Highfield Resources: Sierra Del Perdon Potash Project Update
November 27, 2013 (Source: Highfield Resources) — Highlights:
- Five confirmatory drill holes completed
- SDP004 intersected a 4.80m sylvinite seam of 15.9% K2O (25.2% KCl)
- SDP005 intersected a 1.80m sylvinite seam of 15.5% K2O (24.5% KCl)
- SDP006 intersected a 1.90m carnallite seam of 13.5% K2O (21.4% KCl)
- Work commenced on JORC code Mineral Resource estimate
- Development strategy to be confirmed and released in January 2014
Spanish potash developer Highfield Resources is pleased to provide an update on its 100% owned Sierra del Perdón potash project located in Northern Spain. The project covers an area of over 100km2 and contains two former operating mines that produced close to 10 million tonnes of potash between 1972 and 1997.1
CONFIRMATORY DRILLING CAMPAIGN RESULTS
Highfield has completed five drill holes as part of its confirmatory drilling campaign (SDP004, SDP005, SDP006, SDP009 and SDP013). Each drill hole was designed to test an element of the project including the extent of potash mineralisation, thickness of sylvinite and carnallite seams and potassium grades. The SDP002 drill hole was not completed when circulation was lost after intersecting a 6.0m potash seam. It was replaced by SDP006.
Holes SDP004, SDP005, SDP006 and SDP013 each intersected a thick carnallite seam confirming historical information with respect to the thickness of carnallite above some halite interbedding with sylvinite. The assay results of SDP004 showed a potash intersect containing an upper interbedded carnallite seam of around 9.0m and lower interbedded sylvinite seam of 5.0m (Table 1). The drill hole intersected 7.5m of continuous mineralisation at 14.9% K2O (23.6% KCl) comprising the lower carnallite seam and underlying sylvinite seam.
Drill hole SDP009 was aimed at testing the extent of potassium within the evaporite. The hole was drilled down to a depth of 94.5m at which time it was determined potassium mineralisation did not extend into the shallow Eastern section of the evaporite.
Assay results for SDP005 show a potash intersect commencing at a depth to surface of 415m and finishing at 435m (Table 2). Within this intersect is a 5.1m a lower carnallite seam at an average grade of 11.0% K2O (17.4% KCl) and a 1.8m sylvinite seam of 15.5% K2O (24.5% KCl). Above this sylvinite seam was a void of 2.7m. Historical mine records suggest this area was mined for its sylvinite content.

Assay results for SDP006 show a potash intersect commencing at a depth to surface of 201m and finishing at 207.5m (Table 3). Within this intersect is a 1.9m lower carnallite seam at an average grade of 13.5% K2O (21.4% KCl). Historical mining records indicate the sylvinite seam was fully mined.
Drill hole SDP013 has recently been completed. A 10m potash seam was intersected at a depth from surface of 510m. Samples have been prepared and sent for chemical testing.
The Company is awaiting the assay results from drill hole SdP013 before confirming its development strategy for the Sierra del Perdón project. This information is expected to be received and in turn released in the January Quarter of 2014 at which time the Company expects to release a JORC code Mineral Resource estimate.
The Company´s focus remains on developing its 100% owned Spanish potash projects. The Company is presently developing both its Javier and Sierra del Perdón potash projects where significant in place infrastructure and shallow sylvinite mineralisation appear ideal for mineral extraction via declines. These advantages are likely to support relatively low capex initial mines.
