Technology Minerals provides Asturmet exploration update

Global Mining Review,

Technology Minerals Plc, the first listed UK company focused on creating a sustainable circular economy for battery metals, has announced initial results from a due diligence lithogeochemical characterisation sampling survey at its 100% owned Aramo Copper-Cobalt-Nickel (Cu-Co-Ni) Project in Asturias, Spain.


  • Due diligence sampling collected in November 2021 has confirmed high grade Cu-Co-Ni mineralisation at the historic Aramo mine on the St Patrick Licence.
  • A total of 79 samples were collected on the licence during the campaign, including 53 samples underground at the Aramo Mine on Level 3 in four historical partially stoped areas.
  • Field programmes are ongoing at the project with a more expansive exploration campaign planned for the St. Patrick Licence in the coming months.

Aims of the sampling

The study involved accessing historical mine workings associated with the Aramo Mine at the accessible upper levels, in particular at the Level 3 elevation (1177 m O.D.) to complete a mineral and alteration characterisation study. The primary zone sampled comprised the St. Pedro Filon, a 30 – 40m wide (partially mined) alteration zone which dips westwards at 35 – 40°. Three stopes within this zone were accessed and a selection of both wall rock and blasted stope piles were sampled.

The characterisation study aimed to collect a broad range of mineralisation and alteration types to better understand the paragenetic model for the deposit and to identify structural controls on the mineralisation. The majority of samples were collected from blasted stope material within the stopes with a selection of wall rock samples in the hanging wall and the footwall of the stoped areas where it was possible.


A total of 79 samples were collected during the campaign and included 53 samples collected at the Aramo Mine on Level 3 in four different stoped areas. A further 17 prospecting samples were also collected at locations on the plateau above the mine. These form part of a broader in-progress programme of ongoing sampling in association with characterisation of both rocks and soils for an ongoing hyperspectral remote sensing study. These results will be compiled and assimilated and reported in due course, along with the results of the remote sensing study. A further seven samples comprised QAQC samples which were submitted along with the geochemical samples.

All samples followed a strict sampling and chain of custody process and were analysed by ALS Laboratories in Loughrea, County Galway, Ireland. Samples were analysed by four-acid ICP-AES analysis.

Further work

Field programmes are ongoing at the project with a full and more expansive exploration programme planned for the St. Patrick Licence in the coming months, which includes geological mapping and sampling, remote sensing analysis and geophysics.

Alex Stanbury, CEO of Technology Minerals, said: “We are pleased the initial results from our sampling survey at the historic Aramo mine within the St Patrick licence has confirmed high grade Copper-Cobalt-Nickel mineralisation. In the coming months, we plan to expand our exploration campaign which will help us continue to gain a better understanding the full potential of the project. The Asturmet Project forms part of our wider strategy to move forward and advance multiple exploration campaigns across our portfolio of mineral resource projects focused on cobalt, copper, nickel, manganese, and lithium.”
