Houston Lake Mining Inc. (TSX.V: HLM), is a mining exploration company which is actively exploring for rare metals lithium, tantalum, rubidium and cesium by currently advancing its 100% owned and optioned PAK Rare Metals Project in northwestern Ontario, Canada. HLM is pleased to announce the addition of 500 metres to the originally planned 1,000m announced on the February 18, 2014 press release. The phase II diamond drill program is a follow-up to the Canadian National Instrument (N.I.) 43-101 maiden mineral resource estimate that was filed by the Company in December 2013, see news release dated December 4th, 2013. The drill program focused on the recommendations from the report and is designed to expand and infill the current resource on the project by testing along strike and to infill on selected sections of the deposit with a particular focus on the higher grade Upper Intermediate Zone (UIZ) of the deposit.

The drill program consisted of 1,500m in seven holes targeting the Pakeagama Lake pegmatite. The objectives of the program are (1) to upgrade some of the resource to an indicated level, specifically some of the 1.17 million tonnes grading 3.44% Li2O in the technical/ceramic grade spodumene lithium zone (UIZ) with low inherent iron, and (2) to expand the resource which currently has a 265m strike length with an estimated width varying from 45 to 125m with a sub-vertical orientation. Samples are currently being processed and will be sent to the laboratory shortly. The assay results of all drillholes will be released once analyses have been reviewed and are subject to QA-QC review.

About the PAK Rare Metals ProjectThe PAK Rare Metals Project lies close to the boundary between two geological sub-provinces in northwestern Ontario. The deposit is a LCT (lithium, cesium, tantalum) classified pegmatite. These rare types of deposits have been the principal source of hard rock lithium, tantalum, rubidium and cesium ores mined in the world.

HLM is actively developing its 100% owned and optioned project which contains the Pakeagama Lake pegmatite. The deposit has a current new NI-43.101 compliant Inferred Resource of 6.89 million tonnes of 1.86% Li2O Eq. The pegmatite uniquely hosts 1.17 million tonnes grading 3.44% Li2O in a technical/ceramic grade spodumene lithium zone (UIZ) with low inherent iron content. The Pakeagama Lake pegmatite has a 265m strike length with an estimated width varying from 45 to 125m with a sub-vertical orientation of the pegmatite. The resource remains open to depth and along strike to the northwest and southeast.

About Houston Lake Mining Inc.HLM’s goal is to become a fully integrated lithium and tantalum producer by targeting the growth as a result of the shift towards electric/hybrid vehicles and high quality consumer electronics through the development of the PAK Rare Metals Project in Ontario, Canada. Combined, HLM’s Board of Directors and Management have over 255 years of exploration and mining experience in order to facilitate the Company’s goal of becoming a raw material supplier of the elements required for the pursuit of sustainable energy, and other applications in high-tech electronics and metal alloys.

HLM has a total of 80,215,695 common shares issued and outstanding. For additional information, please visit www.houstonlakemining.com.
