HLM completes initial Mobile Metal Ion (MMI) geochemical survey on the Pakeagama Rare Metals Property in Northwestern Ontario

Houston Lake Mining Inc. (TSX.V: HLM), is a mining exploration
company which is actively exploring for rare metals and currently
focusing on its 100% owned and optioned Pakeagama Rare Metals Project in
northwestern Ontario, Canada. HLM is pleased to announce the completion
of a Mobile Metal Ion ('MMI?) geochemical survey on 60% of this 1,792
hectare (4,424 acre) property.

In June 2011, Peter J. Vanstone P.Geo. the qualified person for the
project, conducted an MMI orientation soil survey over the exposed
Pakeagama Lake pegmatite. The results of this survey identified 15
elements that had a definitive response to the pegmatite, and
specifically established a characteristic cesium, lithium, and rubidium
soil MMI response. It also allowed the Company to define the best soil
sample depth range for future MMI surveys on the property. Later in
2011, Mr. Vanstone supervised a detailed reconnaissance MMI soil survey
of the four more southerly claims.

The Company is pleased to announce that the regional survey returned
very encouraging MMI results. Specifically, elevated cesium, lithium and
rubidium MMI values are concentrated both to the northwest and southeast
directions within the property and coincident with the assumed
orientation of the Pakeagama Lake pegmatite. The MMI geochemical
signatures are of similar amplitudes to that of the orientation survey
over the Pakeagama Lake pegmatite itself. As a result, the Company is
planning a preliminary exploration drill program, which, in part will
reinforce the MMI geochemical exploration model defined by the
orientation survey.

'The objective of the MMI geochemical program is to aid in the targeting
and planning of a Phase I diamond drill program. Upon completion of the
MMI survey and a future Phase I diamond drill program, the knowledge
gained should provide us with a unique and cost effective geochemical
survey tool we can use in further definition of our Pakeagama Lake rare
metal pegmatite, or other similar pegmatites in central Canada?, said
Trevor R. Walker, President of HLM.
