Hardrock mineral exploration introduces a highly precise catchment analysis survey, marking the initial phase of our discovery journey. By collecting the ultra-fine sediments laid down during flood events, we gather materials over a 100m span on levy banks and terraces, ensuring we capture the finest deposits from the catchment domain.

The use of ultrafine drainage samples, similar to a method used by the GGMC in South America that captures gold,copper,silver,REE’s and other element nano-particles created during tropical weathering will be used to screen the tenure and surrounds seeking gold and potentially other commodities. The sample catchments are planned using NASA sourced digital elevation data (SRTM) and modern GIS applications. The geochemical programs will utilize in-field analytical techniques, backed up by commercial laboratory low detection limit BLEG gold (0.1 ppb Au DL) and multi-element analysis (AR + ICP MS/OES). 

The hypothesis is that the drainage fines are the most representative sample, being less biased than sampling, for example traps sites. Having a broad suite of elements will aid in the identification of various mineralisation styles (sediment hosted, epithermal, porphyry, orogenic, etc) and the most significant anomalies and not only locate narrow high grade vein systems. The geochemical results will be combined with geological interpretation, observations and targeting concepts and models.

This survey presents a comprehensive mineral profile of placer deposits, pinpointing potential anomalies and zones of interest within the catchment. Contrasting traditional stream sediment surveys, often criticized for inconsistencies, our methodology guarantees:

• Consistent and Reliable Data: Our data stands the test of time. Revisiting a sample site even years later yields consistent findings.
• Comprehensive Assays: Our reports capture the total percentage of pivotal commodities within the catchment, addressing both coarse and ultra-fine deposits.
• Sub-PPB Accuracy: For critical commodities like Gold, Copper, Silver And REE’s our results are spot-on.
• Rapid Hotspot Identification: Quickly discern potential zones of interest, helping eliminate non-prospective areas. This efficiency trims down exploration duration, fast-tracking your path to discovery.
• Cost Efficiency: By streamlining the exploration process, we help you circumvent unwarranted expenses.
• Mineral Suite: able to assay for gold, copper, multi elements and Rare Earth Elements.

Conducted with the same process used for our catchment basins we do a regolith fine soil analysis over a 100-250 meter grid (depending on elevation) to quickly identify the source of our stream anomalies. 

We tighten our soil grids down to below 50 meter spacings this will effectively outline the anomaly. Especially effective for gold exploration alongside DetectORE as we can provide same day results we can effectively become reactive with results and tighten grids within days instead of months.

In addition to our detailed catchment analysis, our team employs a more conventional approach by undertaking a heavy minerals test. This allows us to visually identify potential minerals and cross-verify with our primary findings. On client demand, we procure a 2kg sample from key areas, particularly focusing on trap sites and point bars. Here’s what this additional testing offers:

• Particle Size Distribution Assessment: We have the capability to pinpoint mineral content as fine as 2 microns, and subsequently provide an assay report on the total mineral content for particles above a size specified by the client.
• Optimal for Alluvial Mining: Especially beneficial for miners employing gravity-based extraction techniques.
• Clarity on Depositional Size: By discerning the size at which minerals are deposited, we can offer insights into the deposit type and even its proximal distance.
• High accuracy to calculate alluvial grade potential. Using the precision separation process we separate particles that can be captured in an average sluice and tested in the labs to provide accurate results. 

Through this comprehensive approach, we ensure a thorough analysis for our clients, driving their exploration and mining endeavors with greater accuracy.
