“Moho’s exploration team continue to make excellent progress at East Sampson Dam. The initial phase 2 RC drill results extend gold mineralisation down plunge at the southern end of the prospect and highlight the potential to discover additional gold mineralisation at the prospect”
Mr Shane Sadleir, Moho Managing Director
Moho Resources Ltd (ASX:MOH) ( Moho or Company ) is pleased to announce encouraging results for the first 9 holes of 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, M27/263 (Figure 1).

PHASE 2 RC DRILLING RESULTS
Phase 2 of the current resource infill drilling program finished in early January 2021 and totalled 45 holes for 3,850m of drilling (Table 1). Refer to Figure 2 for final drill hole collar locations in relation to gold projected to the surface as outlined from previous Moho drilling. This release will discuss available assay results for the first 9 drillholes, SSMH0102 to SSMH0110 which cover the southern quarter of the ESD gold prospect.

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 continues to experience long delays of up to 8 weeks in receiving assay results from Perth assay laboratories. Additional ESD RC assay results will be reported as they become available.

SSMH0102
This hole (Figure 3) confirmed moderate grade mineralisation previously found in ESR235 with 1m @1.32 g/t Au, which is higher than previously located. Moho geologists believe this mineralisation is spatially related to low angle east dipping structures and may be the continuation of high-grade mineralisation discovered in SSMH0049. It was also successful in extending high grade mineralisation down plunge from SSMH0051 on section 6637680 to the north with 1m @ 8.31 g/t Au from 100m down hole. This mineralisation sits on the lower contact of black shale against a narrow quartzporphyry (leucotonalite) unit.
SSMH0103
This hole (Figure 3) successfully extended the high-grade mineralised pod, 20m down dip from SSMH102 with 3m @ 1.13 g/t Au in black shale beneath andesite.

SSMH0104
The drill hole (Figure 4) was designed to clarify mineralisation located in an historical RAB hole (ESR054) and confirmed low grade mineralisation with 1m @ 0.79 g/t Au in tuff.
SSMH0105
SSMH0105 (Figure 4) was designed to explore down dip of mineralisation previously found in SSMH0051 and SSMH0062. It intercepted additional high-grade mineralisation of 6m @ 2.3 g/t Au from 105m downhole, including 1m @ 3.63 from 105m and 1m @ 6.80 g/t Au from 110m. The highgrade intervals are hosted in quartz-porphyry (leucotonalite) and tuff.

SSMH0106
This hole was designed to explore structures believed to be offsetting high grade shoots in the western wall of the preliminary Whittle pit shell successfully locating quartz veins associated with an NNE trending fault.
SSMH0107
SSMH0107 was also drilled in the western section of the preliminary Whittle pit shell to essentially sterilise the area. It did not intersect any gold mineralisation > 0.5 g/t Au.
SSMH0108
This hole (Figure 5) targeted the inferred southerly plunge extension of shallow high-grade intersections on section 6637740 to the North but failed to locate mineralisation. It is now believed the mineralisation may have been truncated and offset to the west by an NNE trending fault. Further drilling at a later date will be required to test for this mineralisation.
SSMH0109
This eastern hole on section 6637720 (Figure 5) explored for mineralisation down dip of grade previously located in SSMH0081 and MRC012. SSMH0109 intersected 2m @ 2.98 g/t Au including 1m @ 5.26 g/t Au hosted by quartz veins in tuff. This extends the mineralised pod containing the SSMH0081 and MRC012 intercepts 12m down dip and has successfully delineated this mineralisation on the southern side of an NNE trending fault.

SSMH0110
This hole drilled in the east targeted the southerly down plunge extensions to high grade mineralisation 20m north in SSMH0056 on section 6637760 (Figure 6). SSMH0110 intersected 2m @ 2.61 g/t Au from 61m including 1m @ 4.27 g/t Au from 62m. In addition, it located moderate grade mineralisation of 1m @ 1.71 g/t Au from 111m on the underside of a quartz vein in quartz-porphyry. This drill hole, like SSMH0109, has successfully delineated new mineralisation on the southern side of an NNE trending fault in a previously untested area.

GEOPHYSICAL LOGGING OF RC HOLES
Following the completion of drilling at East Sampson Dam in January 2021, Moho contracted Wireline Services Ltd from Perth to undertake down hole logging with geophysical probes of the 7 diamond holes and 10 RC holes. The output from this work was magnetic susceptibility, density and calliper, as well as televiewer (optical and acoustic) data for each hole. These data will be used to elucidate structural information and rock density to aid resource modelling and planning of further drill holes.
METALLURGICAL TESTWORK
JT Metallurgical services of Perth have been commissioned to finalise sighter testwork started in 2020 and prepare a master composite of likely mill feed from the ESD prospect and complete testwork as soon as possible. Moho has also been in discussions on parameters for phase 2 testwork using diamond drill core or current high-grade RC samples.
==> picture [596 x 68] intentionally omitted <==
GEOTECHNICAL INVESTIGATIONS
Consultant geotechnical engineer Mike Turner has been commissioned to prepare a report on the structural integrity of the rocks at ESD. This work will analyse all the available structural data to assess the competency of the rocks to support pit wall stability design for a future pit. This data will also be critical in defining the potential angles of the pit walls.
The East Sampson Dam gold Project is well located close to existing gold processing facilities and mining infrastructure. Moho believes that, if a suitable gold resource is established, it could provide important cash flow for the Company.
