VANCOUVER, May 18 /CNW/ - Tumi Resources Limited (TSXv-TM; OCTBB-TUMIF;
Frankfurt-TUY) (the "Company"). After a thorough technical evaluation,
including three separate drill programs and a comprehensive economic review of
the Cinco Minas property, the Company has decided to withdraw from the option
agreement with Minera San Jorge S.A. de C.V. As stated repeatedly, the
Company's management is focused on enhancing shareholder value by identifying
silvergold projects of high merit with significant mine potential and it has
been determined that the Cinco Minas property does not meet the Company's
criteria.
Although a resource was established for Cinco Minas, the results of a
scoping study previously undertaken by Behre Dolbear (see press release dated
June 4, 2004) indicated a very high strip ratio for an open pit mining
operation, such indication having been confirmed by in-house studies performed
by the Company's technical consultants. Additionally, a review of an
underground high-grade mining option gave resource numbers too low to be of
interest to the Company, particularly when having to deal with a large number
of historic open stopes. In summary, a combination of a very high strip ratio
for an open pit, underground open stopes, and an option to earn only a 60%
interest with high underlying holdings costs, make the Cinco Minas property
unattractive to the Company from an economic prospective. To meet the
Company's exploration goals, a project must also be able to reach "advanced
project status" quickly and cost effectively. Neither the open pit nor the
underground options meet the standard for operational size and economic
potential.
The Company, however, is pleased that it can now concentrate its efforts
on the La Trini silver-gold project, located within the Hostotipaquillo mining
district, underlain by the Tertiary Sierra Madre Occidental volcanic province
and younger intrusive rocks. The La Trini silver-gold project is currently
evaluated as an open-pit mining target.
The Company remains focused on silver and gold exploration in Mexico and
will move ahead with current exploration activities while it also aggressively
identifies and evaluates additional exploration projects of high merit that
meet the Company's corporate and technical objectives.
