HLM Confirms High-Grade and Continuity of Rare Metals Mineralization with Remaining Holes from Phase I Drilling on the PAK Rare Metals Project, Ontario

SUDBURY, Ontario--(BUSINESS WIRE)-- Houston Lake Mining Inc. (TSX.V: HLM):

Highlights:

  • Diamond Drill Hole (DDH) PL-13-003 intersected 4.22% Li2O over 18 metre (m) from 36 to 54 m;

  • DDH PL-13-005 includes a 19.10 m wide high-grade tantalum zone averaging 236 ppm Ta205from 125 to 144.1 m;

  • The Pakeagama Lake pegmatite, after drilling Phase I, has a 250 m strike length with an estimated width varying from 45 to 125 m assuming sub-vertical orientation of the pegmatite body;

  • The pegmatite remains open in all directions (WNW, ESE and at depth), and;

  • The rare cesium mineral pollucite commonly occurs as rounded-blebs and small masses ranging in size from 10 to 30 mm within the pegmatite's central intermediate zone.


Houston Lake Mining Inc. (TSX.V: HLM), is a mining exploration company that is specialized in rare metals and is actively exploring for lithium (Li), tantalum (Ta), rubidium (Rb) and cesium (Cs) by focusing on its high-grade, 100% owned and optioned 2,816 hectare (6,958 acre) PAK Rare Metals Project in northwestern Ontario, Canada. HLM is pleased to announce the results of remaining five (5) drill holes from the Phase I, six-hole diamond drill program on the Pakeagama Lake pegmatite.

On July 2 2013, HLM reported a 154 m intersection of Li, Ta and Rb mineralization on the first hole drilled this past winter. The additional 5 holes have confirmed continuity of the zones along strike of the intersection and beneath the surface outcrops, and also defined bounding contacts with host rock(s). Table I below summarizes the lithium, cesium, tantalum and rubidium grades for the five drill holes by mineralogical zones for the pegmatite intersections. Also included are the results for DDH PL-13-001 as reported on July 2 complete with the addition of its cesium grades.
