STRONG GOLD ANOMALIES: Widgety prospect
Background
-
In July 2015, Marmota Energy Limited (ASX: MEU) (“Marmota”) commenced an aggressive gold exploration program across its prime tenement holdings around the Challenger gold mine.
-
Marmota has adopted the same calcrete sampling methodology that was used to find Challenger itself.
Key Points
-
Calcrete sampling at the Widgety prospect (50km SE of the Challenger gold mine) has returned strong gold anomalous assay results.
-
96 sample locations at Widgety have returned anomalous gold-incalcrete readings ≥ 20 ppb (out of 331 samples taken at Widgety).
-
For comparison, a gold-in-calcrete result of 20ppb is:
-
better than 98.4% of all calcrete sampling data recorded in the South Australian Government database of 192,677 samples
-
RC drilling to commence at Widgety prospect in November 2015
WIDGETY PROSPECT
Existing data at Widgety highlighted a gold-in-calcrete geochemical anomaly, trending in the same north-east direction as other geochemical anomalies within the region. Widgety was highlighted as one of Marmota’s gold target areas in the Gawler Craton [see ASX:MEU announcement: 6 July 2015]. Calcrete sampling via auger drilling was carried out at the Widgety prospect on a fine 50m x 50m grid pattern, in-filling existing anomalous data.
Assay results indicate the gold anomaly is coherent, with consistent results up to 60ppb gold (10ppb is considered anomalous) covering an area 1700m x 1000m (see Figures 1 and 2). The Widgety prospect also has associated aeromagnetic anomalies (see Figure 3).

Marmota’s Chairman, Dr Colin Rose, said:
- “ Marmota is searching for Challenger-style systems – Challenger itself has a small footprint, with narrow shoots. The calcrete sampling program at Widgety has identified not just one, but several anomalous clusters, each around 250m wide. Detailed ground magnetometry and gravity will be used to further refine targets in advance of RC drilling in November. ”

Location of Widgety Prospect
The Widgety prospect is located about 50km south-east of the Challenger gold mine, in the ‘neck’ of Marmota’s Muckanippie Tenement, in the Woomera Prohibited Defence Area, in the highly prospective and significantly underexplored Gawler Craton.

Calcrete Sampling
Calcrete sampling is a useful exploration tool utilised to detect potential gold mineralisation hosted in basement rocks beneath the surface. It is the very method that was used to discover the Challenger Gold Mine. Calcrete is a calcium rich sedimentary rock type that typically forms just below the surface within the project region. It is typically formed by calcium carbonate precipitated from solution and re-deposited through the agency of infiltrating waters, or deposited by the escape of carbon dioxide from groundwater. It occurs in a variety of forms, where it can form a duricrust, can be pisolitic, nodular, pebbly, slabby or massive and powdery. It is a proven accumulator of gold and other metals in the Gawler Craton. Calcrete samples are obtained by auger drilling close to the surface.

Empirical Distribution of ‘Gold-in-Calcrete’ The Gawler Craton data set The South Australian Government maintains and collects a huge database of all registered calcrete samples, currently totaling 192,677 different calcrete samples taken in the Gawler Craton area. The database includes both random 1-mile grid data and massive infill data. To enable meaningful evaluation, Marmota has conducted a basic statistical analysis on both:
- A: ‘Pure random sampling’ data set Size: 3,691 calcrete samples [ based on pure 1 mile grid data –– no in-fill ]
For this pure random sampling dataset, a gold-in-calcrete result of:
20 ppb is better than 99.8% of pure random data
- B: Massive South Australia Government database The Gawler Craton data set Size: 192,677 calcrete samples [ based on: random data AND in-fill sampling ]
For the complete data set (including in-fill sampling), a gold-in-calcrete result of:
20 ppb Au is better than 98.4% of all data collected 25 ppb Au is better than 98.9% of all data collected 30 ppb Au is better than 99.2% of all data collected
10 ppb gold-in-calcrete at a specified sample spacing is typically considered to be anomalous.
