Vancouver, Canada – Hannan Metals Limited (“Hannan” or the “Company”) (TSXV: HAN) (OTCPK: HANNF) announces first field results from the Sacanche area of the San Martin sediment-hosted copper-silver project in north-central Peru. Sacanche (Figure 1) is located 80 kilometres south of Tabalosos, where Hannan has previously sampled high grade copper-silver mineralization.
Key points:
- Prospecting at Sacanche over the past month discovered multiple stratigraphic levels of copper and zinc-lead mineralization in outcrop and boulders over 7 kilometres of strike;
- Detailed mapping and sampling of copper-mineralized outcrops was completed over 1 kilometre of strike, with highlight rock chip panel sampling results including (Figures 2, 3 and 5):
- 3 metres @ 2.5% copper (“Cu”) and 22g/t silver (“Ag”);
- Two areas of high-grade copper and silver have been found over 3.5 kilometres within creeks at the Sacanche claim application area. Ten grab samples from mineralized float in riverbeds (>0.1% copper) ranged in grade from 0.4% to 5.0% copper and 4 g/t to 33 g/t silver and averaged 2.7% copper and 17 g/t silver;
- A >50-metre-wide gossanous zinc-lead outcrop that was discovered with over 50 metres strike length. Four grab samples from different parts of the outcrop ranged in grade from 0.1% to 2.4% zinc (“Zn”) and 0.2% to 1.0% lead (“Pb”) and averaged 1.0% zinc and 0.7% lead (Figures 2, 4 and 7);
- An exploration team will be stationed at the San Martin project until late September exploring the vast land holding.
Michael Hudson, Hannan’s CEO, states, “In our first month of prospecting at Sacanche, we have discovered a new zone of sediment hosted copper mineralization over 7 kilometres of strike. We are encouraged by the first discovery of high-grade copper in outcrop and thick (>50 metre wide) lead-zinc gossans on the project. This is an important proof of concept in defining potential for a large high-grade mineral system. Importantly, we interpret a zonation between lead-zinc and copper rich areas and observe mineralization formed at multiple stratigraphic levels. Field work continues and results will follow.”
During May and early June 2019, Hannan’s exploration team prospected 8 kilometres of the 24-kilometre-long Sacanche claim application. Sixty-seven rock samples from outcrops and boulders and 37 stream sediment samples have been analysed and are reported here. Copper mineralization and related zinc-lead gossans in outcrop and boulders have been mapped across greater than 7 kilometres of strike at Sacanche.
Data from field mapping is being interpreted, however distinctive characteristics have emerged including:
- Mineralization forms at multiple levels within a 1,000-metre-thick stratigraphic package;
- Mineralization is spatially linked to salt structures, and
- Both copper-silver and zinc-lead are interpreted to relate to one mineralizing system, where zinc-lead deposited distal to copper mineralization, implying potential for additional copper mineralization hosted by grey sandstones of the upper Grupo Oriente.
Highlights from channel sampling of outcrops include 3 metres @ 2.5% copper (“Cu”) and 22 g/t silver (“Ag) including 0.5 metres @ 4.4 % copper (“Cu”) and 61 g/t silver (“Ag”) at a 1% copper lower cut. At a lower cut-off, the zone assayed 5.0 metres @ 1.7% Cu and 14 g/t Ag. A second area 60 metres away assayed 1.5 metres @ 1.0 % Cu and 52 g/tAg, however only partial sampling was possible and the width of mineralization remains unknown.
A >50 metre wide gossanous zinc-lead outcrop was discovered with over 50 metres strike. Four grab samples from different parts of the outcrop ranged in grade from 0.1% to 2.4% zinc (“Zn”) and 0.2% to 1.0% lead (“Pb”) and averaged 1.0% zinc and 0.7% lead from (Figures 2, 4 and 7). Field indications suggest that the gossanous zone may continue intermittently over 5 kilometres of strike.
While most copper mineralized boulders located during creek prospecting can be correlated to the stratiform copper mineralization style discovered in outcrop, mineralized boulders in the south of the project include diverse lithologies suggesting copper targets exist which have not yet been located in outcrop (Figures 2, 3 and 6). Creek sampling by Hannan on the Sacanche claim application outlined 2 areas of high-grade copper and silver over 3.5 kilometres of strike. Ten grab samples from mineralized float in riverbeds (>0.1% copper) ranged in grade from 0.4% to 5.0% copper and 4 g/t to 33 g/t silver with an average grade of 2.7% copper and 17 g/t silver. These results are of similar tenor to those achieved by Hannan in creeks some 80 kilometres to the north in the Tabalosos claim area where 19 grab samples from mineralized float (>0.1% copper) ranged in grade from 0.1% to 8.3% copper and 0.2 g/t silver to 109 g/t silver with an average grade of 2.8% copper and 27 g/t silver.
Channel samples are considered representative of the in-situ mineralization samples and sample widths quoted approximate the true width of mineralization, rock chip panel sampling is considered moderately representative of in-situ mineralization while grab samples are selective by nature and are unlikely to represent average grades on the property.
Management of Hannan have significant prior experience in Peru, which is the world’s second largest copper producer. The country's copper output is forecast to increase from 2.5 million tonnes (“Mt”) in 2018 to 3.8Mt by 2027, averaging 4.7% annual growth. Sediment-hosted deposits are the world’s second-most important source of copper accounting for approximately 20% of world production.
