The Mactush property hosts eleven (11) documented BC MINFILE occurrences, including two prospects (one developed), plus 31 other mineral occurrences identified and located previously.1
The Property is comprised of 8 contiguous mineral claims covering about 274.78 hectares (678.99 acres) situated in the Alberni Mining Division centered approximately 10 kilometres southwest of the town of Port Alberni.1
The Mactush property is mostly underlain by Karmutsen mafic volcanics and Island felsic intrusives, with local inliers of possible Quatsino limestone and/or Parson Bay and Bonanza sediments and volcanics. These rocks are variably block-faulted and folded and represent ideal settings for clustered copper-gold-silver-molybdenum porphyry, skarn and epithermal vein deposits.
True width estimated to be 70-90% of drilled interval.
Exploration efforts throughout the property area have been detailed in assessment work reports as far back as 1968 and includes extensive prospecting, soil sampling, silt sampling, rock sampling, limited trenching, various geophysical campaigns, as well as limited percussion and diamond drilling campaigns.
A work summary is presented in the adjacent table.
Property-wide gold, silver, and copper anomaly maps were created by performing Jenks’ optimizations on all relevant and separate populations of assay data spanning multiple sample types, including rock / chip /outcrop samples, soil samples, and moss mat / silt samples.
Jenks optimization, also known as the Jenks natural breaks classification method, is a data clustering technique used to determine the best arrangement of values into different classes by minimizing variance within each class and maximizing variance between classes. This method is particularly useful in geographic and geological data analysis as it effectively identifies natural groupings within the data. By partitioning the data into a predefined number of classes (in this case, five), Jenks optimization reduces the sum of squared deviations from the class means, thereby highlighting significant patterns and anomalies. For this property, the author applied the Jenks method to classify precious metal assay values from soil, silt, and rock samples from multiple exploration campaigns into five distinct classes, ensuring that each class represents a meaningful and statistically distinct grouping of concentrations. This approach aids in identifying areas with the highest exploration potential based on naturally occurring breaks in the dataset.
In 2009 the Mactush property was expanded to cover the Cous Creek copper skarn occurrence and the remaining portion of the Cous target area.
In early 2012, a remote sensing analysis including hyper spectral analysis, mineral alteration mapping and fused radar data analyses yielded six target areas on the property as follows: Cous/MC, Rex, West, South, Mactush Veins and Dauntless. These targets generally match the anomaly clusters from the 2005 airborne geophysical survey.
In 2013, a geophysical interpretation and inversion of the 2005 airborne magnetic survey data identified five areas on the Property which warrant detailed 3D Inversion Modeling as follows: Cous, Rex, Fred, Canal and Dauntless. Detailed inversions provide very useful insights into the sub-surface characteristics of these known mineralized areas.
