Slide 3: Recap: Why North Rukwa / Nyasa Fairway?
Recap: Why North Rukwa / Nyasa Fairway? For personal use only 01 Probably the world’s most prolific helium province (100% NHE acreage). 1 0.3% is average of all USGS He occurrences (N>16,000). 7.4% is Average helium percentage the average of Tanzanian Type-II (crustally derived, minor methane) Heliu
Slide 4: Recap: Original Mbelele shallow appraisal
Recap: Original Mbelele shallow appraisal: data points. For personal use only • Not a typical O&G type target • Gas bubbling in mud returns from ~80m. • Gas bubbling ceased on mud weight increase. • Pressure change from mud weight increase indicative of ~20m gas column. • Helium significantly above
Slide 5: Recap: Mbelele shallow appraisal: probable free gas cap
Recap: Mbelele shallow appraisal: probable free gas cap. For personal use only • Starting around 85m. • Structure approximately 9km by 4km. • Estimated 20m free gas column. • Very high permeability and excellent porosity ie very high flow potential. • Structure completely onshore of Lake Rukwa and e
Slide 6: Potential Additional Targets (a very gassy lake margin)
Potential Additional Targets (a very gassy lake margin) For personal use only ✓ Yes - The right conditions shallow gas occur onshore along the western margin ✓ 8 shallow onshore potential targets identified. • Low-cost, “best tech” strategy is key • Quick low-cost shallow geophysics program - mature
Slide 7: Mbelele shallow-gas: not 'one of a kind'
Mbelele shallow-gas: not ‘one of a kind’ Shoreline trends NNW ✓ He in soil gas (H2 not measured) For personal use only Fault trends onshore • Post-drilling revision of NHE’s 2023 seismic Note very Shallow gas zones move shallow data onshore • Most onshore, shallow-gas potential is not “muted” Region
Slide 8: Required Field Work
Required Field Work Not like conventional O&G (cheaper, quicker) For personal use only • Two complimentary methods (all onshore) • Shallow seismic (refl. & refr.) • Electrical resistivity • Simple, quick and low-cost using existing local team and equipment. • Team from University of Dar es Salaam wi
Slide 9: Drilling & Testing
Drilling & Testing For personal use only • Final target definition after geophysics. • Site prep minimal. • Drilling each well ~2-3 days and 2-3 days to relocate to next well. • 2 specialised, low-cost well-heads, to measure gas flow & composition on order. • Testing estimated* <10 days (off-rig). •
Slide 10: What about Natural or "White" Hydrogen?
For personal use only What about Natural or “White” Hydrogen ? (piecing it all together) ASX NHE 10 Green helium for a hi-tech world noblehelium.com.au
Slide 11: The usual Helium and hydrogen generation processes
The usual Helium[1] Must have … Basic generation processes He & H2 ✓ Uranium / Thorium ✓ Time++ = He nucleus ✓ Groundwater For personal use only ✓ Pressure, depth, temp. ✓ Advective flow / gas migration Hydrogen from “Serpentinisation”[3],[4] 3Fe2+ (in olivine) + 4H2O → Fe3O4 (magnetite) + 4H2 Mus
Slide 12: Double Hydrogen Potential
✓ The right basement terrains continue under the modern lake. Double Hydrogen Potential ✓ Ongoing H2 generation feasible. ✓ Active migration focus to gassy western • Very favourable geology for natural or lake margin. For personal use only “White” hydrogen. ✓ Local structures and seals. • Significan
Slide 13: Value in hydrogen?
Value in hydrogen? ✓ H2 a core ingredient of NH3 & Urea Would it be price competitive ? For personal use only • (usually from converting CH4 to H2 “Grey”) ✓ White[5] Green[4] Grey[6] ✓ Standard, scalable technology Prod. cost $0.50 - $1.00 $3.00 - $7.50 $0.98 - $2.93 US$/kg • Example: Urea => N2 bas
Slide 14: Recap: full fairway cross-section with stacked plays
Recap: full fairway cross-section with 4 x stacked plays (colours) 2024 => the shallow “gassy” western margin … still a small fraction of the whole Chisi Shear Zone1 For personal use only (magnetic anomaly) Multiple shallow gassy margin appraisal targets Increasing He% Decreasing risk Chilichili Pro
Slide 15: Updated gassy margin appraisal plan / Longer Term Opportunity
Updated “gassy margin” appraisal plan Longer Term Opportunity WHAT ARE WE GOING TO DO (updated & expanded): POST SUCCESSFUL SHALLOW GAS APPRAISAL: Finalise locations for ~5 shallow gas appraisal targets. Finalise design and commercial arrangements (~6 months): For personal use only • • • Drill and t
