This brochure contains statements that plan for or anticipate the future. Forward-looking statements include statements about the Company's ability to develop and produce gold or other precious metals, statements about our future business plans and strategies, statements about future revenue and the receipt of working capital, and most other statements that are not historical in nature. Forward-looking statements are often identified by words such as "anticipate," "plan," "believe," "expect," "estimate," and the like. Because forward-looking statements involve future risks and uncertainties, there are factors that could cause actual results to differ materially from those expressed or implied, including those described in our filings with the SEC. Prospective investors are urged not to put undue reliance on these forward-looking statements.

GOLD COMMENTARY 69 NYSE American: GORO ➢ London Metal Exchange (LME) to ban day drinking ➢ This is apparently an issue at the LME?

70 ➢ Metal traders banned from workday boozing “The days of long, booze-fuelled City lunches appear to be nearing an end as the London Metal Exchange becomes the latest firm to introduce a booze ban.” The exchange has said that all staff who work on its trading floor can no longer drink during working hours. The ban affects about 120 personnel - from traders to clerks - of nine different firms who work in the Ring. The move follows similar rules on alcohol and drugs from Lloyd's of London, introduced earlier this year. 'No ambiguity' Ben Willmott, head of public policy at human resources trade body the CIPD, said it was common for firms to have a policy around how much alcohol was reasonable in working hours, even in industries which were not safety-critical. "It makes sense to have a policy so that there is no ambiguity. A policy may well allow appropriate lunchtime drinking. It doesn't have to be a zero-tolerance policy." Mr Willmott said having a policy on drinking made it easier for managers to raise the issue if there was a problem and to highlight the support available.
