  • Completed a detailed geological interpretation and exploration report on its highly prospective, 100%-owned NMX East property in northern Quebec
  • Results from the field reconnaissance survey included the discovery of three distinct lithium-bearing intrusions, which have been characterized as LCT (lithium-cesium-tantalum) pegmatites, and the generation of clear drilling targets
  • 11 samples returned over 129 ppm Li2O, up to 689 ppm Li2O; 5 samples returned over 50.3 ppm Cs, up to 83.6 ppm Cs; 22 samples returned over 481 ppm Rb, up to 2140 ppm Rb; and 11 samples returned over 27ppm Ta, up to 77.1 ppm Ta

Vancouver, BC / September 21, 2016 – Durango Resources Inc. (TSX.V-DGO), (the “Company” or “Durango”) announces that, further to its news release of September 20, 2016, Durango has completed a detailed geological interpretation and exploration report on its highly prospective, 100%-owned NMX East property in northern Quebec.

Results from the field reconnaissance survey included the discovery of three distinct lithium-bearing intrusions, which have been characterized as LCT (lithium-cesium-tantalum) pegmatites, and the generation of clear drilling targets.

Summary of Assays

Typical LCT (lithium-cesium-tantalum) pegmatites are marked by prominent accumulation of Li, Cs and Ta (sometimes with Rb and other elements), which are exhibited to an anomalous degree in the pegmatite assays returned from the NMX East property.

Out of a total of 79 samples taken at NMX East, 47 samples were taken from pegmatite outcrops. Out of this group of pegmatite samples: 11 samples returned over 129 ppm Li2O, up to 689 ppm Li2O; 5 samples returned over 50.3 ppm Cs, up to 83.6 ppm Cs; 22 samples returned over 481 ppm Rb, up to 2140 ppm Rb; and 11 samples returned over 27ppm Ta, up to 77.1 ppm Ta. Summary and ranges of anomalous results are summarized in Table 1. Assays are shown against pegmatite outcrops in Figure 1.

Interpretation of Lithium, Cesium, Tantalum, and Rubidium Anomalies

Results from the exploration program at NMX East clearly indicate the presence of three distinct pegmatite intrusions which exhibit significant lithium, cesium, tantalum, and rubidium anomalies. One intrusion occurs on the property’s East Block, while two intrusions occur on the South Block.

The Nemiscau Region exhibits a markedly limited amount of bedrock exposure, which produces a very challenging environment for surface sampling. On average, there is approximately less than 5% exposure on the NMX East property and a large portion of the surrounding region. Evidence suggests that the majority of pegmatite bodies in the Nemiscau Region are obscured beneath the glacial diamict which blankets the region. Nemaska Lithium Inc.’s recent drilling results also report mineralized intercepts as deep as 500 metres below surface (2). As such, Durango’s geological team suspects the three viable lithium-bearing LCT pegmatites, which occur at surface on Durango’s NMX East property, may represent smaller exposures of potentially much larger intrusions which may continue both at depth, laterally, and along strike.

Furthermore, most LCT pegmatites exhibit concentric zonation, particularly of spodumene (Li), pollucite (Ce), columbite-tantalite (Ta), and beryl (Be) mineralization. This mineralization is typically concentrated in the core margin to core zone of the pegmatite intrusion, with dilute quantities in the intermediate zone. This zonation is illustrated in Figure 2.

Durango’s geological team therefore interprets these moderate lithium, cesium, tantalum, and strong rubidium anomalies at surface to be a potential indication of significant spodumene mineralization at depth. The next steps at NMX East will include extensive stripping and/or drilling of these mapped pegmatite intrusions in order to determine the real nature and extent of the intrusive bodies.

Marcy Kiesman, CEO of Durango, comments, “The results from this campaign indicate the existence of three newly-discovered LCT pegmatite intrusions on the NMX East property and serve as an excellent first step in the progression of the project. Lithium-bearing pegmatites are a complex deposit type, considering the zonation and nature of mineralization within the intrusions and the challenging region in which they choose to manifest. Durango is exceptionally pleased to have discovered three distinct LCT pegmatite intrusions on the property and plans to explore these targets further in the coming exploration season, by means of stripping and drilling.”

All samples were grab samples and were analyzed by ALS Minerals, Val-d’Or (Quebec). The analytical methods used correspond to ALS codes ME-MS81 and Be-ICP81.
