The Tomboko Permit totals more than 75 square kilometres and is located immediately west of, and is surrounded by Anglo-Ashanti’s SAG multi-million ounce gold mine and related land holdings. Extensive bedrock (rock geochemical sampling), soil, termite mound and pit sampling (over 10,000 samples) plus detailed geological mapping delineated three targets for immediate follow up drilling, Tom-1, Tom-2 and Tom-3.
Termite mound sampling resulted in high gold values of 7.1 g/t, 3.5 g/t, 2.7 g/t 2.3 g/t, 2.2 g/t, 1.8 g/t, 1.7 g/t, 1.6 g/t, 1.5 g/t, 1.4 g/t, 1.2 g/t and 1.1 g/t. Geochemical soil anomalies were delineated over several kilometres on all three targets that were over 100 ppb gold and some with greater than 600 ppb gold. Rock geochemical bedrock sampling, consisting of 65 samples, on the Tom-1 Zone-North prospect returned high grade gold values of 84.6 g/t, 35.8 g/t, 13.9 g/t, 5.8 g/t, 4.7 g/t and 2.5 g/t. The objective of the rock geochemical sampling was to test various rock types that are associated with the NW-trending termite gold anomalies. Over 9,779 termite mound samples and 212 bedrock samples were collected and analysed for gold.
The gold mineralization on the Tom-1 and Tom-2 targets appears to be hosted in highly altered, sheared, brecciated sandstone and volcanic rocks of the early Paleoproterozoic age Siguiri Basin. The SAG Mine is also hosted in the same age rocks. The TOM 3 Prospect is hosted in quartz porphyry intrusive rocks. The mode of occurrence of the gold mineralization is similar to the Koulékoun deposit owned by Avocet Mining, located 120 kilometres to the south; a resource of indicated 31.5 mtonnes at 1.38g/t Au (1.4 million ounces) and inferred 22.8 mtonnes of 1.22g/t Au (892,200 ounces), (re: http://www.avocetmining.com/guinea).
“Nortec undertook a first pass Diamond and RAB drill programs on these three Prospects in September 2017. At TOM-1 North Target gold mineralization was intercepted (email@example.com/t(including firstname.lastname@example.org/t) and email@example.com/t) over the NW-striking sinistral brittle-ductile fracture systems. At TOM-2, RAB drilling over the NE-striking brittle-ductile dextral strike-slip fault systems intercepted firstname.lastname@example.org/t (including email@example.com/t) and firstname.lastname@example.org/t.
Detailed geological mapping confirmed a strike length of 2.5 km and a true width of 24m at 3.6g/T Au on the main TOM-1 North Target. High gold grade in grab samples from rock outcrops north of the main showing include 34.8g/t, 13.1g/t, 12.8g/t, 8.87g/t, 6.8g/t, 6.2g/t, 4.1g/t, 3.8g/t and 3.8g/t. Termite mound samples range from trace to 3,159 ppb or 3.16g/T Au.”
