“The latest RC drilling results have identified a number of high-grade mineralised intervals and new mineralised zones at the East Sampson Dam gold prospect. This new information, in combination with the ongoing structural control interpretation and geological modelling by Moho’s geologists and consultants, provides further confidence that the prospect has the potential to generate a suitable gold resource which could provide important cash flow for the Company”

Moho Resources Ltd (ASX:MOH) ( Moho or Company ) is pleased to announce the identification of additional high grade gold zones during the Phase 2 reverse circulation (RC) drilling program as part of its resource definition studies, to infill and extend gold mineralisation at the East Sampson Dam (ESD) prospect on M27/263 (Figure 1).

NEW PHASE 2 RC DRILLING RESULTS
Results from an additional twelve holes, SSMH115-SSMH0126 (Table 1), have been received and contain a number of significant high grade mineralised intervals and new mineralised zones. Figure 2 shows drill hole collar locations in relation to the gold mineralising envelope projected to the surface. This release discusses the available assay results for the drillholes above that cover infill RC drilling in the central portion of the ESD gold prospect.

Figure 2: Phase 2 ESD RC drill program collars in relation to known mineralised zones
The drilling highlighted a number of significant gold intersections (Table 2, Figure 2). All holes were sampled with a primary and duplicate sample collected on a 1m basis from the cone splitter. All samples were analysed at Bureau Veritas Laboratories Perth by 40g fire assay and AAS finish, with certified reference material (CRM) inserted every 33 samples and duplicates assayed every 50 samples throughout the program.

Moho has experienced long delays of up to 8 weeks in receiving assay results from Perth assay laboratories, in part due to several pallets of samples being erroneously shipped to Adelaide in late December. Additional ESD RC assay results will be reported as they become available.

Notes:
1. Intercepts are an aggregation of 1m intercepts ≥0.5 g/t Au with up to 1m of internal dilution
- 2 Results are based on a 1m samples from RC rig cone splitter.
3. Samples were assayed for gold using 40g charge fire assay with AAS finish.
4. Sample intervals are down-hole and true widths are yet to be determined.
SECTION 6637800N
Hole SSMH0116 (Figure 3) discovered 1m @ 1.95 g/t Au in ferruginised quartz veins at the contact between porphyry and tuff. This extends the medium grade mineralisation intersected in SSMH0088 another 20m up-dip. The middle hole on this section SSMH0117 broadened and extended mineralised intervals into saprock with intervals of 1m @ 1.54 g/t Au, 1m @ 1.64 g/t Au and 1m @ 9.6 g/t Au on the contact between tuff and black shale. This high grade intercept is the northern, upplunge extension of the very high grade mineralisation (1m @ 15.0 g/t Au) intersected in MRC020 on 6637780N.

==> picture [596 x 68] intentionally omitted <==
SECTION 6637820N
Hole SSMH0119 (Figure 4) discovered high grade Au mineralisation (1m @ 4.04 g/t Au) associated with brecciated quartz veins in massive goethite altered tuff. The low grade Au intercept (~0.5 g/t) in SSMH0119 is associated with an interpreted low angle NW trending structure. On section 6637800N both SSMH0115 & 116 have similar low grade intercepts in the same structural position. Other holes on these and other cross sections that have intersected this structure also contain higher grades of mineralisation.

Figure 4: ESD cross section 6637820N (looking north) showing drilling and mineralised grade shells
SECTION 6637840N
Drilling on this section (Figure 5) discovered a number of new medium and high grade Au intersections that are expected to extend mineralised grade shells and enhance tonnages. Shallow mineralisation in SSMH0122 from 32m will extend grade shells up dip towards the surface while deeper mineralisation of 4m @ 1.49 g/t Au and 1m @ 1.96 g/t Au extends mineralisation for 30m between SSMH0067 and 68.

==> picture [458 x 457] intentionally omitted <==
Figure 5: ESD cross section 6637840N (looking north) showing drilling and mineralised grade shells
New shallow gold intersections in SSMH0123 link with new intersections in SSMH0122 and historical mineralisation in Mt Kersey hole GINB0668 to extend modelled shoots on the eastern side of the prospect. Broad intersections of high grade gold mineralisation deeper in SSMH0123 (6m@ 3.57 g/t Au, including 1m @ 15.6 g/t Au) are related to a sheared porphyry and associated quartz veins intruding into tuff. This broad intercept significantly enhances known mineralisation in the area and may justify deepening the modelled pit in this central section of the prospect.
SECTION 6637860N
Results on this section (Figure 6) show new high grade mineralised zones and enhanced shallow mineralisation in SSMH0126 with 3m @ 1.26 g/t Au, including 1m @ 2.62 g/t Au in the oxide zone. At 47m, broad high grade mineralisation of 5m @ 5.95 g/t Au including 1m @ 15.2 g/t Au and 1m @ 11.1 g/t Au is a significant new zone. The individual very high grade intercepts are associated with ferruginised quartz veins in saprolitic tuff in close proximity to an intruding porphyry.

STRUCTURAL MODELLING OF FAULTS AT ESD
Structural modelling of the ESD prospect is ongoing. Work to date has focussed on structures observed in diamond drill core and recognised in RC drill chips and tracing them from section to section using the geological information in the drill logs. This is an iterative process that has generated many queries and necessitated relogging of drill chips from some RC drill holes.
Down hole televiewer data has been acquired and received for all the diamond drill and selected RC holes over the length of the mineralised envelope. The data is being reformatted for import into the database. The next stage will be to import this data for the relevant drill holes to compare the interpreted structures with those captured by the televiewer.

The East Sampson Dam gold Project is well located close to existing gold processing facilities and mining infrastructure. Moho believes that establishment of a suitable gold resource could provide important cash flow for the Company.
