Houston Lake Extends Angel Hill Gold Zone at Surface and Completes Drill Program

June 27, 2007: Sudbury, Ontario, Canada - Houston Lake Mining Inc. (TSX.V: HLM, the "Company") is pleased to report that mechanized stripping and washing carried out on one of the four or more gold systems on the Company’s 100% owned and optioned 1673.6 hectare (4134.5 acre) West Cedartree Gold Project located near Sioux Narrows, Ontario, has now extended the Angel Hill Gold Zone (AHGZ) at surface for a total strike length of more than 200m (656ft.). IP surveys in 2006 and recently in 2007, have depicted an extremely prominent chargeability anomaly that can be traced from the AHGZ bulk sample site southward across the McLennan and West Cedartree properties and northward across the Dogpaw and Dogpaw West properties for an overall strike length that spans at least 2.8km (1.7 miles).

Four drill holes totaling 528.2m (1561.7ft.) were drilled in preparation for a down hole spectral IP survey that was carried out last month. Three of these drill holes were completed along the trace of the newly exposed southern extension of the AHGZ. The zone remains open in both directions along strike and to depth. A fourth drill hole tested the McLennan Gold Zone. Geologic mapping and prospecting programs are currently underway, including mechanized stripping, detailed mapping and channel sampling programs. The goal of this work is to generate new drill targets near existing gold resources.

A total of 275 drill core samples including historic core from the 1988 drilling of the Dogpaw No. 1 Vein were shipped for assay analysis late last week. Re-examination of historic core combined with recent drilling and surface work, will guide a drill program planned for late summer/early fall with the objective of completing a NI43-101 resource calculation for the Dogpaw No. 1 Vein.

All drill core samples were shipped to TSL Laboratories of Saskatoon, Saskatchewan and will be analyzed by fire assay utilizing a 50 gram charge. Samples will be assayed with an AA finish and those samples assaying above 3 g/mt Au were retested utilizing a gravimetric finish. Forty-five of the 102 drill core samples will be analyzed utilizing a screen metallic assay method. This methodology provides a higher level of assurance by testing a large quantity of sample (1000g) and by monitoring the size distribution of the gold. The samples will also be re-checked at a second qualified laboratory in keeping with the Company’s standard due diligence procedures.

Independent Consultant Dean R. Cutting, P. Geo., is the Qualified Person for the project under the guidelines of NI 43-101 and has reviewed this press release in its entirety.

Angel Hill Gold Zone (“AHGZ”)

The AHGZ has an estimated inferred mineral resource of 106,400 tonnes grading 2.97 g/mt Au at a cutoff of 2 g/mt (117,286 short tons grading 0.087 oz/st Au at a cutoff of 0.058 oz/st) or 49,700 tonnes grading 4.77 g/mt Au at a cutoff of 4 g/mt (54,785 short tons grading 0.139 oz/st Au at a cutoff of 0.117 oz/st). The inferred mineral resource was determined by systematic channel sampling of a 130m (426ft.) strike length of the AHGZ exposed by stripping and by drilling to a depth of 75m. In 2006 a 1037m (3402ft) drill program was successful in extending the zone to a depth of 100m (328ft).

In spring of 2006 a bulk sample was taken from the AHGZ and processed at a third party mill. A total of 1041.2 tonnes (1147.7 short tons) yielded an average head grade of 5.67 g/mt Au (0.165 oz/st Au). The total contained gold was 5,903.6 grams (189.8 ounces) and 5,490.4 grams (176.5 ounces) of gold was produced at a reported recovery of 93%. The Company received a cash settlement of $131,893.84 and had a net profit of $51,848.12.

Dogpaw No. 1 Vein System

The Dogpaw Lake Property “DPL” has an extensive exploration history dating back to the 1940’s. Four main gold zones and ten documented gold occurrences have been discovered thus far on the property. An historic resource estimate of 53,741 metric tonnes grading 15.43 g/mt Au (59,240 short tons grading 0.45 oz/st Au) remains after the extraction of a 454 metric tonne (500 short ton) bulk sample grading 8.23 g/mt Au (0.24 oz/st Au) from the Dogpaw No. 1 Vein.

A winter 2561m (8400ft) delineation drilling program targeted the historic gold resource of the Dogpaw No. 1 Vein. Fourteen of 17 drill holes intersected grades of 3.31 g/mt Au (0.097 oz/st Au) or higher and established the continuity of the gold mineralization to the maximum depth tested of approximately 210m (689ft.). The vein system remains open to depth and along strike. The best result of the drill program was received from drill hole DP-2007-042 which yielded a core length intersection grading 29.90 g/mt Au over 7.50m (0.872 oz/st Au over 24.60 ft).

The Company’s exploration team have located, recovered and racked approximately 6,656m (21,831ft) of drill core from two previous drill programs. Only the portion of this drill core testing the Dogpaw No. 1 Vein is currently being re-logged and audited as part of the resource evaluation. Thirteen holes from a 2,333m (7,651ft) 19 hole 1988 drill program are currently being logged and sampled.

The tonnages, grades, assays and other technical data are taken from historical records prior to the implementation of NI 43-101. While the data are believed to have been acquired, processed and disclosed by persons believed to be technically competent, it is unverifiable at present. The data source for the DPL property is largely provided by assessment records and prior work conducted by Houston Lake. A qualified person as defined under NI 43-101 has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. Houston Lake is not treating the historical estimates as current mineral resources or mineral reserves as defined in NI 43-101 and the historical estimate should not be relied upon.
