هدف از این پژوهش بررسی‌های دورسنجی و مغناطیس هوابرد در ذخایر مس پورفیری برای شناسایی واحدهای دگرسانی و مناطق با تمرکز بالای کانه‌زایی طلاست. بدین‌منظور هشت اندیس با تمرکز متفاوت طلا انتخاب و مرز مطالعاتی و کانی‌های مهم دگرسانی در آنها توسط پردازش داده استر مشخص شدند. داده‌های مغناطیسی نیز با فیلترهای مختلف پردازش و بر اساس مرزهای تعیین‌شده برای هر اندیس برش‌داده شدند. در مرحله بعد مناطق بارز‌شده و تغییرات میدان مغناطیس در اطراف هر اندیس، بررسی و با یکدیگر مقایسه شدند. طبق نتایج پردازش تصاویر استر زون فیلیک در منطقه گسترش زیادی دارد و با توجه به اینکه بیشتر ذخایر فقیر از طلا با دگرسانی گسترده فیلیک همراه هستند، این امر ‌پایین‌بودن مقدار طلا در این ذخایر را تأیید می‌کند. نتایج داده مغناطیسی نیز نشان داد که تغییر در شدت میدان مغناطیسی با تغییرات طلا در اندیس‌های مورد بررسی همخوانی دارد.
