15.2.2 Change of <strong>La</strong>nd Use<br />
<strong>The</strong> Company’s Change of <strong>La</strong>nd Use permit has a term of 15 years. Application for the permit required a<br />
payment to provide “environmental compensation for the change of land use”. <strong>The</strong> criteria used for<br />
determining such payment for affected forestry lands are based on information contained in the Official<br />
Federation Diary, dated September 28, 2005.<br />
• <strong>The</strong> Company’s permit covers an area of 108 Ha that is classified as semi-arid land. According to<br />
the Official Federation Diary, semi-arid lands are compensated at an approximate ratio of 3:1.<br />
Castle Gold was required to pay compensation for an area equivalent to 356 Ha.<br />
• Cost calculations are based on a cost of approximately P$0.57 per Ha (according with costs<br />
published by the government in April, 2006). Castle Gold was therefore required to pay a<br />
compensation of P$2,031,664.90. This payment was made in 2007.<br />
15.3 CLOSURE AND REHABILITATION PLANS<br />
As per the requirement of the Change of <strong>La</strong>nd Use permit, Castle Gold has submitted a reclamation plan<br />
to SEMARNAT under which Castle Gold will reclaim or rehabilitate the following:<br />
• Solution pads: fresh water will be added to the circuit for several days until cyanide<br />
concentrations are 10 ppm, then hydrogen peroxide is added until all cyanide has been destroyed.<br />
• Solution ponds: after evaporation of existing barren solution, they will be filled with neutralized<br />
material from the pad and covered with fertile soil.<br />
• Plant and Workshops: all installations will be removed from its foundations and disposed as fill in<br />
the solution ponds.<br />
• <strong>La</strong>nd restoration: all areas will be levelled and filled, then covered with fertile soil and reforested.<br />
Implementation of reforestation activities in the impacted surfaces through terraces, infiltration<br />
ditches, considering local vegetation.<br />
<strong>The</strong> reclamation plan activities are estimated to cost P$160,000.<br />
