Unico Silver Strikes High-Grade Silver at New Brunilda Discovery
Unico Silver's Phase 1 drilling program at the Joaquin project has delivered exceptional results, confirming significant extensions to the La Negra silver resource while unveiling a promising new discovery at Brunilda. The 20-hole reverse circulation (RC) drilling campaign, totaling 2,712 metres, has exceeded expectations with multiple high-grade intercepts that validate the company's growth strategy.
La Negra Resource Expansion Delivers Outstanding Silver Grades
The first assay results from La Negra have confirmed substantial extensions to the existing silver resource, with mineralisation remaining open in multiple directions. Impressive high-grade intercepts include:
- 17m at 258g/t AgEq (238g/t Ag, 0.26g/t Au) from 63m in hole JRC002-25, including 1m at 1,213g/t AgEq
- 23m at 268g/t AgEq (238g/t Ag, 0.38g/t Au) from 98m in hole JRC017-25, including 3m at 1,189g/t AgEq
- 15m at 258g/t AgEq (253g/t Ag, 0.1g/t Au) from 38m in hole JRC022-25
These results not only validate historical drilling data but significantly expand the mineralised envelope beyond the current Foreign Estimate. The La Negra system now extends over 2 kilometres in strike length and remains open to the northwest, southeast, and at depth.
"This first round of drilling at Joaquin has delivered an exceptional start. Results from La Negra confirm the tenor and continuity of historical intercepts while successfully expanding the mineralised footprint beyond the current Foreign Estimate. The system now exceeds 2 kilometres in strike and remains open in multiple directions, presenting a compelling case for continued growth." – Todd Williams, Managing Director
New Brunilda Discovery Highlights District-Scale Potential
Perhaps most exciting is the new Unico Silver Brunilda discovery, located 1.5km east of La Negra on a parallel structure. All scout drill holes intersected broad zones of near-surface silver mineralisation, including:
- 23m at 88g/t AgEq (68g/t Ag, 0.25g/t Au) from just 4m depth in hole JRC011-25
- 42m at 54g/t AgEq (44g/t Ag, 0.13g/t Au) from 47m in hole JRC014-25
This Unico Silver Brunilda discovery significantly enhances the district-scale potential of the Joaquin project, suggesting multiple parallel mineralised structures may exist across the property. The near-surface nature of the mineralisation at Brunilda is particularly notable, with high-grade gold and silver intercepts starting from just 4 metres below surface.
Understanding Grade-Thickness: A Key Metric for Silver Deposits
When evaluating silver deposits, one important metric investors should understand is Grade-Thickness (GT), which multiplies the grade by the intercept width. This measurement helps assess the economic potential of a deposit by accounting for both grade and width in a single value.
In Unico's results, we see impressive GT values throughout the drill campaign:
- JRC017-25: 6,173 GT – indicating exceptional metal content
- JRC008-25: 5,184 GT – demonstrating substantial mineralisation
- JRC002-25: 4,400 GT – confirming high-grade potential
Deposits with GT values above 1,000 are generally considered significant, making these intercepts particularly noteworthy for investors. The Unico Silver Brunilda discovery has already demonstrated GT values exceeding 2,000, highlighting its potential economic significance.
Accelerated Growth Strategy Now Underway
Unico Silver has already mobilised a second diamond drill rig to accelerate the exploration program. This strategic addition will:
- Test deeper extensions of mineralisation at all prospects
- Support the definition of a maiden JORC Mineral Resource at La Negra
- Further delineate the new Brunilda discovery
- Systematically drill historical intercepts along the La Morocha structure
The company's approach aims to rapidly expand resources and unlock new mineralised zones across the broader Joaquin district. Furthermore, with promising gold-silver veining being found at other exploration projects across the region, Unico's timing could not be better. With two drill rigs now active, investors can expect a steady flow of results as the exploration program advances.
Joaquin Project: Positioning Within a Premier Silver Portfolio
The Joaquin project complements Unico's existing Cerro Leon silver-gold district, creating a formidable portfolio in Argentina's prolific Santa Cruz province:
| Project | Resource Category | Tonnes (Mt) | AgEq (g/t) | AgEq (Moz) |
|---|---|---|---|---|
| Cerro Leon | JORC Resource | 16.5 | 172 | 91 |
| Joaquin | Foreign Estimate | 16.7 | 136 | 73 |
| Combined | 33.2 | 154 | 164 |
This combined portfolio positions Unico Silver as a leading undeveloped silver company in the region, with significant growth potential through ongoing exploration. In addition, recent lithium exploration in Argentina has uncovered high-grade gold deposits, further highlighting the country's mineral richness. The addition of the Unico Silver Brunilda discovery further strengthens this position by adding a potentially significant new mineralised zone to the company's resource inventory.
Why Investors Should Follow Unico Silver
Unico Silver represents a compelling investment opportunity in the silver sector for several reasons:
-
Resource Growth Potential: With both La Negra and the new Brunilda discovery open in multiple directions, there's substantial room for resource expansion.
-
District-Scale Opportunity: The 35,946-hectare land package contains multiple untested targets, with Brunilda being just the first of many potential discoveries.
-
Experienced Management: The team has a proven track record in South American precious metals exploration and development.
-
Strategic Location: The projects are situated in mining-friendly Santa Cruz province, home to numerous world-class silver and gold operations.
-
Accelerated Development Timeline: With two drill rigs now active, investors can expect regular news flow and rapid resource growth.
With silver prices strengthening amid growing industrial demand and investment interest, Unico Silver is positioned to capitalise on favourable market conditions with its expanding high-grade silver portfolio. Similar to S2 Resources' multi-project campaign, Unico's aggressive exploration approach could yield significant discoveries. Moreover, the ongoing exploration for rare earth elements and critical metals globally highlights the importance of resource diversification, something Unico achieves through its silver-gold focus. The initial success at the Brunilda discovery demonstrates the company's ability to identify and develop new mineralised zones, adding significant value to its project portfolio.
