Small Mine Development, LLC Key Developments

Dateline Resources Ltd. Appoints Small Mine Development LLC as the Underground Mining Contractor for its 100% Owned Gold Links Gold Mine in Colorado, USA

Dateline Resources Ltd. announced that it has appointed Small Mine Development LLC (SMD) as the underground mining contractor for its 100%- owned Gold Links Gold Mine in Colorado, USA (Gold Links). The appointment represents a critical step towards the scheduled commencement of small-scale mining at Gold Links next month. Gold Links sits at the south end of a regional gravity low within the Colorado Mineral Belt which is an established gold mining region. This mineralised trend continues north-northeast along the gravity low and includes the Leadville mining district that has past production from the Colorado Mineral Belt of 20-25 million ounces of gold. After a competitive bidding process, SMD was selected to commence exploration development on two prospective areas within the Gold Links project area. SMD specializes in underground and hard- rock mining, and has worked with both large and small companies to successfully bring projects from exploration and engineering to development and production through the utilisation of safe, productive and innovative mining solutions. SMD will initially commence development on ore from a ramp at the Upper Gold Links zone, which was a previously reported sampling program that resulted in an average channel sample of 22.75g/t Au and 64.33g/t Ag over approximately 30 metres (100ft), with the best samples of 151g/t Au and 380g/t Ag, 30g/t Au and 153g/t Ag, and 28.6g/t Au and 42.9g/t Ag. Historical records from the Upper Gold Links zone state multiple ounce per tonne production, which is line with Dateline's recent sampling results. On completion of the ramp at Upper Gold Links, SMD will commence development of a ramp to access the in-situ broken ore from the Sacramento zone. The Sacramento zone was mined using the shrinkage stopping method between 1898-1906, producing approximately 18,000oz Au and 400,000oz Ag at a time when the price of gold was USD 20 per ounce and the silver price of USD 0.60 per ounce. The historical production records indicate that the cost of production from the Sacramento zone was USD 15 per tonne (mining, transport, and smelting).
