Sudbury, Ontario – May 18, 2010 - Houston Lake Mining Inc. (TSX.V: HLM), an advanced exploration company seeking gold, platinum group and rare metal deposits in Ontario, is pleased to announce the results from an additional 4 holes of a 4,900 metre, Phase IV diamond drill program on the Company's 100% optioned Dubenski Property. Additional core samples have been shipped to the lab for fire assay analysis.

"We continue to hit high grade-gold mineralization at the eastern edge of the Dubenski Shaft Zone deposit," commented Trevor Walker President of Houston Lake Mining. "These holes form a part of our drilling program that was designed to test the near surface continuity of the gold mineralization from the Dubsenski Shaft Zone to the Central Zone. We are pleased to see the high grade intersection from drill hole DB10-83 that suggests a significant new horizon which points us towards further untested geophysical anomalies."

He continued, "We have also taken steps to reduce time it takes to process our drill core and report results to the market. We have significantly upgraded the West Cedartree core shack facilities in order to keep pace with future drill programs and we have sourced a laboratory of closer proximity and a guarantee for faster turn-around times then what we've seen in the past. I expect to see substantial improvements in our overall drilling and processing efficiency in the next drill programs on the West Cedartree Project."

About the Dubenski Property
The Dubenski property is one of eight contiguous properties comprising the Company’s 100% owned and optioned 1,674 hectare (4,135 acre) West Cedartree Gold Project located near Kenora, Ontario. The project area encompasses three zones hosting gold resources at Angel Hill (NI 43-101 compliant), Dogpaw Lake No. 1 Vein (historic) and Dubenski Mineralized Zone (NI 43-101 compliant).
P&E Mining Consultants of Brampton, Ontario were contracted to prepare a NI 43-101 compliant Mineral Resource estimate for the Dubenski property (see press release dated November 5, 2009). The categorized Mineral Resources are:

Table 1. Dubenski Mineralized Zone Resource Estimate Utilizing Optimized Pit Shell

1. The updated resource for the Dubenski Mineralized Zone was estimated on the basis of the Oct 31/09 24 month trailing average Au price of US$895/oz and $US exchange rate of $0.92. The open pit cut-off grade of 0.65 g/t Au was derived from $C2.50/tonne mining, C$15/tonne processing, C$5/tonne G&A and 95% process recovery. The open pit portion of the resource was defined in a 50 degree slope optimized pit shell. The underground cut-off grade of 2.5 g/t Au was derived from $55/tonne mining, C$15/tonne processing and C$5/tonne G&A and 95% process recovery.


2. Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.


3. The quantity and grade of reported inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured mineral resource category.


4. The mineral resources in this press release were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council December 11, 2005.

Due Diligence
All samples reported were shipped to TSL Laboratories, an ISO accredited facility, of Saskatoon, Saskatchewan. Samples were analyzed by fire assay utilizing a 50 gram charge. All samples were assayed with an AA finish and those samples assaying above 3 g/mt gold were retested utilizing a gravimetric finish.

This news release was reviewed by Bryan McKay, P. Geo., who is a Qualified Person under the guidelines of the National Instrument 43-101.
