Discovering Gold at Haranga Resources Ltd Lincoln Project Deep Drilling

Haranga Resources Scores Major Gold Discovery Beneath Lincoln Project

Haranga Resources (ASX: HAR) has delivered a significant breakthrough at its Lincoln Gold Project in California, with deep drilling revealing strong visual indicators of gold mineralisation extending over 150 metres below the current known system. This represents the first diamond drilling campaign at Lincoln-Comet in over 12 years and marks a critical milestone in discovering gold at Haranga Resources Ltd and unlocking the project's full potential.

According to the announcement, the company has completed over 3,100 metres of HQ diamond core drilling across 44 holes, with encouraging signs that the mineralised system may repeat at depth. This characteristic is typical of the Mother Lode Gold Belt, where mineralisation is known to extend as deep as 2,000 metres below surface.

What Does the Deep Drilling Reveal?

Two strategic deep holes designed to test for mineralisation repetitions have returned highly encouraging results, the company reports:

DDH0280 (191.0m depth):

• Main zone of interest: 160-176.6m downhole
• Within wider 34m zone of alteration and veining (152.6-186.1m)

DDH0281 (328.5m depth):

• Main zone of interest: 144.5-155.4m downhole
• Within wider 20m zone of alteration and veining (144.5-164m)

Both zones are reported to have encountered significant alteration, silicification, veining and sulfide mineralisation – all key indicators of gold-bearing systems. Furthermore, Chairman Michael Davy emphasised the strategic importance, noting that visual indications thus far support the view that Lincoln may host additional sources of mineralisation below the current known footprint.

"Visual indications thus far support our view that Lincoln may host additional sources of mineralisation below the current known footprint," said Michael Davy, Chairman.

Understanding Visual Mineralisation Indicators

Visual mineralisation indicators in gold exploration include quartz veining, sulfide minerals (like arsenopyrite), and rock alteration patterns. However, whilst assays are required to confirm grades, these visual signs typically correlate with gold presence in Mother Lode-style deposits.

The process of discovering gold at Haranga Resources Ltd involves systematic identification of these geological markers before laboratory confirmation. In addition, the company's approach demonstrates thorough understanding of Mother Lode geology and exploration techniques.

How Will Comprehensive Results Pipeline Build Momentum?

The announcement states that Haranga has positioned itself for a steady flow of news over the coming months, with multiple catalysts lined up:

Growth Opportunities

The company has outlined further growth opportunities including additional deep and targeted drilling scheduled for July 2025. Moreover, additional exploration targets across the 6km strike length are planned for the second half of 2025.

According to the announcement, the company is converting its existing non-compliant NI 43-101 resource of 958,910 tonnes @ 9.29 g/t Au (~286,000 ounces) to JORC standards. Additionally, they are exploring opportunities to apply lower cut-off grades given the supportive gold price environment.

What Infrastructure Advantage Creates Development Pathway?

Unlike typical exploration projects, Lincoln benefits from approximately $90 million of prior capital investment that dramatically reduces future development risk, according to the company:

This infrastructure foundation provides Haranga with a significant head start compared to greenfield projects, potentially accelerating the pathway to production once resources are defined. For instance, the existing infrastructure represents a substantial advantage in the process of discovering gold at Haranga Resources Ltd, as it eliminates many typical development hurdles.

How Does Exploration Success Build Resource Base?

The company recently announced its first Exploration Target at South Spring Hill, demonstrating the broader potential across the Lincoln system:

South Spring Hill Exploration Target

1.16Mt to 1.64Mt at 5.4 g/t Au to 5.8 g/t Au

202,000 to 308,000 ounces contained gold potential

Located near existing Stringbean Alley Decline

This target sits within just 2km of the total 6km strike length controlled by Haranga, highlighting the significant upside potential for additional discoveries across the broader project area. Consequently, the exploration target supports the ongoing success in discovering gold at Haranga Resources Ltd across multiple zones.

Understanding Mother Lode Gold Systems

What Makes Mother Lode Special?

The Mother Lode Gold Belt represents one of the world's most famous gold-producing regions, stretching approximately 190km through California's Sierra Nevada foothills. These deposits are characterised by:

• Structural Control: Gold occurs in quartz veins within major fault zones
• High Grades: Deposits often contain exceptional gold concentrations
• Depth Continuity: Mineralisation extends to considerable depths (up to 2,000m)
• Multiple Zones: Systems typically contain several parallel mineralised structures

The Mother Lode Gold Belt has produced over 40 million ounces historically, and Lincoln sits within one of the richest sections of this world-class gold system.

Geological Advantages at Lincoln

The Lincoln Project benefits from typical Mother Lode characteristics including structurally controlled mineralisation, proven high-grade zones, and the potential for multiple mineralised levels. Furthermore, the recent deep drilling confirms these systems may extend significantly below current known mineralisation.

Investment Thesis: Positioned for Multi-Million Ounce Potential

Chairman Michael Davy's vision positions the company for significant growth: "We believe that the Motherlode system has the potential to evolve into a high-grade, multi-million-ounce gold project, and we intend to fully unlock this potential."

With deep drilling confirming mineralisation extends well beyond current resources, upcoming JORC resource definition, and substantial existing infrastructure, Haranga is positioning Lincoln as a potential major gold development project. In addition, the combination of high-grade mineralisation, proven infrastructure, and significant expansion potential creates a compelling investment proposition in the current gold market environment.

Key Investment Tracking Points

• May 2025: Deep drilling assay results could confirm major resource expansion
• JORC Resource: First compliant resource estimate provides valuation foundation
• Additional Drilling: July programme will test further depth extensions
• Resource Growth: Multiple exploration targets across 6km strike length

Why Is This a Unique Gold Investment Opportunity?

Haranga's Lincoln Gold Project stands out in the current gold exploration landscape for several compelling reasons:

1. Proven High-Grade System: The existing resource averages 9.29 g/t Au – substantially above typical gold project grades

2. Infrastructure Advantage: $90 million of existing infrastructure dramatically reduces capital requirements and development timeline

3. Established Production History: The project has successfully produced gold, proving both geological and operational viability

4. Expansion Potential: Deep drilling confirms the system may extend significantly below current known mineralisation

5. Strategic Location: Situated in California's legendary Mother Lode Gold Belt with established mining history and infrastructure

6. Permits in Place: Key operational permits already secured, reducing regulatory risk

Haranga Resources has positioned itself at the forefront of California gold development, with Lincoln representing one of the most advanced, high-grade projects in the Mother Lode Belt. However, with multiple near-term catalysts and significant infrastructure advantages, the company deserves close attention from gold investors seeking exposure to a potential multi-million-ounce development story.

The systematic approach to discovering gold at Haranga Resources Ltd, combined with the substantial existing infrastructure, positions the company uniquely in the California gold sector. Moreover, the upcoming assay results from deep drilling could potentially transform the project's resource profile and development timeline.
