IP Survey Doubles Strike Length of Angel Hill Gold Zone to 2.8km on Houston Lake's West Cedartree Gold Project

SUDBURY, ON--(Marketwire - May 31, 2007) - Houston Lake Mining Inc. (PINKSHEETS: HLKMF) (TSX-V: HLM) (the "Company") is pleased to announce preliminary results from a 30 line-km (18 mile) spectral IP survey conducted by JVX Ltd. of Richmond Hill, Ontario on the Dogpaw Lake ("DP"), Dogpaw West and North Block properties. The three properties form the northern portion of the Company's 100% owned and optioned 1673.6 hectare (4134.5 acre) West Cedartree Gold Project located near Sioux Narrows, Ontario. A preliminary chargeability compilation map that combines results from both the 2006 and the 2007 IP surveys is available at www.houstonlakemining.com. Initial conclusions are as follows:

1. The 2007 IP survey depicts an extremely prominent chargeability anomaly coinciding with the vicinity of the Angel Hill Gold Zone ("AHGZ"). The response is marked by continuous chargeability values exceeding 21.7mV/V. Over 70% of this trend contains values in excess of 30.6mV/V. This anomaly can be traced northward for a distance of 1.4km from the AHGZ bulk sample site and across the DP and Dogpaw West properties. When the findings of the 2006 survey are included the overall strike length of this anomaly spans at least 2.8km (1.7 miles).

2. A strong IP chargeability anomaly trend is associated with the McLennan Zone. This IP response is marked by a series of lenticular chargeability highs that exceed 21.7mV/V. The McLennan IP anomaly can now be traced for over 1200m. This trend appears to gradually merge with that of the AHGZ along both its northern and southern strike extensions. The merging of the AHGZ and McLennan associated trends forms a series of anomalies that are the strongest chargeability responses of the entire 2006-2007 IP coverage.

3. A weak to moderate IP chargeability response trends subparallel to the AHGZ anomaly trend and occurs in the proximity of the Dogpaw No. 1 Vein. This broad anomaly contains chargeability values in excess of 6.8mV/V and contains regions that exceed 21.7mV/V. Several isolated peaks exceed 38.6mV/V along this trend. One of these small peaks coincides with the Dogpaw No. 1 Vein.

4. Deeper penetrating IP surveys were run over L2400N on the McLennan property and probed to depths of over several hundred meters. L2400N passes over the AHGZ stripped area and McLennan Zone on the McLennan property. The pseudo-sections illustrate responses from both zones that appear to be strengthening with depth.

5. Deeper penetrating IP surveys were also run over L1100W spanning the Dogpaw No.1 Vein system. In profile a contour of values exceeding the 13.5mV/V mimic the change in the dip encountered in recent drilling. This chargeability response also appears to be strengthening with depth.

The $82,000 IP program will complete the remaining requirements of the 100% option of the Dogpaw West and Gold Sun properties once the survey is accepted for assessment filing. Houston Lake is earning a 100% interest from Endurance Gold Corp. (TSX-V: EDG) of Vancouver, B.C. subject to a 2.5% NSR.

Results from the 30 line-km 2007 and 15 line-km 2006 IP geophysical surveys will guide upcoming surface exploration programs involving mapping, prospecting, mechanized stripping, detailed mapping and channel sampling. The goal of this work is to generate new drill targets near existing gold resources. About 32 line-km of grid refurbishment has now been completed on the McLennan, Jesse (North) and West Cedartree properties. The re-established grid will act as control for property-scale mapping and prospecting. Down-hole geophysical surveys have begun this week and aim to develop drill targets at depth on the AHGZ and Dogpaw No. 1 Veins. The program of re-examination and re-assaying of the historic core of the Dogpaw No. 1 Vein will be continued in the month ahead.
