All Anomaly G samples consist of 1 metre continuous bedrock chips. Bedrock exposure ranged from 25% to 80% in the 15 trenches (averaging 58%), due to deep overburden. Geologists often interpret sections of deep overburden as corresponding to zones of recessive, altered and possibly mineralized areas. Bedrock consisted of weakly to strongly bleached, oxidized and silicified dacite, with the exception of Trench 07-12, 80 metres to the south of soil channel trench 2.
Trench 07-07 was 38 metres long, cutting across the central section of soil grid anomaly “G” between the two soil channel trenches. 70% of the trench reached bedrock. Gold values in the trench ranged from 9 ppb to 1.38 grams per tonne. Within the trench a 6 metre continuous interval averaged 0.919 grams per tonne gold. In addition, a one metre interval reported 1.02 grams per tonne.
Trench 07-08, was 25 metres long, lying immediately south of the eastern section of soil channel trench 2 on gold-in-soil anomaly “G”. Approximately 75% of the trench length reached bedrock. Gold values in trench 07-08 ranged from 11 ppb to 761 ppb.
Trench 07-08A, the western continuation of Trench 07-08 was 5 metres long. A four metre continuous interval averaged 193 ppb Au. Eighty percent of the trench exposed bedrock.
Trench 07-09 was 27 metres long and lies immediate north of eastern half soil channel trench 1. Bedrock was exposed in 67% of this trench. Gold values ranged from 2 to 379 ppb Au, with a continuous 3 metre interval averaging 243 ppb Au.
Trench 07-09A was 37 metres long and lies immediately north of the western half of soil channel trench 1 and immediately west of Trench 07-09. Only 53% of the trench reached bedrock. Gold values ranged from 1 to 823 ppb Au, with a continuous 5 metre interval (open in both directions) averaging 512 ppb Au.
Trench 07-10 was 67 metres long, lying 10 metres to the south of Soil Trench 2. Only 52% of the trench exposed bedrock. Gold values in the trench ranged from 1 to 578 parts per billion (ppb) Au. A continuous 5 metre interval averaged 337 ppb and a second continuous 4 metre interval (open to the west) averaged 270 ppb Au.
Gold values in the remaining Anomaly G trenches ranged from 1 to 487 ppb Au. Trench 07-12, 50 metres long, exposed a darker grey green dacite porphyry showing zones of quartz stringers and some silicification. A 1 metre continuous chip assayed 487 ppb Au.
