Re Henri Anomaly - seems it must have been in the 70's - from WMT's own website:
"Previous Exploration
Previous exploration of the Mtonya area comprised broad scale regional mapping and airborne radiometric and magnetic surveys. These surveys were conducted in the 1970’s using 1kilometer spaced flight lines. The airborne surveys identified many anomalies over the tenement area however ground based field testing was not conducted. Interpretation of the survey data indicates that the anomalous zone extends for approximately 7 kilometers over the tenement area."
