Houston Lake Intersects 7.35 Meters Grading 6.21 g/mt Au in Drilling at West Cedartree Gold Project

May 22, 2007: Sudbury, Ontario, Canada - Houston Lake Mining Inc. (TSX.V: HLM, the "Company") is pleased to announce assay results received from seven drill holes of the 17 hole, 2561m (8400ft) 2007 delineation drilling program on the Dogpaw Lake Property (“DP”). The DP forms part of the Company’s 100% owned and optioned 1673.6 hectare (4134.5 acre) West Cedartree Gold Project located near Sioux Narrows, Ontario. Six of the seven reported drill holes intersected values in excess of 3 g/mt Au (0.087 oz/st Au). Drill hole DP-2007-55 was one of the deepest holes of the entire program and intersected 7.35m grading 6.21 g/mt Au (23.94ft. of 0.185 oz/st Au) including 1.12m grading 26.82 g/mt Au (3.67ft. of 0.782 oz/st Au).

A 17 drill hole, 2561m (8400ft) delineation drilling program commenced on February 15, 2007. The aim of the program was to initiate the upgrading of the historic resource on the Dogpaw No. 1 Vein to modern NI43-101 standards by providing systematic coverage of the gold mineralization. Fourteen of 17 drill holes intersected grades of 3.31 g/mt Au (0.97 oz/st Au) or higher and established the continuity of the gold mineralization to the maximum depth tested of approximately 210m (689ft.). 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 Dogpaw No. 1 Vein is presumed to initially dip to Grid North at 70 degrees and then steepen to about 80 degrees at an approximate depth of 100m (328ft.). True widths of drill holes DP-07-52 to DP-07-58 would therefore be approximately: 73% of the stated core lengths of the drill holes with 53° dips, 69% for holes with 56° dips, 62% for holes with 62° dips, 56% for holes with 66° dips and 47% for drill holes with 72° dips.

Drill core samples were shipped to TSL Laboratories of Saskatoon, Saskatchewan and analyzed by fire assay utilizing a 50 gram charge. All samples were assayed with an AA finish. Those samples assaying above 3 g/mt Au were retested utilizing a gravimetric finish. Results have now been received from a total of 264 samples.  Results varied from trace to 435.60 g/mt Au (12.705 oz/st Au). An analysis of results from the first batch of 57 verification samples taken from a 1997 drilling program suggests the presence of a nugget effect. As a precaution all samples will be re-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. Samples from both the 2007 and 1997 drill programs will also be re-checked at a second qualified laboratory in keeping with the Company’s standard due diligence procedures.

The Company’s exploration team have located, recovered and racked approximately 6,656m (21,831ft) of drill core from two previous drill programs. Houston Lake has completed the initial testing of that portion of a 41 hole, 4,323m (14,180ft.) 1997 drill program investigating the Dogpaw No. 1 Vein as part of the resource evaluation. A preliminary examination of this drill core suggests that previous sampling of mineralized sections was incomplete and that more sampling will be required to properly document the vein system. Additionally, a 19 hole, 2333m (7652ft.) drill program conducted in 1988 will also be re-logged and re-sampled as part of the ongoing resource evaluation.

Technical crews were mobilized to the property two weeks ago. Over 70 line-km of grid refurbishment is now underway. The re-established grid will act as control for property-scale mapping and prospecting. Mechanized trenching, stripping and washing of a 60m southerly strike extension of the AHGZ has now been completed, detailed mapping of the strike extension is in progress and channel sampling is expected to begin this week. The program of re-examination and re-assaying of the historic core of the Dogpaw No. 1 Vein will be continued over the month ahead. Down-hole geophysical surveys are being scheduled to develop drill targets at depth on the AHGZ and Dogpaw No. 1 Veins.

Results from the 30 line-km 2007 IP geophysical survey covering the DP, Dogpaw West and North Block properties are expected to be received this week. The geophysical program aims to trace strike extensions of the Angel Hill and McLennan gold zones northward onto the DP and Dogpaw West properties and to identify new IP targets for follow up work. The IP survey results will guide 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.

Houston Lake has completed the cash payment of $100,000 and issued 200,000 common shares required to meet the requirements of the Dubenski Option Agreement after receiving regulatory approval. Road access into the property has been upgraded and fencing around the old mine shaft has been re-established.

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.

About the West Cedartree Gold Project

The West Cedartree Gold Project is located near Kenora, Ontario. Four key property acquisitions in the last year including the Dubenski, Dogpaw Lake, Dogpaw West and Gold Sun properties, has increased the land position to 1673.6 hectare (4134.5 acre) covering a 6km (3.6 mile) strike length of the key geology. The project contains 2 high-grade gold-bearing zones, the historic McLennan (“MGZ”) and the recently discovered Angel Hill Gold Zones (“AHGZ”) as well as multiple high grade vein systems contained within the Dogpaw Lake (“DP”) and Dubenski properties.

In April 2006, a 1012 tonne bulk sample (grading 5.67 g/mt Au) was taken from surface on the AHGZ and processed at a third party mill.  A total of 5,490.4 grams (176.5 ounces) was produced with a reported recovery of 93%.  The bulk sample generated a cash settlement of $131,894 and a net profit of $51,848. The AHGZ has an inferred mineral resource of 106,400 tonnes grading 2.97 g/mt Au (see news release dated October 20, 2005). Houston Lake is in the process of permitting the AHGZ for open pit mining. A revised closure plan and the application will be reviewed by Wardrop Engineering Inc. prior to submission. The permit will enable the completion of a 10,000 tonne bulk sample which is the next recommended step in the economic evaluation of the AHGZ.

The DP 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 mineral resource estimate of 53,741 metric tonnes grading 15.43 g/mt Au (59,240 short tons grading 0.45 oz/st Au) was calculated for the No. 1 Zone in 1944 by Noranda Minerals. A mineral resource inventory of 18,219 short tons grading 0.26 oz/st to a depth of 150ft was computed by Nuinsco Resources Limited in 1988.

Gold was first discovered on the Dubenski property in 1935. Three gold zones occur along a 300m (1000ft.) strike length of the east-west trending Flint Lake Shear. The Shaft Zone has a 132 foot exploration shaft and a 60 foot cross-cut was developed in 1945. An historic mineral resource of about 355,286 tonnes averaging 6.32 g/mt Au (322,310 short tons averaging 0.184 oz/st Au) was calculated for the Shaft Zone to a depth of 150m (492ft.) by Avalon Ventures Ltd. in 1998.

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.

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.
