..0n the Groves property. My understanding of this VTEM, in reference to the colour purple, is that purple indicates a high degree of magnetic anomaly....The cause of the intense anomaly in the north east section of the survey is unknown at present.... just curious to thoughts, on the black section of this VTEM, located in the north east section. T he historic 500,000 tons, seems pale, to this massive North East trending. Traps7
