Hannan receives 24 concessions at San Martin

2020-01-09 07:17 ET - News Release

Mr. Michael Hudson reports


Hannan Metals Ltd. has received notice from the Geological, Mining and Metallurgical Institute of Peru (Ingemmet) that 24 new mining concessions have been granted at the 100-per-cent-owned San Martin sedimentary copper-silver project in Peru.

San Martin encompass a newly identified, basin-scale high-grade copper-silver system situated along the foreland region of the eastern Andes Mountains in Peru and neighbouring countries. Geologically, these shares similarities with sedimentary copper-silver deposits including the vast Kupferschiefer deposit in Eastern Europe and deposits of the African Copper Belt situated in sub-Saharan Africa, two of the largest copper districts on Earth. Hannan recognized the exceptional potential for large copper-silver deposits in this part of Peru and has aggressively staked a commanding position over 521 square kilometres of prospective geology.


  • A further 24 mining concessions (for a total of 25) have now been granted at the Tabalosos (18 concessions), Sacanche (three) and Gera (four) areas at the San Martin project in Peru. This follows the first granting of a mining concession at the San Martin project in Peru in October, 2019.
  • Hannan has staked a total of 66 mining concessions (25 granted) for 52,100 hectares (521 square kilometres) at San Martin, covering multiple trends within 100 kilometres of combined strike for sedimentary-hosted copper-silver mineralization.
  • The 25 granted mining concessions now cover 20,400 hectares (204 square kilometres), with an additional 41 mining concessions (31,700 hectares, 317 square kilometres) remaining under application.
  • Further mining concessions at Sacanche, Gera and Tabalosos are expected to be granted over the coming months in the order in which they were applied.
  • Under Peruvian mining law, a mining concession provides the holder with exclusive rights to undertake exploration (and mining activities subject to additional permitting) within a predetermined area.
  • The concession provides secure tenure and allows for more advanced social and exploration work programs to be executed including drill permitting.

Michael Hudson, Hannan's chief executive officer, stated: "The sediment-hosted copper-silver San Martin project presents a new basin-scale high-grade copper-silver district in Peru. Further granting of the mining concessions provides secure tenure which will allow for more advanced social and work programs to be executed, including drill permitting. We look forward to further developing trusted relationships with local communities during our upcoming exploration programs which are due to recommence this month."

The San Martin project is located about 30 kilometres northwest of Tarapoto, in the Cordillera Ayu Mayo. Hannan's mining concession applications cover 100 kilometres of combined strike of a prospective sedimentary host horizon. Project access is excellent via a proximal paved highway, while the altitude ranges from 800 metres to 1,600 metres in a region of high rainfall and predominantly forest cover. To date the company has submitted 66 mining concession applications for a total of 52,100 hectares (521 square kilometres) in four different project areas named Tabalosos, Gera, Sacanche and Santa Elena. The 24 granted mining concessions now cover 20,400 hectares (204 square kilometres), with an additional 42 mining concessions (31,700 hectares, 317 square kilometres) remaining under application.

Hannan considers the sediment-hosted copper-silver San Martin project to be a new basin-scale high-grade copper (chalcocite) district. Initial prospecting over the last year identified high-grade mineralization in outcrop and float with associated alteration across a 100-kilometre-by-50-kilometre area. Best results from outcrop within a 20-kilometre trend include three metres at 2.5 per cent copper and 22 grams per tonne silver (LD190517-19) and two m at 5.9 per cent Cu and 66 g/t Ag (TC190536-38). Similar styles of outcrop/boulders have been discovered over 100 kilometres of strike with mineralization observed at multiple stratigraphic levels spatially linked to salt structures that have intruded the sedimentary strata and potentially fed metal-rich fluids responsible for mineralization in the region.

Since the 1970s the area has principally been explored for petroleum, delivering large seismic data sets similar to those being used by Hannan for targeting of zinc in Ireland. Seismically defined basin structures and stratigraphy are now being interpreted in the context of sediment-hosted copper mineralization.

Hannan's geological interpretation for the formation of the sediment-hosted copper and silver at San Martin is mineralization was deposited from low-temperature oxidized saline brines formed from the several-hundred-metre-thick Pareni salt formation. The brines scavenged metals (principally copper plus or minus silver and associated lead and zinc) from the deeper Mitu group red beds and volcaniclastics within in a failed Traissic rift. Circulation of saline fluids across the redox boundary was induced and focused by halokinesis (salt tectonics). 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.

Under the Peruvian General Mining Law, the state retains the ownership of all mineral resources. However, the ownership of minerals is vested in the holder of a mining concession. Mining concession rights are independent from the surface and real estate rights. A mining concession provides the holder with exclusive right to undertake mining activities subject to additional permitting within a determined area. All holders of a mining concession are required to move into production and comply with the applicable minimum annual production thresholds within 10 years from granting. Other permits required to start mining activities in Peru include surface and access rights, environmental certification and permitting, construction, explosive, water resource permits, and disposal of waste materials, among others.

Management of Hannan has 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 in 2018 to 3.8 million tonnes by 2027, averaging 4.7-per-cent annual growth. Sediment-hosted deposits are the world's second-most-important source of copper accounting for approximately 20 per cent of world production.
