Megado Minerals Confirms High-Grade Copper-Silver Discovery at Iberian Project
Megado Minerals Limited (ASX: MEG) has reported exceptional rock chip assay results from its Iberian Copper Project in northern Spain, with multiple samples returning over 5% copper and 100g/t silver. The standout result of 16.41% copper and 147g/t silver (4.7oz/t) highlights the project's potential for Megado Minerals Ltd to discover high-grade copper-silver deposits of significant scale.
The results span a 7-kilometre strike length within the vicinity of the historic Mina Emilia mine, demonstrating the scale of mineralisation across the 956km² project area. Furthermore, with a maiden drilling programme targeted for Q2 2026, Megado Minerals positions itself at the forefront of European exploration for high-grade copper-silver discoveries.

Outstanding Assay Results Across Multiple Historic Mines
The rock chip sampling programme has delivered consistently high-grade results across the project area. Moreover, these results validate the regional potential for substantial copper-silver deposits.
Western Permits (Including Mina Emilia):
- 16.41% Cu and 147g/t Ag (4.7oz/t) – Sample 172-05-01
- 10.59% Cu and 124g/t Ag (4.0oz/t) – Mina El Monte
- 9.66% Cu and 141g/t Ag (4.5oz/t) – Mina Emilia
- 9.49% Cu and 150g/t Ag (4.8oz/t) – Sample 172-04-01
- 6.22% Cu and 99g/t Ag (3.2oz/t) – Sample 171-13-01_2
Central and Eastern Permits:
- 6.69% Cu and 67g/t Ag (2.2oz/t) – Mina Sagarillo
- 3.78% Cu and 96g/t Ag (3.1oz/t) – Mina Calixto
The consistency of high-grade results across at least 12 historic copper mines and over 50 copper occurrences validates the regional potential. In addition, these results demonstrate the opportunity for Megado Minerals Ltd to discover high-grade copper-silver deposits of economic significance.
Multiple samples returned over 5% copper and 100g/t silver, with the standout result of 16.41% copper and 147g/t silver demonstrating the project's potential for world-class sedimentary-hosted copper-silver deposits.
Understanding Sedimentary-Hosted Copper Deposits
Sedimentary-hosted copper deposits, also known as "red beds" or "Lisbon Valley" type deposits, represent one of the world's most significant sources of copper. These deposits form when copper-rich fluids migrate through sedimentary rocks and precipitate copper minerals where they encounter organic matter or other chemical barriers.
Key Characteristics Include:
- Formation in continental sedimentary environments through fluid migration
- Association with prominent geological structures that channel mineralised fluids
- Potential for both oxide and sulphide mineralisation at different depths
- Historical examples include major deposits in the southwestern United States
For instance, these deposit types are particularly attractive to investors because they can host large tonnage, bulk-mineable ore bodies with consistent grades suitable for open-pit mining operations. However, the Iberian project targets the same geological processes that created these world-class deposits.
Strategic Project Position in Historic Mining District
The Iberian Copper Project benefits from its location in a historically productive mining region where copper extraction occurred during the 19th and 20th centuries. Furthermore, the project targets Oligocene-aged sandstone and conglomerate formations deposited in ancient river environments.
| Project Metrics | Details |
|---|---|
| Total Area | 956km² across 12 permits |
| Historic Production | 19th and 20th century copper oxide mining |
| Geological Setting | Oligocene-aged sandstone and conglomerate |
| Mineralised Strike | 7+ kilometres of confirmed mineralisation |
| Previous Work | Government and Glencore (formerly AZSA) studies |
The project targets the same geological sequence that historically produced copper through small-scale mining operations. However, modern exploration techniques and larger-scale development potential could unlock significantly greater resources than previous operators achieved.
Historical studies by the Spanish Government and Asturiana de Zinc (now Glencore) identified the regional copper potential during the 1970s. In addition, these studies recorded multiple copper occurrences across the prospective stratigraphic sequence, providing a foundation for the current systematic exploration approach.
What Are the Upcoming Catalysts and Development Timeline?
The announcement outlines a systematic exploration approach leading to maiden drilling. Moreover, this timeline provides clear milestones for investor tracking.
Immediate Activities (Q1 2026):
- Analysis of completed high-resolution aeromagnetic survey results
- Structural interpretation to identify mineralising controls
- Induced Polarisation (IP)/Resistivity surveys at Mina Emilia
Key Milestone:
- Maiden drilling programme commencement in Q2 2026
The IP/Resistivity survey represents a particularly important step, as it could identify copper sulphide accumulations at depth below the water table. Furthermore, the company hypothesises that copper sulphides may have accumulated in oxygen-poor environments at depth, potentially indicating larger disseminated deposits beyond the historic shallow oxide workings.
The Company hypothesises that copper sulphides may have accumulated at depth below the water table in anoxic environments and the sulphides may be reflected by zones of increased chargeability in the IP/resistivity survey.
Investment Thesis: Multi-Asset Exploration Portfolio
Megado Minerals presents investors with exposure to multiple high-potential projects across different commodities and jurisdictions. In addition, this diversification provides multiple pathways to value creation.
| Project | Commodity | Location | Status |
|---|---|---|---|
| Iberian Copper | Cu-Ag | Northern Spain | Pre-drilling |
| Alpartir Silver-Copper | Ag-Cu-Sb | Northern Spain | Acquisition pending |
| North Fork REE | Rare Earths | Idaho, USA | Under option to Iluka |
| Cyclone Lithium | Li-Au | Quebec, Canada | 100% owned |
The Spanish copper-silver projects provide near-term drilling catalysts in a politically stable, mining-friendly jurisdiction with established infrastructure and skilled workforce. Furthermore, Spain offers advantages including existing mining legislation, proximity to European markets, and established mineral processing capabilities.
The diversified portfolio approach reduces single-asset risk while providing exposure to multiple in-demand commodities including copper, silver, lithium, and rare earth elements.
