EcoGraf’s AngloGold Farm-In Hits First Field Milestone With 2,659 Gold Samples
Key Takeaways
- AngloGold Ashanti has completed a 2,659-sample soil geochemistry program on a 200 m × 1,000 m grid across all three Golden Eagle licences, with samples submitted to SGS Mwanza for gold and multi-element analysis.
- The program is the first major field milestone of AGA's US$9.0 million, 5-year farm-in agreement commenced December 2025, with drilling scheduled for Year 2 of the agreement.
- The sampling area covers the interpreted northeast continuation of the Banded Iron Formation hosting the Winston gold deposit, which previously returned intercepts including 16 m @ 55.23 g/t gold from 116 m.
- Southern Frontier has returned exceptional early results — including 8,820 ppb gold and visible gold in 5 of 16 stream sediment samples — from just 8 km² of a 588.5 km² project area, with the Company drawing analogies to the 1.0 Moz Handeni and 1.1 Moz New Luika deposits.
- Gold has surpassed US$4,500/oz with Morgan Stanley and UBS both forecasting prices above US$5,000/oz for 2027, while Tanzania's Fraser Institute jurisdiction ranking has improved from 76th of 76 in 2019 to 34th of 68 in 2025.
AGA completes 2,659-sample geochemical program at Golden Eagle as EcoGraf’s exploration pipeline builds
EcoGraf Limited has confirmed that AngloGold Ashanti (AGA) has completed an extensive soil geochemistry sampling program across all three Golden Eagle licences, marking a key field milestone delivered during the first year of the US$9.0 million, 5-year farm-in agreement that commenced in December 2025. With 2,659 samples now submitted to SGS Mwanza for gold and multi-element analysis, this is not a preliminary gesture — it is a systematic, project-wide data collection effort that sets the stage for drill target generation.

What is a soil geochemistry program — and why does it matter for investors?
Soil geochemistry sampling involves collecting surface material on a defined grid across a project area, then sending those samples to a laboratory for gold and trace-element analysis. The resulting data is mapped to identify geochemical anomalies — elevated concentrations that suggest mineralisation below the surface. It is the standard first step in a structured exploration program because it tells explorationists where to focus before committing the far greater cost of drilling.
At Golden Eagle, the 2,659 samples were collected on a 200 m × 1,000 m grid covering the entire project area. Results will be used to identify initial gold anomalies, guide close-spaced follow-up sampling, and ultimately underpin drill target selection. In parallel, AGA has commenced preparation for a high-resolution UAV magnetics geophysical survey across the project area. The combination of geochemical and geophysical data, together with detailed geological mapping, is intended to support planning for the initial Golden Eagle drilling program, which is scheduled for the second year of the Agreement.
The ground being sampled is directly relevant to the investment thesis. The sampling area covers the interpreted northeast continuation of the Banded Iron Formation (BIF) that hosts the Winston gold deposit — the same formation that, according to a Tanga Resources ASX announcement from July 2017, returned drill intercepts including 16 m @ 55.23 g/t gold from 116 m. AGA is spending its own capital to generate targets before EcoGraf spends a dollar on Golden Eagle drilling.
The US$9M AngloGold investment at Golden Eagle was structured as a 5-year farm-in, giving AGA the right to earn into the project by funding systematic exploration before EcoGraf commits its own capital to drilling.
Four-project portfolio — the full Golden Frontier picture
Golden Eagle is one of four projects within EcoGraf’s Golden Frontier portfolio, covering more than 3,000 km² across Tanzania. The broader portfolio spans gold, copper, nickel, lithium, and tungsten, with each project at a different stage of activity.
| Project | Commodity Focus | Key Highlight | Next Step |
|---|---|---|---|
| Golden Eagle | Gold | 2,659 soil samples collected; farm-in with AGA (US$9.0M, 5 years) | Results pending; UAV magnetics survey preparation underway; drilling in Year 2 |
| Southern Frontier | Gold, Nickel | 8,820 ppb gold (maximum stream sediment); visible gold in 5 of 16 samples; 4.45 g/t rock chip; +3 km anomaly, open in both directions; only 8 km² of 588.5 km² covered to date | Expanded stream sediment sampling (+1,000 samples), UAV magnetics (1,000 line-km), maiden drill targeting |
| Western Frontier | Copper, Gold | 6 priority Cu-Au prospects; proximal to RMI’s Mpanda Cu-Au discovery (same geological setting; maiden 2,500 m drill program underway; RMI market cap A$150M at 4 September 2026); GoT has designated region a priority copper exploration area | Initial ground truthing of priority prospects |
| Northern Frontier | Nickel, Lithium, Tungsten, Gold | 6 priority prospects; same belt as world-class Kabanga Nickel Sulphide Project; geological setting analogous to Rwanda’s lithium pegmatite fields; extensive historical dataset acquired (BHP, UNDP, 2000–2011 data) | Multi-commodity geochemical and geophysical first-pass surveys |
Southern Frontier deserves particular attention given how early the program remains. Only 8 km² has been sampled to date, representing just 0.01% of the 588.5 km² project area, yet the maiden reconnaissance program has already returned exceptional results. The Company considers the Southern Frontier results to demonstrate potential for a discovery analogous to the Handeni (1.0 Moz) or New Luika (1.1 Moz) gold deposits.
The exceptional Tanzania results from the Southern Frontier reconnaissance program stand out given the minimal coverage achieved to date, with visible gold reported across multiple stream sediment samples well before systematic infill sampling has begun.

Supportive backdrop — gold at US$4,500/oz, Tanzania rising as a mining jurisdiction
The macro environment adds further context to the pace of activity across the portfolio. Gold has surpassed US$4,500/oz, and Morgan Stanley and UBS have both forecast prices above US$5,000/oz for 2027. Record copper and tungsten prices are also relevant to the Western and Northern Frontier projects, where EcoGraf holds prospective ground in both commodities.
Tanzania’s investment climate has improved materially over recent years:
- Fraser Institute ranking improved from 76th of 76 jurisdictions in 2019 to 34th of 68 jurisdictions in 2025
- Mining sector contribution increased to 10.3% of GDP in 2025, up from 7.8% the prior year
- Mineral exports reached approximately US$5.4 billion
- Bank of Tanzania gold reserves reached 27.5 tonnes by June 2026
Funding for the Frontier exploration program is linked to the recently announced underwritten Share Purchase Plan (SPP), announced 3 September 2026. A portion of the funds raised through the SPP is intended to be allocated to commencing exploration across the Tanzanian gold projects, subject to the successful completion of that raise. EcoGraf has noted that the SPP is open and eligible shareholders are encouraged to submit applications early to allow sufficient time for processing before the closing date.
It is worth noting that EcoGraf’s primary focus remains the advancement of the Epanko Graphite Project and its vertically integrated HFfree Battery Anode Materials business. The Golden Frontier portfolio provides near-term exploration upside alongside that critical minerals core, rather than replacing it.
