Highfield Resources intersects potash mineralisation at two permit areas

Highfield Resources has completed exploration drill holes at its Vipasca and Sierra del Perdón permit areas in Spain.


  • Recently completed drill-holes at Ampliación de Adiós in the Sierra del Perdón (SdP) permit area and Vipasca permit area have all intersected potash mineralisation at encouraging grades and mineable depths.
  • Drill-hole V18-03 has confirmed the continuity of the Vipasca ore deposit which remains open towards the west. Specifically, V18-03 intersected a total of 30.2 m of potash mineralisation including:
  • - 1.5 m at an average grade of 11.98% K2O from 1022 m;
    - 1.8 m at an average grade of 11.29% K2O from 1060 m; and
    - 1.5 m at an average grade of 12.79% K2O from 1070 m.
  • Drill-hole V18-05 has confirmed the extension and continuity of the potash mineralisation between the Muga project and Vipasca thereby linking these two projects.
  • Drill-hole AA-01 (Ampliación de Adiós investigation permit) has confirmed the presence of potash mineralisation at shallow depths and the extension of the mineralisation to the south of the former potash operation Potasas de Subiza. This is encouraging in terms of the exploration potential of the southern area of the Sierra del Perdón project. Specifically, AA-01 intersected a total of 9 m of potash mineralisation including:
  • - 1.2 m at an average grade of 9.05% K2O from 390.8 m; and
    - 1.5 m at an average grade of 14.50% K2O from 394.1 m.

Highfield Resources Chairman and interim CEO, Richard Crookes said: “The positive results specifically at V18-03 further reinforce the importance of Vipasca to the Muga project. Importantly, these results provide Highfield with an increased dataset to evaluate and develop a single resource across Vipasca and Muga.”

The Vipasca permit area is located adjacent to the Muga project, covers approximately 27 km2 and is highly prospective for economic potash mineralisation. The ongoing drill programme at Vipasca is focused on the deeper, higher grade, P1 and P2 potash horizons.

The main aim of the current drilling campaign is to confirm and delineate the Muga deposit in its westernmost area. Notably, the results obtained to date have confirmed that the overall geological setting at Vipasca and the lithologies, seams and other geological features are similar to those previously defined by drilling at Muga.

Highfield´s SdP tenement area is located south east of Pamplona and covers an area of approximately 120 km2. SdP is a brownfield target which previously hosted two potash mines, which operated from the 1960s until the late 1990s and produced nearly 500 000 tpy of K60 muriate of potash. The company is targeting potential for potash exploitation in the other unmined and under explored, areas in the SdP tenement area.
