Plomosas Project

Yari Minerals – 100% interest in the South Wodgina and Marble Bar Lithium Projects in the Pilbara, home to some of the largest hard rock lithium deposits in the world

Background/ Location

Until 3 April 2023, YAR owned and operated the Plomosas Mine in Mexico. On that date, the mine was sold to Impact Silver Corp. (TSX-V: IPT). The Company retains an interest in that Project through a 12% net profit interest royalty and shares in Impact Silver Corp. which were part of the purchase consideration.


The Plomosas Zinc-Lead-Silver Project covers more than 3,000 hectares in the northern Mexican state of Chihuahua, approximately 350km from Mexico’s border with Texas. Plomosas is in an area with an extensive history of development in base metal operations.

Plomosas Project

The shallow dipping (10°-40°) Plomosas mineralisation has been mined in several stages since 1943 down to approximately 270m below surface via room and pillar stopes using traditional air leg drill and blast techniques. The mineralisation appears to continue at depth and there is more than 6km strike of prospective stratigraphic horizon within the tenement package, providing for excellent additional exploration potential and drill targeting.

Resources and Exploration

YAR believes additional resources at Plomosas may be found:

  • multiple geological layers
  • Down dip of current resources; and
  • Along strike.

Only 600m of 4,000m strike of immediate mine area has been part drilled, with YAR continuing its mapping and drilling activities. There are highly prospective targets defined within immediate mine area, with a prospective sequence that is 4,000m along strike and 900m down dip. Underground access is available for drilling along the 4km of strike. In addition, recent successful mapping has confirmed regional targets on a 7km mineralised sequence, which require follow-up drilling.
