Eastmain Resources Inc (TSE:ER) and Azimut Exploration Inc. (CVE:AZM) have drilled up to 76.1 g/t of gold in the final seven drill holes (1,455 metres) from a 12-hole, phase 1 drilling program (2,510 m) and received new prospecting results from the Eleonore South joint venture property in James Bay, Quebec, the company said on Monday.

Drilling Highlights

  • 1.14 g/t Au over 6.0 m from 153.0 m (Hole ES16-54);
  • 1.58 g/t Au over 12.0 m from 147.0 m, including 4.67 g/t Au over 2.7 m (Hole ES16-55);
  • 76.1 g/t Au over 1.55 m from 152.95 m (Hole ES16-57)


Boulder Grab Sample Highlight

  • 247 g/t Au (sub-angular boulder sample with visible gold).


Gold mineralization identified in the first phase of the 2016 program occurs in a prospective corridor at least 3 km long by 500 m wide within a tonalite intrusion. The corridor is bounded to the south by metasediments.

The preliminary interpretation of the first phase of drilling results indicate a potential for high-grade gold mineralization related to late-magmatic quartz-feldspar pegmatites and strongly altered biotite-actinolite schist hosted by the tonalite intrusion. Other mineralized zones may be present in this part of the property, including the southern tonalite-metasediment contact.

The Phase 2 drilling program (2,500 m) will begin in early 2017 after a thorough data integration and interpretation.

Diamond drilling results

Holes ES16-53 to ES16-57 targeted the tonalite complex intersecting gold mineralization associated to pegmatite emplacement, quartz veins and veinlets and variable amounts of biotite, albite and actinolite alteration along with low levels of disseminated pyrite, pyrrhotite and arsenopyrite. (See TABLE 1 for mineralized interval details, including previously reported drill results)

Hole ES16-53 (201 m) was drilled to complete a fence of holes (geological section) including ES16-48, -52 and -49. An anomalous section of 0.5 g/t Au over 19.5 m with arsenopyrite (0.5% to 1%).

Hole ES16-54 (198 m) was drilled as a step-out 50 m to the west of ES16- 48 (8.88 g/t Au over 2.5 m). An anomalous section of 0.75 g/t Au over 1.5 m with arsenopyrite, pyrrhotite and visible gold is present. A further interval of 1.14 g/t Au over 6.0 m was intersected in greyish tonalite and grey pegmatite with pyrite, pyrrhotite and arsenopyrite.

Hole ES16-55 (201 m) was drilled to extend the geological section of ES16-51 to the northwest. A section of 1.58 g/t Au over 12.0 m was encountered in grey tonalite with arsenopyrite and pyrrhotite. A second anomalous section of 0.59 g/t Au over 28.5 m is related to albite- actinolite alteration with arsenopyrite and pyrrhotite. A third section returning 1.09 g/t Au over 1.5 m includes visible gold in a folded grey quartz veinlet.

Hole ES16-56 (201 m) was drilled as a 50-metre step-out to the east of ES16-51 and ES16-55 returning a narrow interval of 2.84 g/t Au over 1.5 m.

Hole ES16-57 (252 m) intersected 76.1 g/t Au over 1.55 m. It was drilled to test an area south of a trench that returned several anomalous gold values. The intercept is located within a zone of strong albite- actinolite alteration containing scheelite, tourmaline, minor pyrite and arsenopyrite.

Holes ES16-58 and -59 (201 m each) explored a metasedimentary sequence along the contact with a second tonalite intrusion several km southwest of the Moni showing. No significant results were obtained.


A total of 28 grab samples were collected mostly from outcrops. Grab samples are selective by nature and unlikely to represent average grades.

The gold results have been summarized by Azimut as follows: eleven samples returned grades higher than 0.1 g/t Au, including seven samples with values higher than 0.5 g/t Au. The most significant value is a sub-angular boulder of quartz-feldspar pegmatite with disseminated arsenopyrite and visible gold, which assayed 247 g/t Au.

“These early stage results demonstrate the property’s potential for high-grade gold mineralization associated with a large-scale intrusion-related hydrothermal system. Of significance, all ten of the Phase 1 drill holes within the prospective corridor’s tonalite intrusion encountered mineralization and most holes recorded several intercepts per hole,” said Claude Lemasson, Eastmain President and CEO.

The Eleonore South Property is a three-way joint venture between Azimut Exploration (26.6%), Eastmain Resources Ltd. (36.7%), and Les Mines Opinaca Ltee. (36.7%), a wholly-owned subsidiary of Goldcorp Inc. (TSE:G)(NYSE:GG). Azimut is the JV manager of the current program, which includes Phase 2, to be completed in 2017.
