iii iiiiiiiiiiiiiiu <br />~~~ <br />~~~ <br />San Luis P~o~ect News <br />Fa111989 Informah'on on the San Luis Project, Costilla County, Colorado <br />SAN LUIS PROJECT UPDATE <br />Battle Mountain Requests Amendment to San Luis <br />Project Permit <br />On October 10, Battle Mountain Gold <br />applied for an amendment [o its previ- <br />ously-approved permit for the San Luis <br />Project. <br />Basically, the amendment eliminates <br />heap leach operations. Once the changes <br />are approved all San Luis Project ore will <br />be processed in tanks within [he plant <br />area, rather than through a combination of <br />milling and heap leaching. <br />Under the proposed changes, we will <br />build a mill with enough size to handle all <br />the ore we produce. We also will modify <br />the outline of three areas where we will <br />place overburden. <br />Other aspects of the project will <br />remain the same as covered by the <br />Colorado Mined Land Reclamation Board <br />(MLRB) permit issued on March 22, <br />1989. <br />WHY CHANGE? <br />Our current permit is an effective and <br />environmentally sound way of developing <br />the San Luis Project, as is our new <br />Q <br />TO TOWN OF SAN LUIS <br />3.4 MILES ___ <br />f <br />~~ . <br />application. The existing permit was <br />issued by [he MLRB after Battle Mountain <br />met or exceeded all MLRB performance <br />standards. <br />However, as we have teamed more <br />about the project, our engineers and <br />consultants have been working to develop <br />a more efficient and economical process- <br />ing approach, which also addresses the <br />concerns voiced by a few members of the <br />community. <br />MUCH WILL STAY THE SAME <br />The new approach we are proposing <br />will allow us to recover more gold from <br />San Luis Project ores, in a safe and sound <br />way. <br />We continue to work to improve the <br />project in concert with the community's <br />interests. <br />Bu[ before we discuss [he changes, <br />we should point out what will stay the <br />same in our plans for the San Luis Project: <br />• Our plans for mining and reclaim- <br />ing the ore bodies themselves will remain <br />WATER <br />COLLECTED <br />FOR RE-USE <br />PROCESSED ORE <br />~ ~ <br />DIVERSION <br />DITCH <br />v- ~ -- <br />o laao xooo aooo <br />9LKE IN FEET <br />the same. Tht se plans and designs already <br />have been jud3ed environmentally sound <br />by the MLRB and aze approved in the <br />current permit. <br />• We will mine the same amount of <br />ore-about 12.2 million tons in all-at the <br />same rate of 4,700 tons a day over a seven <br />to l0 year per od. Of course, actual <br />mining rates are subject to modification by <br />a number of economic and operating <br />factors which cannot be foreseen at [his <br />time. <br />• Our mule will produce the same <br />amount of barren rock, or overburden, as <br />provided for under the curtent permit, <br />although we are making. minor changes in <br />where we loct a any rock which we <br />cannot process. <br />• Our reclamation plans will remain <br />[he same, as has already been approved by <br />the MLRB. <br />• The ovl;mll permit boundary will <br />remain the satne. <br />(continued on page 2) <br />SS <br />OVERBURDEN <br />TO HIGHWAY 159 <br />~~~ 3-4 MILES <br />i \~~Oo <br />~~ ~4 <br />~\ J` <br />B~CO ~\\ 9 <br />~\'e `, <br />C~~f+'~~ ~ •\ <br />~ ~~~ <br />\\ <br />~ ~~ , <br />HAUL ROAD 1\\ <br />l\\\ o~ <br />\\ ~9 <br />\\ ~c <br />~PEHYIT SOUNDAaT <br />\ ~\ <br />~_ \ \\ of T,\ <br />TO MINE AREA <br />t/2 MILE <br />SAN LU[S PROJECT AREA Affected by Pernit Amendment <br />
