Houston Lake Mining Intersects 4.58 g/t Gold Over 1.7 Metres on Dubenski Property Sudbury, ON June 25, 2010 FSC / Press Release Houston Lake Mining Intersects 4.58 g/t Gold Over 1.7 Metres on Dubenski Property Sudbury, Ontario CANADA, June 25, 2010 /FSC/ - Houston Lake Mining Inc. (TSX - VX: HLM, OTCBB_Pink_Sheets: HLKMF), is an advanced exploration company which has prospected and strategically acquired contiguous gold properties in Northwestern Ontario with the objective of transitioning into production. HLM also seeks platinum group and raremetal deposits in Northwestern Ontario. HLM is pleased to announce the results from the final 4 holes of a 4,900 metre, Phase IV diamond drill program on the Company's 100% optioned Dubenski Gold Property. "These holes conclude our Phase IV program which has demonstrated that the previously named Shaft and Central Zones are in fact a continuous Dubenski Mineralized Zone (DMZ) that is at least 425 metres in length. As well we have further demonstrated that the deposit hosts significant widths with high-grade structures in the gold deposit. In fact with Phases I-IV inclusive, 21% of our holes have proven intersections greater than or equal to 10 grams per tonne gold for a length greater than or equal to 1metre in the DMZ," commented Trevor Walker, President of Houston Lake Mining. "While only drilling to a maximum depth of 130m vertical, we have not tested the deeper potential of this deposit. Our data suggests the mineralization strengthens with depth, therefore the next planned program in 2010 is to target the down-dip and down-plunge extension of the DMZ in order to guide the strong potential to build ounces outside of the existing mineral resource in the future. More specifically, we are in the midst of planning drill holes 100-215 metres below the existing drilling to date. Looking forward, we are excited to display to our shareholders the extent of the DMZ." Subsequent to a Phase V drilling, HLM plans on updating the resource calculations on the DMZ in order to encompass all drilling since the calculation released on November 5, 2009. -------------------------------------------------------------------- Hole From To Interval Au Interval Au Number (m) (m) (m) g/mt (ft) oz/st -------------------------------------------------------------------- DB10 89 111.00 123.60 12.60 1.77 41.34 0.057 -------------------------------------------------------- Including 113.50 121.30 7.80 2.22 25.59 0.071 -------------------------------------------------------- Including 114.10 115.80 1.70 4.58 5.58 0.147 -------------------------------------------------------------------- DB10 85 84.75 105.45 20.70 1.60 67.92 0.051 -------------------------------------------------------- Including 84.75 88.60 3.85 0.98 12.63 0.031 -------------------------------------------------------- 90.50 101.00 10.50 2.46 34.45 0.079 -------------------------------------------------------- Including 92.10 95.20 3.10 3.26 10.17 0.104 -------------------------------------------------------------------- DB10 86 89.70 110.60 20.90 1.04 68.57 0.033 -------------------------------------------------------- Including 89.70 93.70 4.00 1.33 13.12 0.042 -------------------------------------------------------- 97.70 100.00 2.30 3.74 7.55 0.12 -------------------------------------------------------- 109.90 110.60 0.70 2.14 2.30 0.068 -------------------------------------------------------------------- DB10 82 91.00 111.50 20.50 0.94 67.26 0.03 -------------------------------------------------------- Including 91.00 92.00 1.00 1.06 3.28 0.034 -------------------------------------------------------- 98.00 101.80 3.80 1.97 12.47 0.063 -------------------------------------------------------- 106.35 111.50 5.15 0.89 16.90 0.028 -------------------------------------------------------- Including 106.35 106.60 0.25 5.8 0.82 0.187 -------------------------------------------------------------------- ---------------------------------------------------------------------- Drill Northing Easting Collar Azimuth Drill Drill Hole # Dip Hole Hole Length Length (Metres) (Metres) (Degrees) (Degrees) (m) (ft.) ---------------------------------------------------------------------- DB10-89 5464230.72 438636.24 360 -45 143 469 ---------------------------------------------------------------------- DB10-85 5464232.89 438575.80 360 -45 113 371 ---------------------------------------------------------------------- DB10-86 5464232.30 438590.86 360 -45 119 390 ---------------------------------------------------------------------- DB10-82 5464220.14 438536.39 360 -45 134 440 ---------------------------------------------------------------------- A map of the drill holes and collar locations are included in the corporate presentation that is available for download on the Houston Lake Mining website at www.houstonlakemining.com. 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 ------------------------------------------------------------------- Indicated Inferred ------------------------------------------------------------------- Cut-Off Au G/T Tonnes Au g/t Au Oz. Tonnes Au g/t Au Oz. ------------------------------------------------------------------- Pit 0.65 g/t 524,000 3.55 59,800 12,000 1.96 800 ------------------------------------------------------------------- UG 2.5 g/t 27,000 3.26 2,900 10,000 3.32 1,000 ------------------------------------------------------------------- TOTAL 551,000 3.53 62,700 22,000 2.57 1,800 ------------------------------------------------------------------- 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 .92. The open pit cut-off grade of 0.65 g/t Au was derived from C$2.50/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. About Houston Lake Mining Inc. Houston Lake is an advanced, vertically integrated resource exploration company.
