Vancouver, Canada – Hannan Metals Limited (“Hannan” or the “Company”) (TSXV: HAN) (OTCPK: HANNF) announces new sampling results from the northern part of the Sacanche claim application area (8,900 hectares) from the 100% owned San Martin project (38,400 hectares under claim application) in north central Peru (Figure 1).
- Rock chip channel samples from outcrop separated by 5.4 kilometres:
- 2 metres @ 5.9% copper and 66 g/t silver with the wider zone assaying 3 metres @ 4.1 % copper and 45 g/t silver (Figure 2);
- 0.6 metres @ 8.7% copper and 59 g/t silver (Figure 2);
- High-grade grabsamplefrom float assayed 30.1% copper and 595 g/t silver within close proximity to channel samples (Figure 2);
- Multiple mineralized stratigraphic positions and styles have now been defined across the property. Two bituminous quartz sandstones from the Cushabatay Formation returned 2.6% to 2.8% copper and 36 to 50 g/t silver confirming the copper/silver potential of this thick sandstone horizon. Lead-zinc bearing gossans greater than 50m in thickness have been discovered across an 11 kilometre strike;
- The footprint of mineralization at Sacanche has now been defined within a 27 kilometre strike.
Michael Hudson, Hannan’s CEO, states, “In our first exploration field season at Sacanche, sediment-hosted copper-silver mineralization has been discovered across 27 kilometres of strike. Mineralization has been defined within multiple stratigraphic levels. Our initial expectations have been exceeded and the concept of a new copper district is well supported by data. Further prospecting results from south Sacanche and Tabalosos, located 80 kilometres to the north, will follow over the coming months as further results from the field season start to be received.”
Channel samples are considered representative of the in-situ mineralization samples and sample widths quoted approximate the true width of mineralization, while grab samples are selective by nature and are unlikely to represent average grades on the property.
High grade copper mineralization has been discovered in multiple mineralized positions at Sacanche, over a 27 kilometre strike. Two distinct sub-types of the sediment hosted copper style are described throughout Hannan’s claim application areas:
- The first style is hosted by the Cushabatay Formation:
- Mineralization in quartzites with hydrocarbon metal traps, analogous to the giant Udokan copper deposit in Russia and Spar Lake in the USA.This is the first time this style of mineralization has been described in the target area.
- The Cushabatay Formation hosts >50-metre-thick gossanous outcrops with zinc-lead across 11 kilometres of strike, that is interpreted to form distally to copper-silver mineralization.
- The discovery of two bituminous quartz sandstones from the Cushabatay Formation that assayed 2.6% to 2.8% copper and 36 – 50 g/t silver confirms the copper-silver potential of this thick sandstone horizon.
- The second style is hosted by the Sarayaquillo Formation:
- Mineralization is associated with reduced facies within red beds, where petrographic studies show copper sulphides replace both pyrite and organic material. This style is similar to copper mineralization associated with Zechstein Basin in Poland and Central African Copper Belt.
- Copper within the Sarayaquillo Formation has been discovered throughout Hannan’s claim application and extends along an 80 kilometre trend from Tabalosos to Sacanche.
- Evidence for this style is demonstrated by the high grade copper in channel samples reported here at Sacanche (i.e. 2 metres @ 5.9% copper and 66 g/t silver) and by the initial sampling by Hannan in 2018 that discovered four areas of high-grade copper and silver over 15 kilometres of strike within the Tabalosos claim application area. Nineteen grab samples from mineralized float in river beds (>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 27.2 g/t silver.
- The Sarayaquillo Formation/Cushabatay Formation contact is an angular erosional unconformity that is interpreted to relate to salt tectonics (halokinesis).
Hannan’s interpretation is that copper and silver were deposited from low‐temperature oxidised saline brines formed from the several hundred metre thick Pareni Salt Formation. The brines scavenged metals (principally copper ± silver and associated lead and zinc) from the deeper Mitu Group red beds and volcaniclastics which were deposited in a failed Traissic rift. The circulation of saline fluids across the redox boundary was induced and focused by halokinesis. Geological relationships suggest halokinesis was initiated during Jurassic rifting and was active until the early to mid-Cretaceous which coincides with the formation of an Andean foreland basin.
In other news, two claim applications with a total area of 2,000 hectares has been submitted to Ingemmet, covering high grade copper mineralization at Sacanche North.
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.
