Peruvian cement producer Cementos Pacasmayo will use the limestone and diatomite deposits in Bayovar in the northwestern region of Piura to produce Portland-type cement and lime for export to the Pacific countries, Pacasmayo said on August 29, 2007.  
 
Pacasmayo will produce both white and gray Portland cements. Pacasmayo was awarded the project by Peruvian state investment promotion agency ProInversion.  
 
Pacasmayo will carry out some exploration work at the deposits over the next 18 months, Pacasmayo’s CEO, Lino Abram, said. 
 
The company’s cement manufacturing plant in Pacasmayo in the western region of La Libertad is being supplied with limestone from the deposit Tembladera, located in La Libertad. The company owns other limestone deposits in Bayovar, but the deposits awarded now are with higher purity, which allows the production of white Portland cement and lime.
