Kabupaten Solok, Provinsi Sumatra Barat mempunyai potensi sumberdaya minerallogam. Studi ini bertujuan untuk menentukan daerah potensi mineralisasi mineral logam Fe-Cu-Pb-Zn di Kabupaten Solok dengan menggunakan kombinasi model statistik rasio frekuensi dan sistem informasi geografis. Analisis dilakukan terhadap data sebaran litologdan struktur geologi serta data 4 jenis unsur unsur dari 433 sampel geokimia endapan sungai aktif. Hasil kajian menghasilkan sebaran spasial sebelas daerah potensi mineralisaslogam Fe-Cu-Pb-Zn. Penelitian lapangan dilakukan di daerah potensi Pisauilang, Kotanarudan Air Bertumbuk, ditemukan cebakan bijih besi di tiga lokasi dengan Fe sebagai unsupenyusun utama serta Cu, Pb, dan Zn, sebagai unsur ikutan. Kandungan bijih besi berupa Fe 18,15-70,9 %, Cu 0,025-2,34 %, Pb <0,001-0,004%, dan Zn 0,033-0,58%.
