • Several shallow drill intersections with gold

Much of the Project remains under-explored. The current drilling program is specifically focused on testing those unexplored structural extensions — and it is in those structural extensions where many of the greatest discoveries are made. Therefore, if drilling can demonstrate continuity, scale or grade at EP, it has the potential to rapidly develop into a key asset for Colibri.

Tier One Jurisdiction

Sonora is home to mines operated by Agnico Eagle, Alamos Gold, Minera Alamos, Argonaut Gold and Fresnillo. As such, Sonora is one of the most mine-friendly jurisdictions in the Western Hemisphere — with significant infrastructure, an established workforce, and decades of commercial gold production. By exploring in such an environment, the risks associated with the Company’s activities decrease and the opportunities for long-term development increase.

Enhancing an Expanding Portfolio

In addition to exploration at Evelyn, activity at Pilar through the Tocvan partnership, and ongoing optimization of its claims in Sonora, Colibri is developing several other vectors toward discovery. In particular, the location and geological framework of EP represent a meaningful additional vector.

Important Catalysts to Monitor

  • Results of initial assays — confirmation of grade, thickness, and continuity
  • Confirmation of structural linkages — connection between surface trends and deeper systems
  • Discovery of new mineralized zones — expansion of scale
  • Follow-up drilling — evaluation of geometry and consistency
  • Change in investor sentiment — strong results could result in a valuation adjustment to the entire Company

A small number of positive drill intercepts could result in increased attention for EP.

Background on Historical Exploration and Drilling

To date, Colibri Resources has drilled over 12,000 meters of hole at the EP Gold Project, and collected over 2,500 surface samples, while also completing a geophysical study of the area. Surface sampling has demonstrated numerous occurrences of surface rock samples assaying greater than 1.0 g/t Au, including some samples assaying greater than 4.6 g/t Au, thereby demonstrating a gold-bearing system at surface.

Although previous results provide support for a gold-bearing system, much of the structural corridor remains untested. There are several priority target areas that have never been drill-tested, therefore, there exists the potential for this drill program to identify mineralized zones that exist below the surface.

This combination of prior exploration data, combined with the existence of high-potential untested ground creates conditions favorable for making meaningful discoveries at EP.

“With drills turning, we have moved decisively into execution mode. Our team is energized, aligned, and committed to advancing the Project with focus and purpose.

Ian McGavney, President & CEO of Colibri Resource Corporation

Backdrop of the Gold Market — Supporting Wind

The price of gold has reached a record level of approximately $4,200/oz due to a variety of factors including inflationary pressures, uncertainty related to the overall economy, accumulation by central banks, and reduced global supply. This represents one of the strongest bullion markets in recorded history.

For a junior explorer such as Colibri, this gold market environment is particularly supportive:

High gold prices enhance the economic viability of any discovery

Investor interest in exploration news increases during periods of high gold prices

Increased gold prices commonly lead to increased investment capital flowing into small cap miners

When gold prices reach record highs, investors tend to react more quickly and aggressively to news regarding new discoveries.

Conclusion

Colibri Resources (TSXV: CBI / OTC: CRUCF) is entering a time of heightened catalyst activity as drilling commences at the EP Gold Project. Given the fact that it is proximal to a major producer, the presence of positive geological indicators, and the fact that it is located in one of the premier gold-producing regions of Mexico, the Company now possesses a high-leverage opportunity before it.

Should drilling confirm either continuity or scale at EP, the Company believes that EP will become one of the most important assets for Colibri and should act as a significant contributor to shareholder value in the months ahead.
