Halifax, NS – GoGold Resources Inc. (TSX: GGD) (“GoGold”) is pleased to announce that it has uncovered additional zones of high grade gold on surface at the Greta project at its Santa Gertrudis Gold Mine located in Sonora state, Mexico. GoGold’s Trench 318 uncovered (18m of 32.8 g/t Au). The largest zone of a few areas consists of three subparallel zones of mineralization that dip about 20° to the west and has dimensions of 660 meters along the north-south strike and 370 meters down dip. This zone is approximately 12 meters thick and is tightly confined to a thin layer that gives the appearance of a bedding plane or a flat-lying structural zone. The zone is notable for a very high-grade gold layer from one to ten meters thick that outcrops on surface in numerous locations.
A mining program is under way with material being shipped to a 150 tonnes/day custom mill for processing by grinding, cyanidation and zinc precipitation. There have been 425 gold ounces poured from the mill to date in the month of October. Gold recoveries are expected to be plus 85% once minor modifications to the mill are complete.
A total of 7,800 tonnes have been shipped to the mill at an average head grade of 14 g/t Au using a cut-off grade of 10 g/t Au. Ore below this grade is being stockpiled to be processed in the vat leach plant once construction is complete which is expected to be March 2017. The ore is moved from the surface pit to the laydown yard and then a sample is collected from each ore pile. It is rolled then cone and quartered and fire assayed for gold and silver at the Laboratorio Tecnologico de Metalurgia LTM SA de CV in Hermosillo, Mexico.
Highlights from a GoGold Trenching Program not previously released include some significant results one of which was 18 metres of 32.77 grams per tonne gold along the surface of the zone;

The high-grade mineralization outcrops at surface towards the north, where it has been previously drilled by Phelps Dodge with reverse circulation and diamond drill holes. Some of the historical results from drilling include;
- RC Hole GR-213: 0.0 to 4.5m @ 9.55 g/t Au (vertical hole)
- RC Hole GR-214: 0.0 to 3.0m @ 24.5 g/t Au (vertical hole)
- DDH GR-306: 12.8 m to 18.9m @ 26.6 g/t Au (angled hole)
In 2005, Sonoran Resources carried out a drilling program using a blast hole drill. A total of 105 vertical holes, spaced on a 5m x 5m grid, were drilled to a depth of 10m over an area of 110m by 40m where the high grade mineralization was known to outcrop. Results from this drilling also confirmed the presence of the 2 to 10m thick layer of high grade gold mineralization and some highlights include;
- Hole ONT-007: 0.0m to 3.0m @ 11.5 g/t Au
- Hole ONT-011: 0.0m to 5.0m @ 16.6 g/t Au
- Hole ONT-035: 0.0m to 5.0m @ 26.5 g/t Au
- Hole ONT-053: 5.0m to 10.0m @ 28.5 g/t Au
- Hole ONT-063: 0.0m to 10.0m @ 10.8 g/t Au
- Hole ONT-097: 1.0m to 5.0m @ 21.3 g/t Au
- Hole ONT-098: 1.0m to 4.0M @ 15.3 g/t Au
In 2015, GoGold carried out prospecting, mapping and channel sampling programs on the Greta Deposit. See map below:
In 2015, GoGold completed several short diamond drill holes to confirm the high grade mineralization and obtain samples for metallurgical test work. Some of the significant results are shown in the following table. (These drill results were released in the Press Release dated September 28, 2015).

Lab Preparation and Assay
The sealed and tagged sample bags are transported to the ActLabs facility in Zacatecas, Mexico. ActLabs crushes the samples and prepares 200-300 gram pulp samples with ninety percent passing Tyler 150 mesh (106μm).
The pulps are assayed for gold using a 50 gram charge by fire assay (Code 1A2-50) and over limits greater than 10 grams per tonne are re-assayed using a gravimetric finish (Code 1A3-50). Silver and multi-element analysis is completed using total digestion (Code 1F2 Total Digestion ICP).
