Moho Resources Ltd (ASX:MOH) has received encouraging assay results from a stream sediment sampling program undertaken in early 2021 at the Burracoppin Gold Project in WA.
The company’s grassroots sampling campaign has identified ten high-priority exploration targets within extensive areas of gold in stream sediment anomalism.
Notably, some anomalies associated with pathfinder elements are coincident with interpreted magnetic structures.
High priority exploration targets
Moho managing director Shane Sadleir said: “The stream sediment survey has successfully identified a number of high priority gold exploration targets within the Burracoppin Project which Moho plans to follow up over the next field season.
“Importantly, the survey has reinforced the gold potential at the Crossroads prospect where we are awaiting assay results from the recent diamond drilling campaign.”
Gold associated with arsenic in stream sediment anomalies.
Other key outcomes
Anomaly 1 which is associated with arsenic-bismuth-zinc-lead-tungsten is the strongest.
In addition, anomaly 2 associated with tungsten and copper is the second strongest.
Furthermore, anomaly 3, situated to the southeast of current drilling at the Crossroads prospect, is the third ranked gold anomaly and is supported by nickel, copper, tungsten and bismuth anomalies along a southeast trend.

Sampling strategy
A total of 369 samples were collected over an area of about 330 square kilometres, representing a sample density of 1 sample per square kilometre.
Bulk samples were collected in the field at spacing determined by watercourse locations and land access.
Samples were submitted to Intertek where they were sieved to a fraction passing – 75µm, with analysis were by 5 grams aqua regia for gold and a multi-element suite.
The stream sediment sampling and assay program was designed and supervised by Moho’s consultant geochemist Richard Carver of GCExplore Pty Ltd.
Importantly, the interpretation of the results by Carver involved creating line vectors representing the stream segment for each sample, which allowed the catchments to be contoured.
Gravity survey
A high-resolution gravity survey has been completed across E70/5300, with survey stations nominally spaced on a 500x500-metre grid across the entire tenement.
The imminent interpretation of the data will assist with Moho’s understanding of the Burracoppin Project, with the potential to identify buried intrusions and add to the structural interpretation across the tenure, as well as an improved perception of the regional geological setting.
The company has also been granted additional tenure, E70/5299 and E77/2671, which increases the size of Burracoppin Project by 12%. Two of the new gold anomalies are on the former.
Next steps
- Soil sampling on a 400x100-metre pattern to cover the higher priority anomalies;
- Interpretation of gravity data on E70/5300;
- Diamond core assays due this quarter;
- Project scale geological interpretation; and
- Aircore drilling to test anomalies Q1 2022.
