Nortec Minerals Corp. provides Tomboko Exploration Results Update
-
- 9 m at 2.74 g/t gold from 32 m, including 3.57 m at 3.91 g/t from 36 m;
- 7 m at 3.57 g/t gold from 43 m, including one m at 17.1 g/t from 45 m.
Highlights of the latest results are as follows:
-
- Trenching results at Tom 1 to the west of TBDD003 include 24m@3.66g/t incl. 4m@10g/t from 18m;
- Chip sample results at Priorty 1 Tom 1 target of 0.02 to 35.6 g/Au in float oxidized sedimentary rocks with quartz vein (stock work), limonite, iron and 19.8 g/t Au in sub-outcrop quartz vein fractured N050 sub-vertical (G2); and,
- The first 7 RAB drillhole results returned values from trace to 2m@3.01g/t Au.
The results to date indicate a significant potential for hosting a major gold deposit. Further exploration of Tom 1, Tom 2 and Tom 3 (Figure 2) will consist of drilling, surface sampling and trenching. The company will release conclusions and recommendations with detailed structural interpretations on all 3 targets when all the information has been compiled and reviewed.
Dr. Serigne Dieng, Ph.D., AusIMM, will be reviewing, compiling and interpreting all the diamond core, RAB and trench sampling data and results. Dr. Dieng is a registered qualified professional geoscientist in accordance with NI 43-101 and JORC standards. He has 20 years' experience in geological and structural interpretation, modelling and target generation in West Africa. Dr. Dieng received his Ph.D. in Structural Geology, Exploration Geochemistry and Ore Deposit Genesis from Queens University, Kingston, Ontario (see News Release June 6, 2018).
Mohan Vulimiri, Chairman and CEO said: "Nortec is very pleased with the way the Tomboko Project is developing and in particular the results of the trenching program. The Company is accelerating our development of Tomboko with Dr. Serigne Dieng joining the team and we look forward to strong news flow in the coming months"
Latest Partial Results from Diamond Core Drilling, RAB Drilling and Trench Sampling (Tables 1, 2 & 3)
Follow-up diamond drilling to trace the Priority 1 Target, Tom 1 North Zone intersected in drill holes TBDD003 and TBDD007 to the south-west returned minor gold values. In view of these results to better understand the geochemical signatures, the structural trends and controls, RAB drilling program and trench sampling was initiated on the Priority 1, 2 and 3 targets, Tom 1 North, Tom 1 South, Tom 2 and Tom 3 Zones (Figures 2, 3 & 4).
One bulldozer trench was dug in the East-West direction to understand the geology and structural control and was channel sampled systematically near drill hole TBDD003. The trench samples returned highly significant values, shown in the following Table.

The drill core was sawed in half and the chip samples were split in half. The samples were analysed by SGS Labs, an accredited laboratory in Bamako, Mali. A duplicate, a blank and a standard were inserted every 10th sample for quality control. Samples are processed by Fire Assay with A.A. finish under the SGS FAA505 protocol.
RAB samples were logged in detail and split with a splitter until the weight of the sample is 2 kg to 3 kg. The samples were then analysed by SGS Labs.
