DAR ES SALAAM, TANZANIA -- (MARKET WIRE) -- 06/29/11
Douglas Lake Minerals Inc. (the "Company" or "Douglas Lake") (OTCBB: DLKM) is pleased to announce the discovery of a promising gold exploration target over an area of approximately 7.2 km(2) on their Kwandege prospect. Kwandege is a prime target on one of the Company's four (4) prospecting licenses covering an area of approximately 800km(2) in the Handeni district in the United Republic of Tanzania. Exploration is conducted through the Tanzanian registered subsidiary DLM (Tanzania) Ltd.
Ground exploration conducted over the past six months led to the creation of drill targets on the Kwandege prospect. Drilling is set to commence on July 25, 2011. The Kwandege target is part of an anomalous gold area covering 18km(2). As such, the work conducted here has the added value of continuously improving the model for the style of mineralization on other already existing targets on the Company's properties. Aeromagnetics and radiometrics in combination with widely spaced (500 m) soil sampling, as announced in previous press releases, were used to generate priority areas such as Kwandege (Fig. 1).

Yellow dots on the diagram are approximate locations of Douglas Lake targets to be investigated or in the process of being explored. An enlargement of the Kwandege area is represented in Figure 2.
Within the 18km(2) mineralized Kwandege target, an area of approximately 9.75km(2) was outlined as being of high priority based on existing geophysics, geochemistry and the presence of artisanal workings along a 400 m strike distance within this area.
The soil sampling program at Kwandege is continuing with 4027 samples having been submitted to SGS Mwanza, an internationally accredited laboratory, for geochemical analyses including 806 standards and 70 blanks. Sampling was conducted every 25 m along 100 m spaced N-S lines. Assay results for 1960 of these samples have been received up to 24 June 2011 (including 85 standards, 36 blanks and 26 duplicates). Interpretation of these results has produced several anomalies supported by Au values and ground geophysics.
Ground geophysics over an area of approximately 9.75 km(2) at Kwandege was completed on 16 June 2011. Preliminary findings are extremely significant in terms of gold mineralization. Geophysical work was conducted with standard calibrated geophysical instrumentation. The ground based Dipole-Dipole/Pole Dipole Induced Polarization (IP) as well as Fixed Loop TDEM and Ground Magnetic Surveys were conducted by Spectral Geophysics, a company with wide experience in Africa.
The line spacing for IP geophysics was 100 m with measurements taken every 25 m, for ground magnetics the spacing was 100 m with measurements every 10 m. Line spacings for radiometric measurement are 50 m with measurements every 25 m. All geophysics lines were orientated N-S. EM work was conducted on 200 m line spacing and stations every 50 m. A fixed loop of 1000 m X 500 m was used.
Highlights:
1. The Kwandege target's mineralization zone covers an area of approximately 18 km(2)(Fig. 2). To date 45% (8.1 km(2)) of this has been covered by detailed ground geophysics and soil sampling, delineating gold mineralization over an area of approximately 7.2 km2 (89% of the 8.1 km(2) area). The main axis of mineralization trend WNW-ESE over a distance of 2.2 km and 800 m wide. 2. A second axis of mineralization trend NNE-SSW over a distance of 3 km, the width of which is undeterminable as some soil sample results over this zone have not been received (Fig. 2). Twenty five percent (25%) of soil samples along these zones contain Au values of 60 ppb or more, up to approximately 4 900 ppb. 3. High gold values at Kwandege are consistently present along WNW-ESE linear structures coinciding with zones of low resistivity, flanked by zones of high resistivity, which may be interpreted as shear zones. Gold anomalies are also related to zones of intensive chargeability present as linear (NNE-SSW orientated) or massive high chargeability semi- circular bodies (Fig. 2). On a target zone and regional scale there is a close relationship between gold and zones of low magnetic response and the transition of these to high magnetic response areas.

Close line spaced geochemical results have been received for the area N and E of the blue line. Yellow dots are gold values between 30 ppb and 4 900 ppb as determined in soil samples. Green solid line = High chargeability zone, Purple solid line = Low resistivity zone. The area of gold mineralization outlined to data is indicated by the red dotted line.
4. Drill targets were generated of which the positions are outlined on Fig. 3. The drilling program will commence with individual holes at A and B (Fig. 3) following on with a 1.6 km line of holes in between A and B. This will be followed by holes at C and D, continuing for a distance of 450 m NE and SW of both locations. A line of holes (450 m strike length) is planned between E and F as well as between F and G (450 m strike length) depending on the nature of the anomaly as will be revealed by the first three holes at E, F and G. The total potential drillable strike length of the target zones at Kwandege is thus 3 400 m. Preparations are currently under way to commence with the drilling program on 25 July 2011.
"These findings are indeed very encouraging. In addition to the created drill targets an important aspect is the potential of this area in the context of the Handeni district. Kwandege represents one of several Douglas Lake targets where the combination of significant exploration parameters, which are internationally acceptable and essential for the delineation of potential mineralized targets, are present", remarked Dr. Douglas Boateng, CEO and President of Douglas Lake.
The soil sampling, ground magnetic and IP programs, to eventually cover an area of 25 km(2) around the Kwandege target, are on-going and managed from an established camp on site. Exploration of other targets to the south, southeast and west of Kwandege will also be managed from here.

"We firmly believe that our unbiased approach to the mineralization style in the Handeni district and the subsequent continued development of our exploration model is the reason for our success in delineating significant gold targets on our properties. The Kwandege program is geared to delineate potentially economic concentrations of gold and any associated metals", says Dr. Reyno Scheepers, President of Exploration, DLM (Tanzania) Ltd.
