TORONTO, ONTARIO--(Marketwire - Feb. 28, 2012) - Kirkland Lake Gold Inc. ("KL Gold") (TSX:KGI)(AIM:KGI) and Queenston Mining Inc. ("Queenston") (News - Market indicators)(FRANKFURT:QMI)(OTCQX:QNMNF) are pleased to announce the results from recently completed underground and surface Diamond drilling exploration programs on their joint venture properties. These programs include underground drilling on the North AK property, on which KL Gold has the right to earn a 50% interest by expending $400,000 on exploration (see KL Gold and Queenston Mining press releases dated August 24, 2010), and a preliminary surface exploration drilling program on the existing jointly held (50%-50%) South Claims Joint Venture property.

A total of 11 underground Diamond drill holes (totalling 12,392 feet) were completed from the east end of KL Gold's 5300 level drift along the South Claims boundary and drilled southeast onto the north portion of Queenston's AK property.

The 11 underground exploration drill holes testing the north portion of the AK property were reconnaissance in nature and tested a strike length of 850 feet to the east and 500 feet to the south. Six of the drill holes returned significant intersections including:

• Drill hole 53-1922 intersected two mineralized zones and assayed 0.47 ounces per ton of gold (opt) over a core length of 4.0 feet and 0.46 opt over a core length of 7.2 feet.
• Drill hole 53-1925 intersected two mineralized zones and assayed 0.20 opt over a core length of 26.5 feet and 14.66 opt over a core length of 1.0 feet.
• Drill hole 53-1926 intersected one mineralized zone and assayed 0.40 opt over a core length of 4.3 feet.
• Drill hole 53-1927 intersected two mineralized zones and assayed 1.88 opt (uncut, 1.67 opt cut) over a core length of 5.8 feet and 1.54 opt over a core length of 1.0 feet.
• Drill 53-1965 intersected two mineralized zones and assayed 1.87 opt over a core length of 1.0 feet and 0.18 opt over a core length of 1.2 feet.

As part of a preliminary surface exploration drilling program on the South Claims Joint Venture property, five surface exploration drill holes were completed totalling 3,800 feet. One of the surface drill holes intersected the Amalgamated Kirkland Break and assayed 1.74 ounces of gold per ton (opt) uncut (0.49 opt cut) over a true width of 4.6 feet and at a depth of 400 feet below surface. The mineralization remains open in all directions. The Amalgamated Kirkland Break is located 5,000 feet south of the Kirkland Lake Main Break with an orientation similar to the Kirkland Lake Main Break.

"This reconnaissance first pass of the underground exploration program on the north portion of the AK property appears to confirm that the South Mine Complex extends onto this property. In addition, the preliminary surface exploration on the South Claims Joint Venture property indicates the potential for near surface mineralization," said Stewart Carmichael, Chief Exploration Geologist for KL Gold.

Charles Page, President and CEO of Queenston stated, "The partnership with KL Gold in exploring for the South Mine Complex on jointly held lands continues to be highly successful. We are pleased with the new drilling results as they continue to expand the footprint of gold mineralization that appears related to the SMC a further 656 feet to the southeast onto the North AK Property where it remains open."

The following table summarizes the latest underground drilling results from the North AK property in imperial units:

TW = True Width, CL = Core Length, VG = Visible Gold, Tell = Tellurides, HW = Hanging Wall CUT = cut to 3.5 opt, ?? TW = True Width Undetermined

The following table summarizes the latest underground drilling results from the North AK property in metric units:

TW = True Width, CL = Core Length, VG = Visible Gold, Tell = Tellurides, HW = Hanging Wall CUT = cut to 120 grams/tonne, ?? TW = True Width Undetermined

The North AK property adjoins the South Claims property to the east and the HM property to the south located approximately 2000 feet south of the Kirkland Lake Main Break. Combined, these properties form the heart of the joint venture where underground drilling directed by KL Gold from the 5300 foot level of the Macassa Mine has been targeting the southern and eastern continuation of South Mine Complex.

Total expenditures by KL Gold on the exploration of the North AK and Kirkland Hudson properties were $592,500, exceeding the required $400,000 expenditures, under the terms of its earn-in. KL Gold has now earned a 50% interest from Queenston in the North AK and Kirkland Hudson properties.

The South Claims were purchased by KL Gold and Queenston in April of 2007 to cover the potential down-dip extension of the SMC. KL Gold and Queenston formed a joint venture in 2007 and an underground Diamond drilling program commenced on the South Claims. 

An updated resource estimate for the South Claims Joint Venture as of January 1, 2011 outlines an indicated resource of 101,000 tons grading 1.41 opt and an inferred resource of 113,000 tons grading 1.35 opt. These resource estimates were also included as part of a broader report prepared for KL Gold dated April 4, 2011 entitled Review of Resources and Reserves of Macassa Mine, Kirkland Lake, Ontario at January 1, 2011 prepared by Glenn R. Clark, P. Eng. This report is available on SEDAR (www.sedar.com) under KL Gold's filings.

In 2009 the HM property was purchased by KL Gold and Queenston and added to the joint venture (see KL Gold and Queenston joint news release dated February 12, 2009). Recently an expansion of the joint venture was announced to include a portion of the Amalgamated Kirkland property and the Kirkland Hudson property (see KL Gold and Queenston joint news release dated August 24, 2010).

Quality Assurance & Control

KL Gold and Queenston have implemented a quality assurance and control (QA/QC) program to ensure sampling and analysis of all exploration work is conducted in accordance with the best possible practices. The drill core is sawn in half with half of the core samples shipped to the Swastika Laboratories in Swastika, Ontario or to SPJ Labs in Lively, Ontario. The other half of the core is retained for future assay verification. Other QA/QC includes the insertion of blanks, and the regular re-assaying of pulps/rejects at alternate certified labs (SPJ Labs, Swastika Laboratories). Gold analysis is conducted by fire assay using atomic absorption or gravimetric finish. The laboratory re-assays at least 10% of all samples and additional checks may be run on anomalous values.
