Aldrin Announces Uranium Laboratory Analytical Results on the Anticline Target
June 27, 2014 (Source: Marketwired) — Aldrin Resource Corp. (“Aldrin”) (TSX VENTURE:ALN) –
- The first drill hole (ALN14-008) into the Anticline Target returned multiple intervals of uranium (U) consistent with being in the halo of strong mineralization.
- The strongest uranium mineralization intervals include 148.7 ppm U over 1.5 m and 144.8 ppm U over 2.0 m (see table below for details).
- The second hole (ALN14-009) into the Anticline Target also returned U intervals consistent with being within a mineralization halo.
Aldrin Resource Corp. is pleased to announce laboratory analytical results for uranium mineralization from the first two drill holes testing the Anticline Target on the Triple M Uranium Property, which is adjacent to Fission Uranium Corp (“Fission”)’s Patterson Lake discovery. The first drill hole into the Anticline Target (ALN14-008) intersected high-count radiation zones as measured by both the down-hole gamma logger, and handheld spectrometers, as detailed in Aldrin news releases dated May 29 and June 19, 2014. Analytical results from ALN14-008 and the second hole into the Anticline Target (ALN14-009) include strong uranium mineralization over significant intervals. The most significant enrichment zones are listed in Table 1.
Drill hole ALN14-008
ALN14-008 most strongly uranium mineralized zones are: a) 53.4 ppm U over 10.0 m between 178.0 and 188.0 m, including a higher value zone of 148.7 ppm U over 1.5 m between 182.5 and 184.0 m; b) 273 ppm U over 0.5 m between 235.0 and 235.5 m; and c) 97.4 ppm U over 3.5 m between 243.0 and 246.5 m, including a higher value zone of 144.8 ppm U over 2.0 m between 243.5 and 245.5 m. A total of 24.0 m of samples > 25 ppm U are listed in Table 1.
Drill hole ALN14-009
ALN14-009’s most enriched uranium zone is 35.9 ppm U over 2.5 m between 248.5 m and 251.0 m, including a higher enrichment zone of 69.3 ppm U between 248.9 m and 249.9 m. A total of 4.7 m of sample > 25 ppm U from ALN14-009 are reported in Table 1. Uranium in ALN14-009 and ALN14-008 is consistent with both being in a halo of mineralization, with ALN14-008 likely being nearer to the source.

Background in the meta-sedimentary rocks in the target area is 2 ppm U or less.
Samples were selected based on elevated responses in hand-held spectrometers and the down-hole gamma logger. The 10.0 m zone of 53.4 ppm U between 178.0 and 188.0 m reported above for drill hole ALN14-008 can be compared to hand-held RS-125 spectrometer measurements (made every 0.25 m; as detailed in the news release dated May 29, 2014), which established an average of 13.8 ppm U over 10.25 m between 176.0 and 186.25 m. The high value zone of 144.8 ppm U over 2.0 m between 243.5 and 245.5 m reported above for ALN14-008 compares well to the highest down-hole logger gamma counts zone which reached 1850 counts per second (CPS) between 243.1 m and 246.2 from the down-hole logger, as reported in the news release of May 29.
Most samples were 0.5 m or less in thickness. The core was (NQ = 49 mm diameter) was split at the field camp, and sampled with 1/2 of the core bagged and delivered securely by Aldrin personnel to SRC Geoanalytical Laboratories (“SRC”) in Saskatoon, which is an ISO/IEC accredited facility. SRC analyzed the samples using their ICP1 routine, which provides both partial and total digestion followed by multi-element inductively coupled plasma – optical emission spectroscopy (ICP-OES) as well as analyzing for the important pathfinder element boron (further details of analytical procedures are available on SRC’s website www.src.sk.ca). Sample results were composited based on weighted averages to give the reported interval values.
Total digestion values are reported above and in Table 1. Partial digestions for the more enriched samples are close to the total digestion values. For example, partial digestion values average +90% of the total digestion values for the ten most enriched samples in drill hole ALN14-008 are between 116 ppm and 273 ppm U. Most of the uranium being released by partial digestion in the most mineralized samples is consistent with the uranium being hosted in potential ore minerals pitchblende or uraninite rather than more refractory minerals.
Boron as pathfinder element
Boron (B) is an important pathfinder element for uranium exploration, where it can occur in the mineral dravite or clay minerals derived from dravite. Strongly elevated boron values occur in drill hole ALN14-008, with the three highest values at 1700 ppm B, 1130 ppm B, and 926 ppm B. The remaining 87 samples from ALN14-008 range between 14 ppm B and 370 ppm B. Interestingly, some of the most boron enriched samples are adjacent to uranium mineralized zones, supporting boron’s utility as an aid to identifying haloes to uranium mineralization. For example, the two most boron enriched samples of 1700 ppm B and 1130 ppm B respectively occur immediately adjacent to, but outside, the uranium mineralized zone of 97.4 ppm U over 3.5 m between 243.0 and 246.5 m.
Consistent with being in the halo of significant mineralization
Aldrin believes the uranium mineralization in drill holes ALN14-008 and ALN14-009 is consistent with being within a halo of uranium mineralization centered in the Anticline Target. Aldrin further believes that the analytical results and down-hole gamma logging results of ALN14-008 and ALN14-009 compare encouragingly to haloes of high-grade uranium mineralization elsewhere in the Athabasca Basin, including pre-discovery drill results from Fission Uranium Corp. (‘Fission”)’s spectacular Patterson Lake discovery on their PLS property located adjacent to Aldrin’s property. Fission’s 2012 drill program is described in the Alpha Minerals Inc (“Alpha”) 43-101 technical report dated April 2013 [written for Alpha before their merger with Fission and available on www.sedar.com and the information provided below is summarized from that source. Aldrin has not verified the data reported in the 43-101 technical report. Note that Fission/Alpha reports using the same type of Mount Sopris 2PGA-1000 down-hole gamma logger used by Aldrin. In the report’s description of their drill history, Fission/Alpha reports their 15th hole in 2012 (DDH PLS12-015) encountered two zones with high gamma counts of 1483 CPS and 3234 CPS, respectively, and returned highest uranium analysis of 156 ppm U and maximum boron value of 216 ppm. Fission/Alpha’s 16th and last drill hole (DDH PLS12-016) of their winter-spring program was located 673 m northeast in the same conductive corridor and intersected high counts of 4197 CPS and 6032 CPS, corresponding to 208 ppm U over 3.1 m, and 224 ppm U over 7.1 m respectively, as well as a reported maximum boron value of 621 ppm B. The next autumn, Fission returned to drill their discovery hole (DDH PLS12-022) as a 10 m step out from this hole DDH PLS12-016. Aldrin recognizes that our gamma counts and uranium results are not yet as high as Fission/Alpha’s DDH PLS12-016, and we also note that mineralization on Fission’s adjacent PLS Property is not necessarily indicative of the mineralization on the Triple M Property. However, Aldrin is very encouraged to resume drilling after completing some high-resolution ground geophysical surveys, and believes we may be well on the way to discovery at the Anticline Target.
Johnathan More, CEO and Director remarked, “I am pleased with the strong analytical results demonstrating substantial intervals of uranium mineralization at our Anticline Target. I believe we may be well on our way to a material discovery.”
