Hathor updates on Midwest NorthEast project
by Jo Black

Exploration Limited has encountered anomalous uranium mineralization during its winter 2007/2008 Midwest NorthEast project drill program. The mineralization occurs in hole MWNE-08-12, the 12th hole of a planned 24-hole program.
Natural gamma emission radiation in drill core was measured in counts per second (cps) using an Exploranium GR-110G gamma-ray scintillometer. Drill core from hole MWNE-08-11 intersected a 20 cm thick zone of elevated radioactivity, ranging from 800 to 1200cps, compared to a background of 100-200 cps.
In drill hole MWNE-08-12, the sandstone column is moderately-fractured throughout the lower portions (depths greater than 130m) with discreet zones of strong- to intense-fracturing. The basal conglomerate is highly-fractured from 220-226m with up to 25% core loss over the interval.
The unconformity occurs at 226m (uncorrected depth), with a 1m thick interval of virtually pure clay lying immediately beneath the unconformity.
The basement rocks occurring immediately beneath the unconformity (uncorrected depths from 227 to 242.5m) show evidence of variable clay alteration to clay replacement, but without any significantly elevated radioactivity with the host rock being a heterogenous mix of pelitic gneiss, graphitic pelitic gneiss, granitic pegmatite and micro-granite.
The first interval of elevated radioactivity measured from drill core is at 242.5m (1000 to 3000 cps) and increased radioactivity continues throughout the drill core until 273.3m. However, the amount of radioactivity over this interval is highly-variable. It can be summarized as a zone of approximately 30 metres of elevated radioactivity (1000-1500 cps) with discreet zones of highly-radioactive (5000 cps to greater than 9999 cps (off-scale)) intervals including 244-245.5m; 252-255.8m; 262.4-264.1m; 265.4-270m; and 271-273.3m. The zone also contains intervals of background radioactivity (200-500cps) from 245.5-252m and 255.8-261m. The geology of the mineralized interval comprises extremely-clay altered to clay replaced graphitic pelitic gneiss, pelitic to psammopelitic gneiss, and leucogranite. Hole MWNE-08-12 ended at 331m.
